The minimum temperature in the national capital dropped to 3.6 degrees Celsius, the lowest this winter on Wednesday, the Met office said. "The minimum temperature was recorded at 3.6 degree Celsius, four notches below the season's average. It is the lowest temperature recorded so far this year," it said. Delhi has been reeling under a cold wave for the past a few days. The fall in temperature is because of cold wave conditions prevailing over northwest India. “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 cool the earth.
