Speed Post News Network

New Delhi : Upcoming Hot Weather Season (April to June-AMJ) is expected to have the above normal sub-divisional average seasonal temperatures (maximum, minimum and mean) over most of the meteorological sub-divisions of the country except the subdivisions of eastern, east central and southern parts for the country that are likely to experience slightly below normal seasonal temperatures.

The AMJ seasonal average temperatures in most of the subdivisions are likely to be cooler than last year. Normal Heat wave (HW) conditions are likely over core heat wave zone of the country. India Meteorological Department (IMD) issues operational seasonal forecast outlooks for subdivision scale temperatures over the country for both hot and cold weather seasons. These outlooks are generated based on predictions from the Monsoon Mission Coupled Forecasting System (MMCFS) Model and implemented by the office of Climate Research and Services (CRS), IMD, Pune, according to a PIB release.

This year IMD had issued temperature outlook for the pre-monsoon season of March to May (MAM) on  February 28, 2018, in which it was forecasted that warmer than normal temperatures are likely during the MAM season in all meteorological sub-divisions (except Sub Himalayan West Bengal and Sikkim) of the country. Now the seasonal temperature outlook for the 2018 hot weather season of April-June (AMJ) is presented.

The seasonal average maximum temperatures are likely to be warmer than normal by ≥1 °C in Jammu & Kashmir, Punjab, Haryana, Chandigarh & Delhi (HCD) and Himachal Pradesh. They are likely to be between 0.5°C & 1°C in Uttarakhand, West Uttar Pradesh and east and west Rajasthan. Remaining subdivisions are likely to experience near normal (between 0.5°C & -0.5°C) maximum temperature anomalies.

The season averaged minimum temperatures are likely to be warmer than normal by ≥1 °C in Punjab, HCD, west Uttar Pradesh and east and west Rajasthan. They are likely to be between 0.5°C & 1°C in Jammu & Kashmir, Himachal Pradesh, Uttarakhand, east Uttar Pradesh, Bihar, Jharkhand, east and west Madhya Pradesh, Chhattisgarh, Vidarbha, Madhya Maharashtra, Saurashtra and Gujarat. 

The normal heat wave conditions are likely to prevail in the core HW zone during the season. The core HW zone covers states of Punjab, Himachal Pradesh, Uttarakhand, Delhi, Haryana, Rajasthan, Uttar Pradesh, Gujarat, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, West Bengal, Odisha and Telangana and meteorological subdivisions of Marathawada, Vidarbha, Madhya Maharashtra and coastal Andhra Pradesh.
