Guwahati News Desk: According to the India Meteorological Department (IMD) data, the national capital witnessed the coldest October in 58 years.
The minimum temperature in October this year was 17.2 degrees Celsius, the lowest since 1962, when it was 16.9 degrees Celsius, the IMD said.
Delhi normally records a mean minimum temperature of 19.1 degrees Celsius in October.
“The absence of cloud cover is a major reason for such low minimum temperatures this time. Clouds trap some of the outgoing infrared radiation and radiate it back downward, warming the ground. Another reason is calm winds, which allow formation of mist and fog,” said Kuldeep Srivastava, the head of the IMD’s regional forecasting center.
