YOGYAKARTA Hail is a weather phenomenon marked by falling hail and heavy rain, lightning, and strong winds. This phenomenon is reported to have just occurred in a number of parts of Indonesia, such as West Lampung, East Java: Sidoarjo, Bali: Tabanan, South Sumatra: Palembang, West Java: Tasikmalaya, to Depok. What causes hail?

According to the Meteorology, Climatology and Geophysics Agency (BMKG), there are a number of factors that trigger hail.

Usually, this extreme weather phenomenon occurs during transitions or transitions between the rainy and dry seasons.

"Escal rain is a weather phenomenon that often occurs in several areas during the transition of the season," said BMKG in an upload on Instagram, Monday, November 4, 2024.

Hail is marked by the fall of hail accompanied by heavy rain, lightning, and strong winds in a short time.

Based on weather monitoring carried out by the BMKG, in the last few days there has been an increase in rainfall in large parts of Indonesia, especially in the central and southern parts. This is different when compared to weather conditions at the end of October 2024, where weather conditions are dominated by hot weather and Terik.

"The increased atmospheric capacity is due to the reduced influence of the Tropical Cyclone Kong-Rey and the active waves of the Rossby Ekuator in Indonesia, such as Sumatra, Java, Bali, to Nusa Tenggara," said BMKG.

BMKG said that hail occurred because it was triggered by a significant pattern of connectivity in the atmosphere on a regional local scale.

This extreme weather phenomenon can also be formed from convective cloud systems such as Cumolonimbus (CB) which generally have a towering dimension.

In this cloud, water grains freeze due to the freezing temperature of clouds, even below -60 degrees Celsius.

Furthermore, when the convection process gets stronger, the ice grains that form become bigger. When the air is no longer able to withstand the weight of the ice grains, ice begins to descend to the surface.

"If the surface temperature is cold enough, these ice grains do not dilute and fall as hail," explained the BMKG.

Quoted from the official BMKG website, the phenomenon of hail can be known one day before the incident. The following are signs of hail that you need to know:
