New Delhi: Monsoon is about to bid farewell to the entire country. The Meteorological Department says that the monsoon will completely disappear by October 15. According to IMD, this year the country has received 8% more rainfall than normal. Meanwhile, the Meteorological Department also says that there may be severe cold this year. IMD says that this time there is a possibility of severe cold in North India, especially Delhi-NCR and surrounding areas. This year, such claims are coming out regarding first the scorching heat, then excessive rains and now winter.
Why is it being said that there will be severe cold?
The reason for this is the possibility of La Nina being active during October-November. According to IMD, there is a 71% chance of La Nina conditions occurring in October-November. However, the Meteorological Department also says that the exact forecast of how cold it will be will be available only in November. If La Nina becomes active this month, there may be severe cold in the months of December and January. La Nina usually causes a drop in temperatures. Due to this, there is more rainfall in winter season.What is the effect of La Nina?
During La Niña, easterly winds push ocean water westward. Due to this the surface of the sea becomes cold. According to IMD's estimates, there is a 71 percent chance of La Nina becoming active between October and November. According to IMD Director General Mrityunjay Mohapatra, there is a 71% chance of La Nina conditions occurring in October-November. When La Nina occurs, temperatures in North India, especially North-Western India and the surrounding central region, become below normal.
The World Meteorological Organization has also said this
A report released by the World Meteorological Organization (WMO) last month itself indicates that the current neutral conditions (neither El Nino nor La Nina) will turn into La Nina conditions during October-November. There is a 55 percent possibility of change in this. WMO said that from October 2024 to February 2025, the probability that the strength of La Niña will increase to 60 percent and the probability of El Nino strengthening again during this period are zero.
