Question

Cause of a cloudburst in points

Answer 1

Cloudbursts occur because the warm air current from the ground or below the clouds rushes up and carries the falling raindrops up with it.

The rain fails to fall down in a steady shower. This results in excessive condensation in the clouds as new drops form and old drops are pushed back into it by the updraft. Then one of them gives in. The air current slows down or the clouds can't hold.

The resulting violent downpour can dump as much as 70,000 tonnes of water over an acre of land.

In India, a cloudburst mostly occurs in the mountains of India where the low monsoon clouds are stopped by the high mountains. But it may happen elsewhere.

On July 26, 2005, a cloudburst over Mumbai dumped 1,448 mm of rain in 10 hours.

Answer 2

Cloudbursts happen because the hot air flow from the ground or beneath the clouds speeds up and moves the dying waterdrops up with it. The rain disappoints to fall down in a uniform shower. This occurs in extreme compression in the clouds as fresh drops form and old raindrops are forced back into it by the updraft.

Meteorologists say the storm from a torrent is normally of the shower type with a drop rate comparable to or higher than 100 mm per hour.

Generally, cloudbursts are correlated with storms. If these currents quickly cease, the entire quantity of water decreases on to a small area with catastrophic energy and creates mass destruction. This is due to a speedy crystallization of the clouds.

They occur most frequently in desert and mountain areas, and in inner areas of continental landmasses.
