La Nina seemed to have played a critical role in influencing the countrys weather in 2020 which was a second consecutive year of above normal rainfal. The La Nina weather pattern causes frigid winters in the northern hemisphere.

El Nino is more frequent than La Nina. Earlier in the year while issuing its Long Range Forecast for South-West Monsoon 2021 on June 1 the IMD had said. It is likely to hound parts of India with extremely cold winters.

Generally El Nino and La Nina occur every 4 5 years. This change in the oceans temperature impacts the weather across the world. Temperatures in India are expected to fall to as low as 3 degrees Celsius 37 Fahrenheit in some northern areas in January and February.

As La Nina threatens to disturb global weather patterns the effects are visible as India witnessed the seventh-most delayed monsoon retreat this year since 1975. It is characterised by the unusual cooling of the central and east-central equatorial Pacific Ocean. Such events occur every two to seven years on average but they dont occur on a regular schedule.

It also means that the cooling of the first-year La Nina event of 2020 continues to evolve and may last till early spring of 2022.
