La Niña could bring heavy rainfall in December-January

New Delhi. Two global models indicate that India could receive good rainfall during December-January due to the influence of the La Niña weather cycle. Conditions have become favorable for its origin in the Pacific Ocean. It's worth noting that La Niña often brings rainfall, while El Niño, on the other hand, is expected to cause drought.

The Australian Bureau of Meteorology and the US Climate Prediction Center predict that the La Niña weather cycle could arrive in the first half of December this year, remain active during December-January, and then end by the end of February.

According to the Australian Bureau of Meteorology (BOM), current models indicate that water temperatures in the tropical ocean could reach La Niña-generating levels between September 23rd and December 23rd, and remain neutral between December and February.

Surface water in the Pacific Ocean may cool further in the coming days, creating ideal conditions for the development of La Niña during the summer.

These ideal conditions still exist, but the intensity of La Niña is low. This intensity may increase in December. This impact will likely lead to torrential rains and floods in many Asian countries, especially India, which could prove detrimental to Rabi crops.

Rabi crops are sown mostly between October and December, and this process continues into January. By December, the harvesting of Kharif crops, except for paddy, pigeon pea, and castor, is complete, so there is no risk of significant damage to them.
