MidLand, Jakarta – Even though it is a tropical country, Indonesia has experienced this several times Hujan is. So, what causes hail?
Reporting from bmkg.go.idhail is a phenomenon the weather present in nature. Hail events accompanied by lightning, thunderbolts and short-lived strong winds occur most often during transition or transition periods, both from the dry season to the rainy season and vice versa.
Hail also occurred in several areas in Indonesia. One of the most recent areas to experience hail is Sidoarjo, East Java, on Monday, February 26, 2024.
In subtropical areas that have four seasons, hail will fall during winter conditions with high temperatures. This is because the cold air surface temperature and high humidity prevent the hail from melting.
In tropical regions, however, including Indonesia, hail falls due to meteorological phenomena that have a horizontal impact over different periods of time.
Reporting from Itera.ac.id. Usually the most common cause of hail in tropical regions occurs because high humidity and unstable air masses together with surface air temperatures and upper tropospheric air temperatures support the growth of convective clouds.
During hail, the rain falls in the form of ice balls formed due to the convective processes of the thunderstorms produced by the cumulonimbus clouds. The appearance of these clouds is part of the hydrological cycle.
So, heat energy from the sun can evaporate seawater. Then, water vapor rises into the atmosphere and forms clouds at a certain height when the air temperature above becomes colder.
Cumulonimbus clouds are made up of small clouds that gather and transform into thick clouds due to gusts of wind. The clouds contain water, ice and electrical charges in the form of lightning. These clouds can reach the highest layers of the atmosphere due to their thickness.
Announcement
Reporting from British. Under certain conditions, cumulonimbus clouds will become saturated. The increasingly cold pressure and temperature mean that the ice grains of the cumulonimbus do not melt completely and may fall to the Earth’s surface. At that moment the hail occurred. Meanwhile, the size of the ice that falls during rain varies from about 5 millimeters to more than 15 centimeters,
A senior researcher at the Disaster Mitigation and Climate Change Research Center (Puslit MKPI) Sepuluh Nopember Institute of Technology (ITS), Amien Widodo, also provided a more detailed explanation about hail in Indonesia.
According to Amien the hail occurred due to very large and dark mushroom-shaped cumulonimbus clouds. These clouds can also bring very strong tornadoes. This condition aggravates the consequences of hail in Indonesia.
Seeing the massive climate change, Amien assessed that the hail could potentially become a natural disaster, having previously been only an ordinary phenomenon. Larger, denser hailstones can cause harm to people, such as breaking glass or tiles.
However, you need to pay more attention to tornadoes that accompany hail because they are destructive. Despite the clouds Cumulonimbus It doesn’t always bring tornadoes and hail, but people still need to be alert, especially during the rainy season.
