Between contemplation and climate

June 8, 2017 by Climate portal editor Leave a Comment

Whether or not the USA, Europe, the Western world, the industrialised Eastern world (China, Japan, South Korea, Taiwan), adhere to or not their paltry promises about being more responsible concerning the factors that lead to climate change, is of very little concern to us. We have never set any store by international agreements on climate change.

This year will see the twenty-third conference of parties of the UN Framework Convention on Climate Change and for 23 years the world and India have listened to lofty tales about simple science. In these 23 years, neither has reckless consumption been halted nor has the economic model that encourages such reckless consumption been questioned by the conference of parties. As long as they do not, inter-governmental agreements are useless.

That is why we find unnecessary and pointless the hand-wringing that has taken place about the decision of the government of the USA to exit what is called the ‘Paris Agreement’, the December 2015 document agreed to and signed by practically every country which has some fuzzy paragraphs about low-carbon economy, innovation, technology, energy and finance – all of which have very much to do with the hold of the finance capitalists and the global technocrats over the international systems of our time.

President number 45 of the USA is neither wiser than nor baser than the wisest of basest of any of his predecessors: the American political system has to do entirely with the desire to dominate other countries. Number 45’s manner may be irksome, but through him speaks the American finance capital, its bloatsome defence industry and its insensate technology industry.

We do not expect the chiefs of the Western countries, the so-called major powers of the European Union, and their allies such as Japan and Australia to do any less. They are no different. We do not think any of them, their armies of bland advisers, their bankers and the brigades of industrialists great and petty who crowd their corridors of governance have read, much less reflected, on the lambent wisdom of our civilisation.

Many centuries ago, in the section of the Digha Nikaya, or Collection of Long Discourses, called Samannaphala Sutta, or the Fruits of the Contemplative Life, it was written that there are those who are addicted to debates and shout: “You understand this doctrine and discipline? I’m the one who understands this doctrine and discipline. How could you understand this doctrine and discipline? You’re practicing wrongly. I’m practicing rightly. I’m being consistent. You’re not. What should be said first you said last. What should be said last you said first. What you took so long to think out has been refuted. Your doctrine has been overthrown. You’re defeated. Go and try to salvage your doctrine; extricate yourself if you can!”

And this is how we view what are called climate negotiations, between the experts of countries. We care not for the arguments of number 45 of the USA, for what many in the world in the last week have protested as being absurd – it undermines economy, it takes away jobs, it is unfair, it is disadvantageous to us, and so on – is what they cheer and support their own countries for in areas where they stand to gain, such as trade (to sell cheap and useless goods), technology (to enslave and control), finance (to spin webs of debt), processes of modernisation (to homogenise cultures so that ever more ‘markets’ come into being).

We in India need no such instruction. But we must guard against our philosophies being swept away by these agreements, these grand comities of nations, the barrage of numerics and scientifics that are invented to display to us what a threat we are should we not emulate the West and its ways. We must guard against our own who prefer the baubles of post-industrial society to the intellectual and spiritual riches of our civilisation, and who seek to infest India with the same technological and ‘modern’ wares that so entranced the West and doomed its folk. This has very little to do with climate and its change and very much more to do with our Indic sciences and their worth, our conduct and our duty to Punyabhoomi Bharat.

Dry districts alert, May 2017

May 1, 2017 by Climate portal editor Leave a Comment

A large number of districts in south, peninsular, central and eastern India are experiencing dry and semi-arid conditions which will continue, and likely become worse, until the 2017 monsoon becomes active.

This list of districts is based on our re-working of the maps released weekly by the India Meteorological Department (Hydromet section in Pune), which show the district-level standardised precipitation index (or SPI). While this is not a drought or dryness index, the weekly SPI serves as a very reliable indicator of where water stress is occurring, and is therefore an invaluable aid for relief planning.

In this series of four maps, re-coloured by us to better display differences in SPI between regions and over time, the change in south India stands out.

Each map displays the SPI as a cumulative reading of the four weeks until the date given. That is why the change for any district – from ‘moderately dry’ to ‘severely dry’ for example – needs to be seen as having an immediate bearing on the available water, crop health and condition of forest and pasture for that district.

Based on the readings for 26 April 2017 this is the list of districts that need urgent attention.

Maharashtra: Gadchiroli, Chandrapur, Yavatmal, Kolhapur
Chhattisgarh (Raipur division): Gariaband, Raipur, Baloda Bazar
Odisha: Rayagada, Kandhamal, Angul, Cuttack
West Bengal: 24 Parganas North
Manipur: Chandel
Andhra Pradesh: Vizianagaram, Kurnool
Telengana (old district boundaries): Nizamabad, Karimnagar, Medak, Warangal, Khammam, Mahbubnagar
Karnataka: Bidar, Raichur, Bijapur, Bagalkot, Koppal, Gadag, Dharwad, Bellary, Shimoga
Tamil Nadu: Cuddalore, Nagapattinam, Tiruvarur, Thanjavur, Pudukkottai, Ramanathapuram, Toothukudi, Kaniyakumari, Theni, Coimbatore
Kerala: Malappuram, Thrissur, Ernakulam, Kottayam, Alapuzha

Big water storage wheel

April 29, 2017 by Climate portal editor Leave a Comment

The Central Water Commission, Ministry of Water Resources, Government of India, monitors every day the quantity of water stored (and used from) each of the 91 major reservoirs of the country. It issues a bulletin every week that gives the weekly storage position of these reservoirs – the volume of water, the level of water in the reservoir and the change from the last week, the change from the same date last year and from the average on this date of the last ten years.

The water storage capacity of these 91 reservoirs taken together is 157.799 billion cubic metres (bcm) which is estimated to be about 62% of the total water storage capacity (in other smaller dams and storage structures all over the country) that has been built and is being used, and which is approximately 253.38 bcm. Out of these 91 reservoirs, hydro-electric power stations (with a capacity of 60 megawatts and more) are attached to 37 reservoirs.

In this illustration by Indiaclimate, for the first time the total storage capacity of the 91 major reservoirs has been visually mapped to show reservoir, state and zone capacities relative to each other and the total.

South India’s water emergency

April 11, 2017 by Climate portal editor Leave a Comment

ICP_res_20170410_topBy the end of the first week of April 2017, the most current and reliable indicator for stored water in south India showed how dire the situation has become. And the South-West monsoon is still about eight weeks away. The weekly data sheet on the stored water quantities in the 91 major reservoirs of India, which is maintained and released by the Central Water Commission, has in the 6 April 2017 release shown the scale of the water emergency.

Of the 31 reservoirs in the southern region (Kerala, Tamil Nadu, Karnataka, Telengana and Andhra Pradesh) that are among the major reservoirs of India, 18 have stored water that is less than 15% of their full capacities.

These 18 are (ranked by least water stored):
Nagarjuna Sagar, APTG, 0.00%
Sholayar, TN, 0.00%
Almatti, KAR, 0.03%
Kabini, KAR, 2.25%
Vanivilas Sagar, KAR, 2.74%
Tungabhadra, KAR, 3.21%
Vaigai, TN, 4.07%
Parambikulam, TN, 5.00%
Malaprabha (Renuka), KAR, 5.56%
Hemavathy, KAR, 5.72%
Mettur (Stanley), TN, 6.72%
Periyar, KER, 6.94%
Bhadra, KAR, 9.02%
Lower Bhawani, TN, 9.09%
Srisailam, APTG, 9.44%
Krishnaraja Sagar, KAR, 11.44%
Malapmuzha, KER, 11.61%
Aliyar, TN, 14.74%
(TN is Tamil Nadu, KER is Kerala, KAR is Karnataka, APTG is Andhra Pradesh and Telengana)

ICP_south_water_20170411

Using a municipal average of about 400 litres per day per household that is a typical designed supply (not delivered, for that’s another tale), how much water does this allow for the 60.51 million households of the southern region until the monsoon begins?

Tamil Nadu has 18.46 million households, Kerala has 7.83 million, Karnataka has 13.3 million, Andhra Pradesh and Telengana have 20.92 million. These together need 24.2 billion litres a day or, in reservoir storage terms, 0.024 billion cubic metres (bcm) a day. The 31 major reservoirs of southern India together have, as of 6 April 2017, 6.583 bcm. From this quantity is taken water for industrial, agricultural and commercial use.

These uses are given priority or water stocks are secured (never mind allocation and metering) especially by industry. Normally, what remains for household use is about a third of the available stock. This leaves, as on 6 April, about 2.19 bcm for household use, which will suffice the 60.51 million households of south India for about 90 days – but only provided, and this is the stringent, non-negotiable condition that must be enforced, all households especially urban keep within the 400 litres per household per day limit.

The situation does not improve even if the monsoon arrives on time and the first weeks deliver normal rainfall. It is only by July 5-15 that reservoir water stocks begin trending upwards. This is where the 90-day restricted supply can take south India to. But only if immediate and strict rationing is imposed, as it should have been, to allow for climatological variance, by 1 March 2017.

The ‘Hindu’, ignorant about weather and climate, but runs down IMD

September 2, 2016 by Climate portal editor Leave a Comment

ICP_IMD_Hindu_comment_20160901

We find objectionable the report by ‘The Hindu’ daily newspaper accusing the India Meteorological Department of scientific shortcoming (‘IMD gets its August forecast wrong’, 1 September 2016). The report claims that the IMD in June 2016 had forecast that rains for August would be more than usual but that the recorded rain was less than usual.

This is nothing but cheap sensationalising by the newspaper of a non-issue. In so doing the ‘Hindu’, which is considered one of Bharat’s national newspapers, has attempted to tarnish the work of not only the India Meteorological Department, but also the work of the earth observation technical community which serve us in the several institutions and agencies of the Ministry of Earth Sciences.

There is no mainstream news media in the country – no daily newspapers, no magazine or periodical, no television channel, no internet website – which possesses the competence to assess the scientific quality and correctness of output of the government earth science agencies, and whose output is delivered to the public every day, several times a day. ‘The Hindu’ certainly does not and with this report exposes its ignorance about meteorology and climate science and observation.

Concerning the newspaper’s claim, rainfall for the period 1 June to 31 August in the 36 meteorological sub-divisions of Bharat, as an area-weighted average, is -3% of the long period average and is therefore well within the boundaries set by both the first stage and second stage forecasts provided by the IMD. Of the 36 sub-divisions, for this period 24 sub-divisions have recorded normal rainfall, four have excess and eight (including the two island sub-divisions) have deficient rainfall. In what way is this an erring forecast?

The news report in the ‘Hindu’ states that the forecasting error it has found “suggests that the agency’s weather models are still not robust enough to capture changes in global climate that could affect” our monsoon. This is nonsense.

The earth observation agencies of the MoES – of which the IMD is a part – for the June to September monsoon forecast employs a group of six parameters that inform the forecast (together called an ensemble forecasting system). These are: north-east Pacific to north-west Atlantic sea surface temperature anomaly gradient, south-east equatorial Indian Ocean sea surface temperature, East Asia mean sea level pressure, central Pacific (El Nino region 3.4), sea surface temperature and tendency, north Atlantic mean sea level pressure and north-central Pacific 850mb wind gradient. In what way does this not look at global climate?

Moreover, the IMD and the agencies of the MoES (notably the Indian Institute of Tropical Meteorology) work closely regionally and internationally on climate science, weather prediction and monitoring. Not only is the IMD implementing for the World Meteorological Organisation (WMO) a Regional Climate Centre for South Asia, the monsoon prediction and monitoring system relies on collaboration with: the National Centers for Environmental Prediction (NCEP) of USA, the European Centre for Medium-Range Weather Forecasts (ECMWF), the Japan Meteorological Agency (JMA), the Met Office Hadley Centre for Climate Science and Services of UK, and with the national meteorological agencies of Bangladesh, Bhutan, the Maldives, Myanmar, Nepal, Pakistan, and Sri Lanka.

And furthermore, it is because the Earth System Science Organisation agencies and institutes revise, review and upgrade forecasting models, computing wherewithal and methods continuously that we have in 2016 an experimental forecast (based on the Monsoon Mission coupled dynamical model).

‘The Hindu’ newspaper has presented its own uninformed reading of differences in forecast averages to make an absurd claim against the IMD, neglecting entirely to mention the extremely valuable service provided, at the district and even at the block level, to Bharat’s kisans via daily sms on weather which will affect crops; neglecting the several excellent initiatives launched by the Department since 2015 on localising forecasts for towns and cities (in close coordination with the National Remote Sensing Centre of the Indian Space Research organisation, the Meteorological and Oceanographic Satellite Data Archival Centre of ISRO’s Space Applications Centre, and the Indian National Centre for Ocean Information Services.

A race between monsoon and water

June 1, 2016 by Climate portal editor Leave a Comment

ICP_reservoirs_20160601

The southern states of Tamil Nadu, Karnataka, Andhra Pradesh and Telengana are in dire need of rainwater to replenish exceedingly low levels in reservoirs and all surface water structures. This water has come in the form of showers over the past five or six days, although the spread of the rainfall has been patchy, and whether rainwater has collected in significant quantities and percolated into sub-soil aquifers will not be known for at least another week.

Until 31 May 2016 the stored water situation as measured by the quantities recorded in the 91 major reservoirs of India was very grave indeed. The most recent weekly bulletin of the Central Water Commission, which monitors what is called the ‘live storage status’ of the 91 major reservoirs, was issued on 26 May. Out of the 91 reservoirs, 37 have hydro-electric power plants which deliver electricity to the states in which these reservoirs are and to the national grid.

The total ‘live storage’ capacity of these 91 reservoirs is 157.799 billion cubic metres (BCM) which is estimated as being about 62% of the total storage capacity of 253.388 BCM that is estimated to have been built or created. But the 26 May bulletin placed the total storage available in these reservoirs at 26.816 BCM, which is 17% of the total of 91 reservoirs. At this time in 2015, the total stored water was 49.119 BCM and the average of the last 10 years of storage at this time was 33.764 BCM. Thus, the stored water for the week ended 26 May is 55% of the quantity stored in 2015 and 79% of the quantity stored at this time averaged for the last ten years.

ICP_reservoir_trends_20160601

The Northern region is Himachal Pradesh, Punjab and Rajasthan. There are six reservoirs with total live storage capacity of 18.01 BCM. By 26 May the total storage in these reservoirs was 3.91 BCM which is 22% of the total live storage capacity. The stored volume at the corresponding period in 2015 was 43% and the stored volume of the average corresponding period of the last ten years was 29%.

The Eastern region is Jharkhand, Odisha, West Bengal and Tripura. There are 15 reservoirs with total live storage capacity of 18.83 BCM. By 26 May the total live storage in these reservoirs was 4.22 BCM which is 22% of total live storage capacity. The stored volume at the corresponding period in 2015 was 34% and the stored volume of the average corresponding period of the last ten years was 20%.

The Western region is Gujarat and Maharashtra. There are 27 reservoirs with total live storage capacity of 27.07 BCM. By 26 May the total live storage in these reservoirs was 3.90 BCM which is 14% of total live storage capacity. The stored volume at the corresponding period in 2015 was 26% and the stored volume of the average corresponding period of the last ten years was also 26%.

The Central region is Uttar Pradesh, Uttarakhand, Madhya Pradesh and Chhattisgarh. There are 12 reservoirs with total live storage capacity of 42.30 BCM. By 26 May the total live storage available in these reservoirs is 9.59 BCM which is 23% of total live storage capacity. The stored volume at the corresponding period in 2015 was 33% and the stored volume of the average corresponding period of the last ten years was 18%.

The Southern region is Andhra Pradesh, Telengana, combined projects in both states, Karnataka, Kerala and Tamil Nadu. There are 31 reservoirs with total live storage capacity of 51.59 BCM. By 26 May the total live storage available in these reservoirs was 5.21 BCM which is 10% of total live storage capacity. The stored volume at the corresponding period in 2015 was 27% and the stored volume of the average corresponding period of the last ten years was 20%.

Prepare for May heat

May 4, 2016 by Climate portal editor Leave a Comment

ICP_May_heat_20160504The heat outlook for the first half of May, which was released by the India Meteorological Department (IMD) on 02 May, calls for immediate attention and preparation on all fronts.

The forecast is for three periods of five days each (called pentads) with expected temperature anomalies given for maximum and minimum temperatures. The big picture is that over some parts of the country maximum temperatures will remain 3-4 C above normal for all the three pentads.

Minimum temperatures that are 1-5 degrees higher than normal will increase in terms of the geographical range as the days progress through the first, second and third pentad: 02 to 06 May, 07 to 11 May and 12 to 16 May.

There are several particular alerts arising from the IMD heat wave outlook:

The heat outlook for the first half of May, released by the India Meteorological Department (IMD), for the three five-day periods of 02 to 06 May, 07 to 11 May and 12 to 16 May.

The heat outlook for the first half of May, released by the India Meteorological Department (IMD), for the three five-day periods of 02 to 06 May, 07 to 11 May and 12 to 16 May.

1. Odisha, Gangetic West Bengal and south Chhattisgarh, which have seen some record-breaking high temperatures in April, will continue to see above normal maximum temperatures.

2. South Interior Karnataka, coastal Maharashtra and Goa (the Konkan), and Saurashtra will experience a gradual rise in maximum temperatures from the first to third pentad.

3. Maximum and minimum temperatures both, in Jammu and Kashmir, Himachal Pradesh and Uttarakhand will remain around 5 C above normal for the duration of the forecast.

4. The 12 to 16 May period (third pentad) will see higher than normal maximum temperatures (2 to 5 C) over almost the entire country, and higher than normal minimum temperatures over most of the country.

Other observations are:

5. The North-East will experience minimum temperatures about a degree higher than normal during 07 to 16 May.

6. For the second pentad, that is 07 to 11 May, maximum temperatures in north-west India (Punjab, Haryana, western Uttar Pradesh, Rajasthan, western Madhya Pradesh, Delhi) will drop by 2 to 3 C.

7. Coastal Andhra Pradesh, Rayalaseem and Tamil Nadu will experience lower minimum temperatures by 1 to 2 C during 07 to 16 May.

Please observe basic precautions during this period in particular: eat smaller meals more often; drink water even when not thirsty; avoid tea, coffee and alcohol; plan your activities to avoid being outdoors during 11am to 4pm; do not leave children in cars by themselves; keep a watch on the elderly especially those who are infirm or invalid; wear non-synthetic non-polyester light-coloured and loose fitting clothes; if working outdoors rest frequently; provide drinking water and shade to animals and pets.

Why we need to save water right now

April 16, 2016 by Climate portal editor Leave a Comment

ICP_reservoirs_20160417

Every week, the Central Water Commission release the “live storage” data. By this the Commission means the quantity of water stored in what are called the 91 major reservoirs of India. From this group of what are also called the big dams – they are the biggest in the country – 37 have hydro-electric power plants attached that use the flow of water to generate electricity.

Together the 91 reservoirs can store, if they were full, 157.799 billion cubic metres (BCM). This amount is calculated as being about  62% of the entire “live storage” capacity of 253 BCM which is estimated to have been built as dams in India.

The CWC’s latest bulletin of 13 April 2016 delivers to us an immediate warning: the water stored in these major reservoirs together is under a quarter of their full storage level. The combined quantity stands at 35.839 BCM, which is 23% of the total live storage capacity of these reservoirs. This quantity is 67% of what was stored at this time last year, and is 77% of the average for ten years that is stored at this time of the year. This means we have less stored water compared with last year and compared with the ten year average for this time of year.

Here follows our sequence of alerts put out over the @indiaclimate Twitter feed:

Today, the 91 major reservoirs together hold 35.83 billion cubic metres (bcm) of #water. When all full they can hold 157.79 bcm

Water saving measures must immediately be followed by all households. Town and city municipal corporations and councils must immediately ask residents to reduce their use of water especially on activities like washing cars, watering lawns and swimming pools. District administrations need to immediately implement contingency plans for conserving water.

A tribute to the weathermen of Bharat

April 12, 2016 by Climate portal editor 9 Comments

ICP_IMD_tribute_pic_20160412

When the weather causes anxiety, in the districts and towns, harassed administrators and the impatient public turn quickly to the weatherman. Whether for advice about a possible heat wave, about thunderstorms or hail storms, about extended dry spells, about the possibility of rainfall during a crop sowing period one week distant, it is the local weatherman who has the knowledge and provides the answers.

That weatherman – and weatherwoman, for the service has a number of women scientists – is from the India Meteorological Department, the weather watchers for Bharat.

Theirs is often a thankless task, of poring over the output from instruments and computations, ensuring that the essential information about weather conditions six, 12 or 24 hours hence is transmitted to all those to whom it matters.

Our weathermen scan the skies with their instruments so that they can issue, to airports and airfields all over Bharat, the ‘meteorological aerodrome report’ (or METARs) on which all our commercial flights depend. Our weathermen scan the seas with their instruments to issue the sea weather reports and fleet forecasts for marine traffic in the Arabian Sea, the Bay of Bengal, the Andaman Sea and the nearer Indian Ocean.

India Climate portal thanks readers for the appreciative responses to this tribute, and for the comments (below) which we urge the Ministry of Earth Sciences to consider.

Our weathermen scan the atmosphere with the aid of the orbital eyes of our satellites so that, for every single district, an agricultural meteorology forecast is issued every day and for every crop season. Our weathermen scan the routes of the Indian Railway system, the largest and most heavily utilised in the world, for threatening weather conditions that would affect the running of trains. They do this every single day, round the clock.

Today the India Meteorological Department has issued its first forecast for the 2016 monsoon, the Indian summer monsoon, whose patterns have been so well known for all our recorded history. It is a forecast that has been impatiently awaited this year, because of the shortages of water in our river basins, because of the likelihood – as ever – of heat waves, and because we have been so very worried about whether we will get the rains that eluded Bharat in 2015 and 2014.

The short answer is: yes we will. The details of the percentages, the probabilities, the averages, the likely ranges and other ponderables are all over the news. We’d like to compliment the people behind the forecast.

We sincerely thank the women and men of the India Meteorological Department for their extraordinary efforts – every day, week, season and year – to serve us. The IMD today provides us, in the public domain, through the internet, via television, with the help of mobile phone messages, and through smartphone apps, an array of weather services. These scientists, administrators, technicians and field staff have worked as hard to make this range of services available to us as they have worked to understand our ‘mausam’ better. Theirs is a science whose complexity defies the most powerful computing systems available, and they translate what they see into language that guides us as we go about our daily routines. It calls for a breadth of skills that must be applauded.

A sense of history and philosophy guides their work. The scientists and technicians of the Department take as much inspiration from the Upanishads (which contain serious discussion about the processes of cloud formation, rain, and the seasonal cycles) and from Varahamihira’s classical work, the Brihatsamhita, as they do from the insights that they collaborate on today in what is known as earth systems science. It is a remarkable legacy that is very much alive in the offices and field stations of the IMD.

For their work, and as representatives of the widely distributed IMD network of staff, we thank:
Director General of Meteorology, Laxman Singh Rathore; Additional Director General of Meteorology (Research), Bishwajit Mukhopadhyay; Deputy Director General of Meteorology (Upper Air Instruments), Devendra Pradhan; Deputy Director General of Meteorology (Surface Instruments), Rajesh Ramdas Mali; Deputy Director General of Meteorology, Regional Meteorological Centre New Delhi, Anand Kumar Sharma; Deputy Director General of Meteorology, Regional Meteorological Centre Mumbai, K S Hosalikar; Deputy Director General of Meteorology, Regional Meteorological Centre Kolkata, Gakul Chandra Debnath; Deputy Director General of Meteorology, Regional Meteorological Centre Chennai, S Bagulayan Thampi; Deputy Director General of Meteorology, Regional Meteorological Centre Guwahati, Sanjay Oneill Shaw; Deputy Director General of Meteorology, Regional Meteorological Centre Nagpur, P K Nandankar; Head, Agromet Services K K Singh; Deputy Director General of Meteorology, Satmet, New Delhi, Ashok Kumar Sharma; Deputy Director General of Meteorology, Hydromet, New Delhi, Surinder Kaur; Deputy Director General of Meteorology, Services, New Delhi, Brahma Prakash Yadav; Deputy Director General of Meteorology, Organisation, New Delhi, S D Attri; Deputy Director General of Meteorology, EMRC, New Delhi, Sunil Kumar Peshin; and Deputy Director General of Meteorology, Numerical Weather Prediction, New Delhi, Swapan Kumar Roy Bhowmik. Thank you all for a job very well done indeed.

Preparing for the Indian summer

The India Meteorological Department (IMD) has issued its forecast for the 2016 hot weather season (April to June). The forecast shows that during the 2016 hot weather season, temperatures (mean, maximum and minimum) in all the sub-divisions are likely to be above normal. All the temperatures (maximum, minimum and mean) of most of the subdivisions from northwest India, Kerala from south India and Vidharbha from Central India are likely to be above normal by 1.0° C or more. Read the full forecast document here (pdf).

The season averaged maximum temperatures of coastal Andhra Pradesh, Odisha, Assam and Meghalaya, sub-Himalayan west Bengal and Sikkim, and NMMT – Nagaland, Manipur, Mizoram and Tripura – are likely to be warmer by 0.5° C and that of the remaining subdivisions are likely to warmer than normal by 0.5° to 1° C. The season averaged minimum temperatures of sub-Himalayan west Bengal and Sikkim, and NMMT are likely to be warmer than normal by <0.5° C and that of the remaining subdivisions are likely to warmer than normal by 0.5° to 1° C.

There is also a high probability (76%) of maximum temperatures in the core heat wave zone during the 2016 hot weather season to be above normal. The core heat wave zone covers the states of Punjab, Himachal Pradesh, Uttarakhand, the National Capital Territory and Delhi, Haryana, Rajasthan, Uttar Pradesh, Gujarat, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, West Bengal, Odisha and Telengana and the meteorological sub-divisions of Marathwada, Vidharbha, Madhya Maharashtra and coastal Andhra Pradesh. This in turn suggests high probability of moderate and severe heat wave conditions in the core heat wave zone during the hot weather season.

From this season, the IMD will also provide extended range forecasts (five–day averaged forecasts for the next 15 days) of heat wave conditions over the country. This will be based on the Dynamical Extended Range Forecasting System developed by the Indian Institute of Tropical Meteorology (IITM) in Pune. The forecast will consist of the probability of occurrence of hot days, heat waves and severe heat waves for the next 15 days updated every fifth day from 1 April, 2016. The forecasts will be available on the IMD website.

Between contemplation and climate

Whether or not the USA, Europe, the Western world, the industrialised Eastern world (China, Japan, South Korea, Taiwan), adhere to or not their paltry promises about being more responsible concerning the factors that lead to climate change, is of very little concern to us. We have never set any store by international agreements on climate […]

The ‘Hindu’, ignorant about weather and climate, but runs down IMD

We find objectionable the report by ‘The Hindu’ daily newspaper accusing the India Meteorological Department of scientific shortcoming (‘IMD gets its August forecast wrong’, 1 September 2016). The report claims that the IMD in June 2016 had forecast that rains for August would be more than usual but that the recorded rain was less than […]
