Good news for the people of northern and central India, as there is likely to be a respite soon from the unusually early onslaught of heat that has currently gripped the region. The heat waves reeling around the city is likely to remain no longer than today and after which the temperatures are expected to dip, according to the India Meteorological Department (IMD). A high temperature in central India is a common phenomenon but there was an additional local factor this year which strengthened the heat, reported the Indian Express quoting Mrutyunjay Mohapatra, head of services at IMD.
According to Mohapatra, during this time of the year, the sun is directly above central India, somewhere just south of the 20 degree latitude. The wind direction during this time is southerly, from south to north in the south-west direction. So the heat from central India gets transported upwards to Gujarat, Rajasthan, Delhi, Uttar Pradesh and north-west India. This is common but the but the reason for the unusually high temperature, this year, was the build-up of an anti-cyclonic circulation over Maharashtra, that is a localised and temporary phenomenon. It does not happen every year, he said. Asked about what this circulation is doing? He said it is accentuating the southerly winds. This is amplifying the heat transfer from central India to the northern areas, over states like Rajasthan, Delhi and Uttar Pradesh. This is the reason why these areas are feeling unusually warm at this point of the year, said Mohapatra.

Asked about the days to come, Mohapatra said a western disturbance is developing over the Pakistan-Afghanistan region. This is expected to result in rains in north-west India from today (Saturday), which will help in bringing the temperatures down in most of northern and central India. Once the mercury takes a dip, the relatively colder temperature is likely to persist till April 10, added he.
The highest maximum temperature of the season so far was recorded in Akola in Maharashtra which touched 44 degrees Celsius. Maharashtra has already reported two deaths due to excessive heat.
