IMD hopes to forecast thunderstorms 6-12 hours ahead

Scientists at the India Meteorological Department and other agencies are working to create models to forecast occurrence of thunderstorms six to 12 hours in advance, learning lessons from last year’s deadly storms in pre-monsoon season that killed over 200 people in the North Indian plains, top officials have said.

Mritunjay Mohapatra, IMD Additional Director-General, said a team of scientists from the IMD, the Indian Institute of Tropical Meteorology and the National Centre for Medium Range Weather Forecasting (NCMRWF) are working on models that could forecast the probability of thunderstorms well in advance. The IMD, the IITM and NCMRWF work under the Ministry of Earth Sciences.

M Rajeevan from the Ministry of Earth Sciences said this year, the IMD plans to have Standard Operating Procedures (SOPs) in place for dealing with thunderstorm instances and it will work more closely with the National Diaster Management Authority (NMDA).

Early warnings to States

Sending early warnings to States will give them more time to respond, he said, adding the system should be in place by April. Last year, in May, over 200 people died in thunderstorm incidents. In Rajasthan and Uttar Pradesh alone, violent winds killed nearly 180 people.

The heating of North Indian plains during peak monsoon season, clubbed with winds bringing moisture from the Arabian Sea, the Bay of Bengal or due to a western disturbance, forms conditions that lead to formation of a thunderstorm. “It may form in an hour and dissipate the next hour. But it brings strong winds, rains and lightning ,” Rajeevan said.

The IMD was last year criticised by the two worst-hit States for not forecasting the thunderstorms, a charge it rejected.

Mohapatra said the IMD is also contemplating sending alerts on thunderstorms through Twitter.
