Description of DTE: Science of torrential rain

Telangana Chief Minister said cloudbursts may be a ‘foreign consipiracy’ during his visit to flood-hid Bhadrachalam

India, especially Himachal Pradesh and Uttarakhand in the Himalayas, has been repeatedly devastated by heavy rains during the monsoon season. Flash floods in Uttalacand in 2013 killed thousands and are one of the worst natural disasters recorded since the 2004 tsunami. According to
meteorologists, climate change has made these extreme weather events more frequent and more intense.
In 2021, Himachal Pradesh recorded about 30 torrential rains and 50 Uttarakhand states, according to the South Asian Network on Dams, Rivers and People, a network of organizations working on related issues. SANDRP has collected data from news articles about these disasters.
There is no more this year. Flash floods struck near the Amanas Cave in Jammu and Kashmir on July 8, 2022, killing 17 people and injuring 40 by July 16. According to official information, more than 60 people are still missing. One of the first heavy rains of the year occurred on May 9 in the Budgam district of Jammu and Kashmir, killing at least one person.
A few days ago, a similar incident occurred in the Kuru district of Himachal Pradesh, which washed away about six tourists.
The Godavari River, inflated by constant rain, also caused floods in Telangana’s temple town of Bhadrachalam, killing at least 15 people last week, officials said.
Chief Minister of Telangana K Chandrashekarlao, who visited the flood-affected areas on July 17, quoted media reports that the repeated heavy rains were the result of a foreign conspiracy.
However, as experts suggest, he acknowledged that climate change could also contribute.
This brings us a question: why torrential rains occur?
Torrential rain is a sudden, localized heavy rain.
The India Meteorological Department defines torrential rain as a condition in which precipitation in a particular area exceeds 100 millimeters per hour.
They often cause flash floods, becoming more and more frequent from May to September, when many of the countries experience the southwest monsoon season.
The phenomenon that causes this large amount of precipitation in such a short time is “topographical rise”. Clouds that are already expected to rain are being pushed up by warm air currents.
At higher altitudes, the water droplets in the clouds grow larger and new water droplets are formed. Lightning in these clouds helps delay the rain.
These dense clouds will eventually burst and will no longer be able to retain large amounts of water. This causes heavy rainfall in the geographic area beneath and overflows the body of water in a very short time.
This phenomenon is more common in mountainous areas because it provides a terrain where moist air rises rapidly along the slopes of the mountains. The
Doppler radar system is ideal for predicting disasters, and since 2013 Uttarakhand has been called upon to equip surveillance stations in torrential rain-prone areas. The number of
stations equipped with technology is still small,
