New Delhi (NVI): The month of October has been recorded as the coldest in 58 years in the national capital, according to India Meteorological Department (IMD).
IMD stated that the mean minimum temperature in October in 2020 was 17.2 degrees Celsius, which is the lowest since 1962, when it was recorded at 16.9 degrees Celsius.
Normally, Delhi records a mean minimum temperature of 19.1 degrees Celsius in October.
Meanwhile on Thursday, Delhi recorded a minimum temperature of 12.5 degrees Celsius – the lowest in the month of October in 26 years. Delhi last recorded such a low temperature in 1994 when it was 12.3 degrees Celsius.
According to IMD data, the normal minimum temperature for this time of the year is 15-16 degrees Celsius.
The absence of cloud cover is a major reason for such low minimum temperatures this time, IMD’s head Kuldeep Srivastava said.
“Clouds trap some of the outgoing infrared radiation and radiate it back downward, warming the ground,” he said, adding, “Another reason is calm winds, which allow formation of mist and fog.”
Winter season mostly depends on western disturbances. When western disturbance approaches northwest India, winter commences.
