Where is the heaviest rainstorm?

In some parts of the world, rain often pours down, causing disasters. The rainstorm mainly occurred in tropical and temperate regions.

Thunderstorm is a widely distributed weather phenomenon. When cumulonimbus clouds develop strongly, they are often accompanied by thunderstorms-dark clouds rolling in the sky, lightning and thunder, and sometimes violent storms.

Thunderstorms can be divided into three types: thermal thunderstorms, topographic thunderstorms and frontal thunderstorms. In tropical and temperate summer, the sun shines directly, and the lower atmosphere is heated and expanded, forming strong convective air and producing thermal thunderstorms. The mountainous terrain is complex and prone to air convection, cumulonimbus clouds, cumulonimbus clouds and thunderstorms. In winter and spring in the northern hemisphere, cold air collides with warm air southward, and the warm air rises strongly, resulting in thunderstorm weather.

Thunderstorms on earth occur more than 6.5438+0.6 million times a year on average, about 50,000 times a day. The most violent thunderstorm activity occurs in equatorial belt and tropical area.

Java has the most thunderstorms in the world, with 60% thunderstorm days in a year. However, the number of thunderstorm days varies from place to place on the island, such as Jakarta, with an annual average of 133 days; In Bogor, there are an average of 322 lightning days and showers every year, accounting for 88% of thunderstorm days in a year. People praised it as the "Leidu" of the world.

Bogor is located near 4 south latitude, and there are many towering volcanoes nearby. The hot and humid air mass blown from Java Sea is blocked by mountains and rises sharply, which is easy to form convective rain. The annual precipitation is as high as 4618 mm. The daily weather changes in Bogor are very regular: the weather is clear in the morning, the cumulus clouds in the sky thicken in the afternoon, the lightning and thunder thundered in the afternoon, and the rain poured down. After the rain, the air was fresh and the whole city was bathed in the scorching sun.

The average thunderstorm in China is in Dan County, Hainan Island, with thunder rumbling on average every year 130 days, and thunder can be heard in winter.

However, the place with the heaviest rainstorm in the world is reunion island in the Indian Ocean. Heavy rain falls from the sky like a waterfall. People in the rain, I see a large water curtain around them, and I can hardly see anything. The flash floods rolled and the river burst. The heavy rain killed birds, destroyed trees and houses, flooded fields and washed away rocks. March 1952, 1 ~19 lasted 8 days and nights, and the four highest rainstorms in the world were recorded in Cyprus, reunion island:1,1870mm, 22450mm and 43504mm.

Why does Reunion become the center of heavy rain in the world? It turns out that reunion island has a typical maritime climate and is located in the Indian Ocean. Tropical storms have struck many times and there is abundant rainfall. The snowy mountain on the island is 3069 meters above sea level. The storm brought a lot of water. When blocked by high mountains, the airflow rises sharply. When the hot and humid air is cold, it becomes a rainstorm on the windward slope.
