IMD Weather Update: Monsoon Arrives Early in the Country! Know When Heavy Rain is Expected, Impact of La Nina

IMD Weather Update, Monsoon 2024: Like every time after the summer, this time too people are waiting for the monsoon. It is being claimed that due to the effect of La Nina, it may come before time.

IMD Weather Update, Monsoon 2024: States facing the heat of summer may get relief from it soon. This time the monsoon may arrive before time and there are also chances of heavy rains. Although the Meteorological Department has not made its prediction regarding this, but according to experts, due to the simultaneous activation of the conditions of Indian Ocean Dipole and La Nina, the monsoon may arrive early this year.

These boundary events are creating a strong monsoon condition with potentially heavy rains in many parts of the country. According to a report by India Today, the La Nina effect is a recurring weather phenomenon that is caused by cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean and the Indian Ocean Dipole and fluctuations in sea surface temperatures in the Indian Ocean.

Reasons for early arrival of monsoon

These interconnected dynamics are anticipated to significantly impact the southwest monsoon. Most weather models suggest a positive IOD phase over the equatorial Indian Ocean that coincides with the formation of La Niña in the Pacific. The simultaneous existence of these events in the monsoon backdrop indicates that these factors could amplify the extreme monsoon conditions typically experienced from July to September.

Observations of the emerging La Nina conditions and the IOD event point to a westward shift in the main monsoon convergence zone. This triggers a response from the Arabian Sea near the Indian coastline, leading to large-scale upwelling that supports the prevailing monsoon system, leading to enhanced rainfall throughout the season.

What did Skymet say about La Nina?

At the same time, according to Skymet Managing Director Jatin Singh, ‘El Nino is rapidly turning into La Nina and, during La Nina-related years, the monsoon circulation becomes stronger.’ IMD officials had said earlier this month that La Nina conditions associated with favorable monsoon in India are likely to be established in the latter half of the season.
