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 there is a possibility of severe cold this time in North India, especially Delhi-NCR and surrounding areas. This year, such claims are coming out regarding first scorching heat, then excessive rain 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 forming 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 is 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 rain in winter also.What is the impact of La Nina?
During La Niña, easterly winds push ocean water westward. Because of this the surface of the sea becomes cold. According to IMD estimates, there is a 71 percent chance of La Nina being 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, the temperature in North India, especially North-Western India and the surrounding central region, becomes below normal.
World Meteorological Organization also said this
The 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 chance of it changing. WMO said that from October 2024 to February 2025, it is likely that the strength of La Nina will increase to 60 percent and the possibility of El Nino strengthening again during this period is zero.
