Following the cold wave, that has gripped several states across North India on Monday, the weather is likely to remain chill with freezing temperatures. According to the Indian Meteorological Department (IMD), severe cold wave conditions will prevail in northwest India till December 21.
On Monday, the temperature in Delhi plummeted to 3.2 degrees Celsius after a bone-chilling "severe" cold was reported in several states including Haryana, Punjab, Rajasthan and Himachal Pradesh. Churu in Rajasthan reported the lowest minimum temperature of minus 2.6 degrees Celsius on Sunday followed by Sikar (minus 2.5 degrees Celsius) and Amritsar (minus 0.5 degrees Celsius).
What is a 'Cold Wave'?The cold wave is a weather phenomenon when the minimum temperature in the plains dips to 4 degrees Celsius. The IMD declares a cold wave when the minimum temperature is 10 degrees Celsius or below and is 4.5 notches less than normal.
A severe cold wave is when the minimum temperature dips to two degrees Celsius or the departure from normal is more than 6.4 degrees Celsius.
In other words, when the minimum temperature is less than or equal to 10 degrees Celsius and the maximum temperature is at least 4.5 degrees Celsius below normal, it is said to be a cold day.
Cold wave to continueThe IMD has predicted that the cold wave conditions, currently gripping northern India, will continue in northwest India for the next two days, and over central and East India for the next three days.
Cold wave conditions are very likely to prevail over parts of Uttarakhand, Uttar Pradesh, Maharashtra, Bihar and Jharkhand till Wednesday afternoon and over Jammu, Kashmir-Ladakh-Gilgit-Baltistan-Muzaffarabad, Himachal Pradesh, Gangetic West Bengal till Tuesday afternoon and are very likely to abate thereafter.
A cold wave is also predicted in parts of Chhattisgarh and Odisha till Thursday afternoon.
Dense fog is predicted in the morning hours in parts of Punjab and Haryana from December 23 to December 25 and over western Rajasthan on December 24 and 25.
