New Delhi: Temperatures in northwest and central India will be more than one degree Celsius above normal for the April-June hot weather season this year, the India Meteorological Department (IMD) said.
According to IMD’s second seasonal outlook for the 2017 summer, normal to above normal temperatures will prevail over the core heat wave zones in the country.
“We are communicating with the states where core heat wave zones are there. We are guiding them how to handle the heat stress if the temperatures rise above 37-40 degee Celsius” said KJ Ramesh,the IMD director general.
Core heat wave zones during the April to June Season cover the states of Punjab, Himachal Pradesh, Uttarakhand,Delhi, Haryana, Rajasthan, Uttar Pradesh, Gujarat, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, West Bengal, Orissa and Telangana and meteorological sub-divisions of Marathwada, Vidharbha, Maharashtra and coastal Andhra Pradesh.
The seasonal average of maximum, minimum and mean temperatures are likely to be higher than normal by 1 degree Celsius in many of the subdivisions of northwest India. Maximum temperatures are likely to be 0.5-1 degree Celsius above normal in many of the subdivisions of central India.
North West India noticed similar scenario in the March to May summer outlook also.
The seasonal average minimum temperatures are likely to be warmer than normal by 1 degree Celsius in most of the subdivisions of the plains of northwest India and by 0.5-1 degree Celsius in the rest of the subdivisions of the country except Konkan and Goa, coastal Karnataka, and sub-Himalayan West Bengal and Sikkim where the minimum temperatures will be warmer than normal by less than 0.5 degree Celsius.
The mean temperatures are likely to be warmer than normal by 0.5-1 degree Celsius in most subdivisions of the country except for Kerala, coastal Karnataka, Tamil Nadu and Puducherry, Saurashtra, Konkan and Goa, Assam and Meghalaya, Nagaland, Manipur, Mizoram and Tripura (NMMT), where the mean temperatures are likely to be warmer than normal by less than 0.5 degree Celsius.
Temperature for some of the southern states are moderated by 0.5 degree Celsius in the second outlook compared to the first one on account of the fact that monsoon arrives in these states in the first week of June.
In its first summer outlook for the months of March to May, IMD indicated that India will experience a hotter-than-normal summer in 2017.
IMD has also started providing extended range forecasts—five-day averaged forecasts for the next 15 days—of heat-wave conditions.
The forecasts are updated after every five days and are made available on IMD’s website.
According to the IMD, neutral ENSO (El Nino Southern Oscillation) conditions are prevailing over the Pacific Ocean. These conditions are unlikely to influence temperatures in India.
The national forecaster has also said that the conditions will have no effect on the June-September south-west monsoon.
