Mercury levels continued to drop in the nation’s capital as Delhi’s minimum temperature dropped to 6.9 degrees Celsius on Sunday, the lowest in November since 2003.
IMD declares a cold snap when the minimum temperature is 10 degrees Celsius or less and 4.5 notches colder than normal for two consecutive days.
“The Safdarjung Observatory, which provides representative data for the city, recorded a low of 6.9 degrees Celsius. This is Delhi’s lowest minimum temperature since November 2003, when the city recorded a low of 6.1 degrees Celsius, “said PTI citing Kuldeep Srivastava, the head of the regional forecasting center of IMD said.
Meanwhile, air quality continues to stay in the “poor” category today with an Air Quality Index (AQI) of 259.
An AQI between 0 and 50 is rated good, 51-100 is good, 101-200 is moderate, 201-300 is poor, 301-400 is very bad, and 401-500 is rated severe.
On Friday, a minimum temperature of 7.5 degrees Celsius was recorded in the nation’s capital, which is its lowest this winter season.
“Delhi recorded a minimum temperature of 7.5 degrees Celsius today, the lowest for this winter season, which starts from October. This is due to snowfall in the lowland and hilly areas. This drop in temperature will continue for the next two days, “Kuldeep Srivastava, an IMD scientist said.
Srivastava said cold, icy winds blowing from the snow-laden western Himalayas caused the mercury to drop.
However, the minimum temperature will increase by two to three degrees Celsius over the next four to five days under the influence of a further western disturbance.
The minimum temperature this month, except Nov. 16, remained 2-3 degrees Celsius below normal in the absence of cloud cover, according to IMD officials.
October was the coldest month for 58 years in the nation’s capital.
