The India Meteorological Department( IMD) has advised of an approaching cold surge in certain countries of North India, with night and day temperatures anticipated to drop between January 5 and 11. According to IMD Director General Dr. Mrutynjay Mohapatra, this could lead to cold surge conditions in central India, particularly in Madhya Pradesh, Northern corridor of Maharashtra, Southern corridor of Uttar Pradesh, and areas of Haryana and Rajasthan. The IMD predicts below-normal day temperatures and cold day conditions during this period.
Mohapatra also mentioned the conformation of a low-pressure area in the southeast Arabian Sea, performing in pall cover over Lakshadweep and the Maldives islets. Heavy downfall is anticipated in Lakshadweep over the coming three days, accompanied by strong winds of 40–50 kmph. Fishers have been advised to avoid venturing into the ocean.
IMD predicts a downfall in January
In a yearly cast for January, the IMD anticipates a normal downfall throughout the January-February-March period. Dr. Mohapatra stressed that 2023 was the alternate warmest time since 1901, with over-normal periodic mean air temperatures. He explained that while the utmost corridor of the country will witness fairly warmer mornings, the central and northwestern regions can anticipate cooler days with below-normal yearly maximum temperatures.
The IMD also prognosticated thick to veritably thick fog in the corridor of northwest India and East India, extending into portions of Bangladesh. Also, cold-day to severe cold-day conditions are anticipated to persist in certain areas of Punjab, Haryana, Uttar Pradesh, and northern Rajasthan for the coming two days.
What’s the meaning of a cold surge?
In the environment of the Indian Meteorological Department, a cold surge is characterised qualitatively as a condition where air temperatures become dangerous to mortal health upon exposure. Quantitatively, it’s defined as grounded on temperature thresholds over a region in terms of factual temperature or its departure from becoming normal.
The meteorological claim is that the inflexibility of a cold surge is determined by factors similar as the cold indicator, which combines air temperature and wind speed, as well as cold discomfort, social/ artistic, and physiological factors.
The major factors contributing to a cold surge in India include the buildup of a crest in the spurt sluice over northwest Asia, the conformation of face high pressure over north and central India, the movement of cold air millions steered by upper-position winds, driving mechanisms like strong westerly swells, and expansive snow cover over the Northwest Himalayas.
