What is a cloudburst?
Cloudbursts occur when an air stream carrying a high warm temperature prevents saturated clouds from producing rain. Raindrops get larger and are propelled upward by the air current rather than falling. They eventually weigh too much to retain and fall, causing more rain than usual.

An example of a cloudburst
A cloudburst is defined as an intense downpour that lasts only a brief time and is occasionally accompanied by hail and thunder. It is defined by the India Meteorological Department (IMD) as unexpected precipitation that exceeds 100mm (or 10 cm) per hour across a region of land that is between 20 and 30 square kilometres. Floods can occur when there is heavy rain, like this.
In essence, all cases of cloudbursts entail heavy rain for a brief amount of time, although not all instances of heavy rain for a brief period meet this condition.
What happens during a cloudburst?
Cloudbursts occur when an air stream carrying a high warm temperature prevents saturated clouds from producing rain. Raindrops get larger and are propelled upward by the air current rather than falling. They eventually become too heavy to support and fall, causing more rain than usual. There isn't a real "burst," but rather an intensified version of a torrential downpour.
Why do clouds burst in mountainous regions like Amarnath?
There is little concrete information on the precise amount of cloudbursts that occur in India, according to experts, and it is challenging to anticipate when they will occur. Since its definition only applies to a relatively narrow area, it is challenging to foresee and recognise cloudbursts right away. However, due to the geography and altitude, they are more likely to appear in mountainous areas.
Why clouds burst became more frequent?
This is because the upward migration of the extremely warm stream of air prevents some saturated clouds that are ready to condense into rain from producing rain in mountainous places. Raindrops are transported aloft by the air stream and do not fall downhill. Existing droplets enlarge and new raindrops are created. After a while, the cloud can no longer support the rains, and they all fall to the ground at once in a sudden flash.
Can cloudbursts be predicted?
Cloudbursts are challenging to predict, although doppler radars can be useful in doing so. Doppler radars are specialised radars that produce velocity information about distant objects by utilising the Doppler effect. This is accomplished by sending a microwave signal at a target and measuring how the motion of the target affects the frequency of the returned signal.
There aren't Doppler radars in every part of the Himalayas, where cloudbursts are most prone to occur. The Himalayan region has seven doppler radars, according to Earth Sciences Minister Jitendra Singh, who stated this in the Lok Sabha on July 23. There are two in Jammu and Kashmir (Sonmarg and Srinagar), one each in Uttarakhand (Kufri), Mukteshwar (Uttarakhand), Mohanbari (Assam), Meghalaya (Sohri), and Tripura (Agartala). Only 34 radars are currently operational throughout the nation, according to Mohapatra, who previously spoke with India Today. Just 6 more have been added in the previous five years.
On the IMD website, it is also stated "Because cloudbursts occur on such a small scale in both space and time, it is very challenging to predict them. We need to have a dense radar network over the cloud burst prone areas or one needs to have very high resolution weather forecasting models to resolve the extent of the cloud burst in order to monitor or nowcast (predict with a few hours lead time) the cloudburst."
