The process of the occurrence of hail can be explained scientifically. This phenomenon is also quite common in Indonesia.
Ironically, some people assume that the phenomenon of hail occurs due to mystical things. In fact, the occurrence of hail can science explain in detail.
Hail is different from snow. Hail events will occur during the transition from the rainy season to the dry season or transition.
The process of the occurrence of hail In Complete
Indonesia is a country with a tropical climate. This is what makes Indonesia only has two seasons each year, namely the rainy season and the dry season.
However, when the two seasons transition, they are known as transitions. During this transition period the weather conditions were more extreme than usual.
One of the impacts of the transition is hail events. Hail events have often occurred in several areas in Indonesia.

Of course, the phenomenon of hail does not occur suddenly. There is a process that eventually makes hail occur. Here’s the process:
- Thermal energy from the sun will make water in rivers, seas, and lakes undergo a process of evaporation and rise into the Earth’s atmosphere.
- Water vapor will rise and experience condensation or condensation process. At this stage the water vapor will become ice particles because the air temperature is low.
- The key to the process of hail formation is because of the mass movement up and down in strong clouds.
- The process of rising and falling air masses is very strong to form ice that continues to grow. When it gets bigger, the ice will no longer be able to rise to the top.
- Because of its large size, the ice will then fall to Earth before it successfully melts completely.
You need to know that the Earth has a layer of freezing or freezing level alone. In this layer, the Earth’s temperature will reach zero degrees Celsius.
Freezing level also of course different in each region. In Indonesia itself, freezing level located at an altitude of 4 km to 5 km above sea level.
Causes of Hail
Broadly speaking, hail occurs not much different from ordinary water rain. However, the main cause is a different freeze.
Freezing will occur in the process of condensation or condensation above the cloud. The condensation process will occur when the water vapor finally turns into ice particles.
Even in ordinary rain phenomena, this freezing process occurs. In the normal process, freezing will produce small ice grains.
However, the stage of condensation will be different in the process of hail formation. Condensation will occur suddenly so as to form ice particles with a size that is no longer small.

The size of the ice is much larger so that when it falls to Earth, the grains are still in the form of ice. Whereas in normal rain, small ice particles will melt after falling to the Earth’s surface.
Another cause of hail is the presence of Cumulo Nimbus clouds that produce rain. The clouds are towering and layered.
The color of the Cumulo Nimbus cloud is also very scary, which is gray. When there are clouds, there will certainly be heavy rain with lightning and strong winds.
Ice Rain is Different from Snow
Some people still mistakenly think that hail is the same as snow. It is very wrong because the two are very different.
The main difference is the process of the occurrence of local hail. This means that the hail will not be evenly distributed throughout the region.
More than that, hail is only a form of extreme weather on Earth because of the changing seasons that cause high air pressure.

Meanwhile, on the other hand, the phenomenon of snow is included in the season. There are only a few areas on Earth where snow can occur. Snow will also definitely occur in a certain period of time.
Another difference between sleet and snow is their shape. Hail will fall to Earth in the form of ice cubes. While the snow will fall to Earth in the form of white and soft like cotton.
That’s a scientific explanation of the causes and processes of hail. Hail can occur anytime and anywhere when the weather is extreme. (R10 / HR-Online / Editor-Ndu)
