Why spring gave north India a miss this year? IMD explains

The residents of Delhi and North India are witnessing an increase in temperatures which is quite unusual for this time of the year. This weather phenomenon can be blamed on the absence of Northwesterly Winds. 

"Normally, six western disturbances impact the northern plains in January and February and about four to five in March. The northwesterly winds bring pleasant springtime weather as we head to summer. That hasn’t happened this year," said Kuldeep Srivastava, head of regional weather forecasting centre, IMD.

“Only one WD each impacted the NW plains in January and February each. The rest of the WDs impacted only the upper reaches of the Western Himalayas. Warm south-westerly winds have been blowing,” he further stated.

Srivastava added that there might be a slight relief in maximum temperatures starting from Sunday (February 28) to the middle of this week but then it will heat up even more. 

“It may result in a 2-3 degree Celcius drop in maximum temperatures over the plains till March 3. But maximum temperatures are already 5 to 6 degrees Celcius above normal, so a 2-3 degree Celcius drop won’t bring back spring. From March 3, maximums will rise again to 34 to 35 degree C,” Srivastava said.

In its summer forecast for March to May, the IMD predicted that day temperatures are likely to be above normal in north, northeast, parts of east and west India. However, it has forecast a likelihood of below-normal temperatures in the south and adjoining central India.

The Indian Meteorological Department has predicted high maximum temperatures in Chhattisgarh, Odisha, Gujarat, coastal Maharashtra, Goa and coastal Andhra Pradesh. 

"However, below normal seasonal maximum temperatures are likely over most of the subdivisions of the south peninsula and adjoining central India," IMD forecast said. 

The entire Indo-Gangetic Plains (IGP) region, including Haryana, Chandigarh, Delhi and Uttar Pradesh, is likely to experience both hot days and warm nights during the March to May season, the IMD said on March 1. 

IMD is working on  new policies for better preparedness during summer. It will issue heatwave warnings valid up to five days daily which will be updated by the national weather forecasting centre. Impact-based heatwave warning will also be issued wherein the general public will be advised how to protect themselves.
