BMKG Makassar Urges The Public To Be Aware Of The Increase In Rainfall Due To The La Nina Effect

MAKASSAR - The Office of the Meteorology, Climatology and Geophysics Center (BMKG) Region IV Makassar appealed to the public to be aware of the increase in rainfall as an effect of the La Nina phenomenon in Indonesia, including South Sulawesi and West Sulawesi.

"What needs to be watched out for is the potential for increased rainfall during the rainy season, especially in the months where the peak period of the rainy season will enter, namely December 2021 and January 2022," said BMKG Region IV Makassar Foreman, Esti Kristantri, quoted by Antara, Friday, November 12. .

He explained that La Nina generally will have an impact on increasing rainfall and risk increasing the chance of hydrometeorological disasters such as landslides, floods, flash floods, strong winds, tornadoes, fallen trees and others.

In addition, the La Nina phenomenon is a natural phenomenon that causes the air to feel colder or experience higher rainfall. This phenomenon occurs when the Sea Surface Temperature (SML) in the central Pacific Ocean experiences cooling to below normal temperatures.

This causes the warm water mass to be carried towards the Western Pacific. As the warm water mass moves, the colder water under the Pacific Ocean will rise to the surface to replace the warm water mass that moved earlier.

"This is called upwelling and makes the sea surface temperature drop. This condition will increase rainfall in Indonesian territory, and make the rainy season last longer," he explained.

Therefore, La Nina is one of the factors that causes the rainy season in Indonesia to occur in addition to the monsoon winds.

The supply of air mass flows from the Pacific Ocean to the Indonesian Archipelago, and results in an increase or increase in rainfall.

Because it will increase the formation of rain clouds with additional wet air mass. Where in the end this will increase the potential intensity of rainfall.

"The BMKG appeals to the public to remain alert to weather changes. The public is advised to monitor climate developments and the latest weather," he added.

BMKG also opens 24-hour weather and climate information services via https://www.bmkg.go.id, social media @infoBMKG;, BMKG call center (196) BMKG Info application, or you can directly contact the nearest BMKG office.
