Delhi to witness a mercury level drop up to 4 degree Celsius in the next 3 days

India, in most of its parts, is undergoing winter season and among the most hit states, Delhi is one. As Delhi goes through an extreme chilly winter, there is nothing unusual for the state to experience a drop in the mercury level-up to 5 to 10 degree. But this time, there seems to be an exceptional case as the India Meteorological Department (IMD) forecast says something else only.

As per the IMD forecast, a cold wave is to hit the national capital in the coming 3 days due to which the mercury has a very positive chance of dropping to 4 degree Celsius. If this gets to happen, life is surely going to turn miserable for its residents, especially for the ones who are homeless. Delhi, in fact, in the early hours of Tuesday, the state experienced a temperature of 5.1 degrees Celsius and that makes the day the coldest December day since 2015. But this record seems to be breaking in the next 3 days as the temperature is expected to drop even more.

As forecasted by the experts, the cold wave conditions may be witnessed only at isolated places and the probable dates are December 20, 21 and 22.

The drop in the mercury level to 5.1 degree Celsius on Tuesday marked three notches below the season’s average. On Monday, the city recorded 6.2 degrees Celsius.

The unusual drop in the mercury, according to IMD officials, may be due to clear skies and strong cold winds that are blowing over Delhi due to heavy snowfall in parts of northwest India. Experts have clarified that the night temperature drops due to a clear sky and pushes up the day temperature. Whereas, a cloudy sky does exactly the opposite to this.

Kuldeep Srivastava, head of regional weather forecasting centre (RWFC), IMD, said, “The heavy snowfall — early for this time of the year — in Jammu and Kashmir, parts of Himachal Pradesh and Uttarakhand, has triggered cold winds that are reaching Delhi. The predicted cold wave conditions are mainly because the sky is clear and in the absence of any cloud layer, the cold winds rapidly cools the earth. This phenomenon is called radiation cooling.”
