Explained: Why winter bid adieu to India early this year too #IndiaNEWS #Education
Temperatures across Northwest and Central India have been settling well above normal, paving way for hot weather, experts warned.
In fact, India faced its hottest February in 2023 since record-keeping began in 1901, with an average maximum temperature of 29. 54-degree Celsius, according to India Meteorological Department (IMD).
Meteorologists are predicting tougher times ahead with increased probability of heatwave during the upcoming summer season. Threat of crop damage has been looming large with the increasing heat stress.
According to scientists, the prevailing weather conditions are a result of increasing global warming, which they have been warning against for quite some time now. Continuous increase in the global mean temperatures has been impacting dynamics of the larger weather phenomena such as western disturbances and ENSO (El Nino Southern Oscillation).
Change in characteristics of these systems has largely affected the precipitation over India during the winter season.
According to meteorologists, the anomaly in the temperatures and rainfall is the result of alterations in the weather patterns. The intensity as well as frequency of western disturbances has been on the lower side this winter season.
The western disturbance is known to drive the weather activities and bring winter to Northwest India and adjoining areas of Central India. Although January saw a good number of active western disturbances, they could not have any impact on the weather across the Indo-Gangetic plains.
By mid-November, both the intensity as well as the frequency of western disturbances started increasing across Western Himalayas. Besides, these bands of clouds also started moving in the lower latitudes, increasing the chances of precipitation.
November is also known as the transition month, allowing winter to seep in. Usually by the end of the month, higher reaches of Himalayan states of Jammu and Kashmir, Himachal Pradesh, and Uttarakhand record one or two spells of moderate to heavy snow and rainfall.
However, this was not the case during November 2022.
Five western disturbances moved across Western Himalayas, out of these, two western disturbance (November 2-5 and 6-9) caused isolated to scattered rain or snowfall over the hilly states and adjoining foothills.
The other three western disturbances were feeble (November 13-15, 18-21 and 22-24) and did not affect the region.
December started on a warmer note. With no rain or snowfall, winter chill kept evading the entire Northwestern plains and the adjoining parts of Central India.
The month saw seven western disturbances, out of these, only one (December 28-30) caused rain or snowfall over Western Himalayas and the adjoining plain areas.
