Cloudburst - Know what this unprecedented event is, when and under what circumstances it occurs?: Today we will talk about what is a cloud burst, why it happens and the various events related to cloud burst.

What is Cloudburst?

In the event of a cloudburst, an extraordinary amount of rain falls in a very short time. Simply put, 10 cm in an hour. If it rains, this huge form of rain can be called a cloud burst. It is also called cloud burst or flash flood.
It is believed that cloudbursts usually occur at an altitude of 15 kilometers above the earth's surface. According to the Indian Meteorological Department (IMD), an estimated 20-30 sq km of geographical area receives rainfall in this condition at a speed of 100 millimeters (MM) per hour.

The weather related factors behind the cloudburst incident in Kedarnath area were studied in detail. The study took into account atmospheric pressure, atmospheric temperature, rainfall, water content in clouds, collisions between clouds, cloud circumference, maximum cloud size, wind speed and direction as well as other parameters related to humidity. Also included was the maximum level covered by the cloud in low temperature and slow wind conditions.

In case of cloudburst, crores of liters of water are pumped out of the cloud at a certain place, i.e. more than 2 cm of rain falls in a few minutes, causing heavy flooding.

Why does the cloud break?

In our country, water-filled clouds usually move northwards, which is why the Himalayas are a barrier to clouds. In these circumstances most of the cloud bursts occur from these areas.

When a moist cloud freezes in one place. The water in it seems to mix with each other. Stabilization in one place greatly increases the density of the cloud due to the load of water. Then the heavy rain with the thunder breaks together.

Clouds cannot tolerate heat at all if we talk about cloudburst conditions in the plains. Even if hot air touches the cloud, the cloud is likely to break. On July 26, 2005, the clouds in Mumbai erupted not because of any obstruction, but because of hot air. Mumbai received about 57 inches of rain in 10 hours.

Some types of clouds

They are divided into several categories based on the shape of the clouds and the height above the ground. In the first category, low clouds are closer to the earth. Its height is about two and a half kilometers. These cloud appearances include brown clouds in terms of color, cumulus clouds, cumulonimbus clouds, brownish-black straight clouds, and brownish-white clouds.

The second category includes medium height clouds. Its height is from two and a half to one and a half km. There are two types of clouds in this class, one is Altostratus and the other is Altocumulus.

Clouds belonging to the third category are located at an altitude of more than 4.5 km. It consists of a fibrous i.e. Cirrostratus cloud.

Of these, cumulonimbus clouds are believed to be responsible for cloudburst. This cloud is very beautiful in appearance. The length of this cloud is up to 14 kilometers, when the humidity in such clouds suddenly stops or the wind enters the cloud, the color of the white cloud changes to black, causing heavy rain with heavy thunder. . There is so much rain from this cloud that it seems as if a river is flowing from the sky.

Events caused by cloudburst

The catastrophe took place at Kedarnath in Uttarakhand on June 16 and 17, 2013. Such a situation arose due to the cloud burst. Due to this, the river Mandakini was flooded due to heavy rains in Kedarnath Dham.

On July 18, 2009, Karachi, Pakistan was flooded due to cloudburst. At that time 250 mm of rain fell in just two hours.

On August 6, 2010, a series of cloudbursts erupted in the city of Leh, Ladakh, killing 115 people.
