According to Bloomberg‘s report, South Asia is set to witness extreme cold winter due to the La Nina that has been emerging in the Pacific Ocean. Temperatures are set to fall as low as 0-3 degrees Celsius.
Change in pressure of tides in the Pacific Ocean region
La Nina, a Latin term for “little Child”, is an outcome of the change in pressure of the tides in the Pacific Ocean region due to the change in temperature as a result of environmental conditions between the Equatorial and Southern Pacific Ocean.
The impact is said to be concentrated in the equatorial region resulting in severe cold weather in the Northern Half of the Equator. During the months of ‘December-January-February’, the temperature in the South Asian region is expected to go down to about 3 degrees Celsius and cause an energy crisis in India.
China and other Asian countries may face more adverse effects during this period.
Lack of sea ice in the Arctic’s Kara Sea
Besides La Nina, other factors can impact the region’s winter weather, according to Todd Crawford, Director of Meteorology at Atmospheric G2, who mentioned that “Climate change has led to a lack of sea ice in the Arctic’s Kara Sea, which may be contributing to high-pressure ridging in that area. This leads to downstream colder conditions across northeast Asia”.
India has already witnessed unusually heavy rains in several parts of the country.
