Contrary to popular belief, global warming does not indicate a decrease in cold waves and an increase in heat waves. We are headed for a world of extremes as a result of climate change brought on by global warming. All types of extreme weather will occur more frequently, including cold waves.
With temperatures in the Indo-Gangetic plain going below average, a cold wave has engulfed North India. However, as the IMD had forecast, there was a small break in the cold for North India on December 29 and 30. Over the Indo-Gangetic plains, temperatures are anticipated to stabilize at 7°C.
North India will welcome 2023 with a biting chill, with only a little respite from the bitter chill of 2022. There will likely be a new cold wave starting on January 1, 2023. Despite the fact that there have been cold waves, this winter will really be reasonably warm with sporadic bursts of icy cold. According to the Indian Meteorological Department (IMD), a region is said to be experiencing cold wave conditions when the temperature remains at or exceeds 4.5°C below average for an extended period of time.
Cold Wave: A Product of Climate Change
The effects of climate change on numerous atmospheric phenomena, including La Nina, Western Disturbances, and the cold wave, have resulted in warmer-than-usual winter conditions as well as continuous severely cold temperatures. Over the Pacific Ocean, there occurs an atmospheric and oceanic phenomenon called La Nina. Surface temperatures in the eastern equatorial and central pacific waters are significantly lower during La Nina. A typical winter with La Nina conditions is colder and wetter than average.
This year, however, that won't be the case due to climate change as the south will see a colder-than-normal winter, and northwest and northeast India will experience a warmer-than-normal summer.
