JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) said the potential for extreme weather such as hail, heavy rain and tornadoes could still occur until March-April due to transitions. and the impact that can be caused," said BMKG Deputy for Meteorology Guswanto in a statement received in Jakarta, Tuesday, February 22. Extreme weather events in the form of hail phenomena have occurred in the past week in several areas such as Surabaya, Lampung, Bekasi, and others. The incident was also accompanied by heavy rains of short duration accompanied by lightning/lightning and strong winds. The phenomenon of hail is one of the extreme weather phenomena that occurs on a local scale and is characterized by the presence of droplets of ice falling from the clouds and can occur over a period of time. a few minutes.

The phenomenon of hail can occur because it is triggered by a convective pattern in the atmosphere on a significant local-regional scale. Hail can form from a Cumulonimbus (Cb) type of convective cloud system which generally has towering dimensions which indicate that there is significant air lability in the system. the cloud so that it can form ice grains in the cloud with a size large enough. The size of the dimensions of the ice grains and the strong flow of air going down in the CB cloud system or what is known as a downdraft can cause ice grains with a size large enough that are formed at the top of the Cb cloud to fall. to the bottom of the cloud until it comes out of the cloud and becomes a hail phenomenon. The significant "downdraft" speed of the Cb cloud can cause the ice grains that come out of the cloud to not melt quickly in the air, and even when they fall to the earth's surface they are still in granular form. ice, known as the phenomenon of hail, said Guswan to.
