Cloud bursts are brief bursts of heavy rain that are both local and abrupt in character. This category includes rainfall of more than 100 mm or 10 cm per hour across a 20 to 30 square kilometre area. A geo-hydrological hazard is characterised as cloudburst. Nature’s ferocity and the extent of damage caused by rainfall may be frightening at times. Cloudburst occurs in India during the South-West Monsoon, which begins in June. Cloudburst is difficult to anticipate since it arrives quickly with devastating force, causing massive losses due to floods and erosion.
It happens mostly in mountainous places when warm air currents ascend from the earth and reach the sky. It picks up the rains as they fall. As a result, the rain does not fall steadily, and the clouds contain high condensation. At high altitudes, there is also a significant buildup of water. Warm air from below slows the fall of water. The upstream current weakens, and the waterfalls form in a single length.
The upward flow of air provides the necessary energy for the deluge. Cloudbursts often occur at elevations ranging from 1000 to 2500 metres above sea level. Cumulonimbus clouds are to blame for the heavy rain. Smaller droplets of water agglomerate with smaller ones in cloudbursts, resulting in the Langmuir precipitation process (the process in which large droplets of rain coagulate with tiny droplets of rain, which fall down slowly.)
The magnitude of a cloudburst’s impact is determined by the amount of devastation it causes to persons and property. It is impossible to anticipate the cloudburst with precision. Continuous and strong rainfall can cause deadly flash floods. It also produces debris flows, mudslides, flooding, mass movements, drownings, road closures, and cloudbursts.
Cloudbursts in mountainous terrains may be deadly, causing immense harm to life and property since the majority of the water congregates in valleys and gullies. It has the potential to harm the local flora and animals as well as public services.
Because of the production of low-pressure zones, it occurs in high-altitude places such as hills and mountains. These low-pressure zones cause clouds to collect with considerable power on the tops of mountains, resulting in orographic precipitation. A cloudburst can produce larger drops of rain up to 5 cm in diameter.
Cloudburst occurs in India in states such as Himachal Pradesh, Uttarakhand, and Jammu and Kashmir. It is a typical occurrence in Himalayan regions, particularly in the Garhwal and Kumaon Himalayas. They are most severe during the monsoon season.
It happens in high-altitude places such as hills and mountains because to the creation of low-pressure zones. These low-pressure zones encourage clouds to build on the tops of mountains, resulting in orographic precipitation. A cloudburst can produce larger raindrops of roughly 5 cm in diameter.
Cloudburst occurs in Himachal Pradesh, Uttarakhand, and Jammu & Kashmir in India. It is a typical occurrence in Himalayan locales, particularly in the Garhwal and Kumaon Himalayas. They are most severe during the monsoons.
Doppler radar, which is used for weather forecasting, may also identify the probability of a cloudburst. A cloudburst can be forecast six hours ahead of time. However, they are pricey. Identifying places of excessive rainfall might help you avoid danger and minimise damage. Low-lying region occupation should also be minimised.
Rainfall happens when moisture from the sky evaporates, condenses, and precipitates. Cloudbursts are brief periods of torrential rain. Cloudbursts do not always occur with rainfall. Cloudbursts are defined as rainfall rates above 100 mm per hour. Cloudburst is a quick, powerful, and devastating event. Rainfall and cloudbursts differ solely in the amount of rain received.
The NDMA is the country’s apex disaster management body. It is led by India’s Prime Minister. It was founded on September 27, 2006. Established in accordance with the National Disaster Management Act of 2005. Deals with national disaster mitigation, prevention, preparedness, and response. Creates rules, strategies, and procedures for disaster management.
There is no conclusive evidence that cloudbursts are becoming more often as a result of climate change. However, as we have seen, the frequency of severe rainfall events in a short period of time has been increasing. That implies that even during the rainy season, the wet episodes are highly wet and are alternated with extended dry intervals.
