New Delhi, November 2
With temperatures dropping below normal over many parts of Northwest, bringing a sudden nip in the air, meteorologists are suspecting a “harsher/colder and an extended winter” this season due to various reasons-local/regional apart from prevailing La Nina conditions.
The national capital today recorded a minimum temperature of 10.8 degrees Celsius, the lowest this season so far. Normally in the first week of November the Safdarjung Observatory records a minimum of 14 to 16 degrees Celsius. The mercury dips to 11-12 degrees Celsius by the last week of November, according to IMD officials.
The IMD says temperatures remained “appreciably below normal (-3.1°C to – 5.0°C) at places over Jammu & Kashmir, Ladakh, Gilgit-Baltistan and Muzaffarabad and below normal (-1.6°C to -3.0°C) over West Uttar Pradesh, East Rajasthan, Haryana, Chandigarh and Delhi in the past 24 hours with Hissar recording the minimum temperature of 8.9 degrees Celsius.
As per Mahesh Palawat of Skymet Weather, November 1 was the coldest in the past 10 years in the capital and that similar conditions are also prevailing in adjoining regions. Predicting a “harsher and extended winter this season”, he says there are three main reasons for early drop in temperatures this year — dry weather, lesser/weaker Western Disturbances and clear skies. “There has not been much snowfall in the hills as most of the WDs have been feeble. Around Diwali, a strong WD is expected to bring snow to hills, which will result in a drop in temperatures. Also, this is a La Nina year and La Nina conditions coincide with extended winter,” Palawat said.
IMD Director-General Mrityunjaya Mohapatra said: “Generally, during a La Nina year temperatures remain low but a lot depends upon regional factors, winds, etc. The IMD will be issuing a detailed weather forecast for the season later this month.”
