This set of images helps explain the worrying 2012 monsoon season in South Asia and why drought conditions are emerging in more districts with every passing week.
We are coming up to the eight-week mark of the 2012 monsoon (taking the 04-06 June date as the ‘normal’ for the monsoon to become active over south-west India, after which the climatological system slowly advances over the peninsula and up into northern India).
The Indian Meteorological Department (IMD) has not helped, by maintaining a scientific detachment between forecasting science and the dire situation of farmers and consumers. With emergency drought programmes new being rolled out in many states (more than a month late), the IMD’s refusal to speak plainly to those who need the information the most is unpardonable.
Worse, the Department on its website and its communications walls off its forecasting behind a very unfriendly science interface (see this commentary for a detailed explanation), and appears oblivious about its responsibilities to those for whom it exists – the citizens of India who are waiting for rain.
This set of images (strips below, you can click on the images for the full-size versions) describes what the IMD ought to be disseminating (but stubbornly refuses to). These are 24, 48, 72 and 96 hour regional forecasts for South Asia of accumulated precipitation and temperature extremes.
Day 1 – 02 Aug 2012
Day 2 – 03 Aug 2012
Day 3 – 04 Aug 2012
Day 4 – 05 Aug 2012
The four regions you see in the panels are Peninsular India and Sri Lanka, Western India and Pakistan, Northern & Central India and Nepal, and Eastern India and Bangladesh. These are from the monsoon forecasting sub-site of the Center for Ocean-Land-Atmosphere Studies – of the Institute of Global Environment and Society (IGES) – which processes and synthesises data from the NOAA/NCEP, which is the National Oceanic and Atmospheric Administration (NOAA, the US government agency), National Centers for Environmental Prediction. These regional weather forecasts are presented as a running four-day ensemble of images showing daily forecasts of 2-metre temperature minima and maxima and accumulated precipitation covering the four sub-regions.
