Question

What causes the violence associated with torrential rain?

Answer 1

Hint:Heavy pouring rain refers to the torrential rain. Torrential as the name signifies refers to a ‘torrent’ which means violence or rapidity. The Latent Heat of Condensation is responsible for causing the violence associated with such kinds of rain. Torrential rains cause risk to human life, these result in damaging of infrastructure and crops and many more brutal consequences.

Complete answer:
The turbulent flowing streams or the extremely hard downpour refers to the torrential rain. The instability in atmosphere and moisture results in the torrential rain. When the vapor condenses into liquid water then it results in rain. For torrential rains the moisture content should be quite high. In warm weather conditions air is able to hold more moisture so global warming can also contribute towards heavy downpour. Rain is referred to “heavy rain” when the rate of water falling is $7\cdot 6$mm per hour or more than it. Heavy rains mostly occur in the Tropics because warm air can hold more moisture as compared to cold one and the tropics are generally attributed with high temperatures. There is a relation given by Clausius and Clapeyron which states that for every degree Celsius rise in Earth’s temperature the amount of vapor air can hold increases by about $6%$.
Torrential rains are known to release Latent heat of Condensation suddenly which results in the violence created by it. Latent heat is the hidden heat which is released or absorbed during the phase change at constant temperature conditions. Latent Heat of Condensation releases when atmospheric vapors condense into liquid droplets resulting in rain. Since there are a lot of vapors present in the atmosphere during torrential rains so they all condense into droplets then they are accompanied by the release of sudden energy which results in violence.

Note:
Torrential rains lead to flooding of rivers and other water bodies which results in destruction of infrastructure. Torrential rains are identified on weather radar by red, purple and white colors which indicate high precipitation. Precipitation is caused by the convective clouds when enough moisture content is present in them.
