Why do clouds burst on mountains: Reports of cloudbursts are common during monsoon every year in hilly areas of India. This incident is often seen in states like Uttarakhand, Himachal Pradesh and Jammu and Kashmir, due to which there is a loss of heavy life and property. Life gets disturbed, the roads break, and sometimes the whole village falls into its grip. Recently, a sudden cloudburst in Kullu in Himachal Pradesh created a severe flood -like situation. But have you ever wondered why there is a cloudburst in the mountains itself? How do clouds burst? And is there any truth in this that a lot of water falls on the ground only once from the sky when cloudbursts occur? Let us know the answers to all these questions in detail.
What is cloud bursting(What is cloudburst?)
First of all, it is important to understand what is the cloud burst. This is not an incident in which a cloud burst. In the language of science, cloud bursting refers to an extremely acute rainfall. According to the Indian Meteorological Department (IMD), when an area receives 100 mm or more rainfall per hour, it is considered a cloud. This is often for limited time in a small geographical area. It distinguishes it from normal rainfall, its intensity and its effect in limited areas.
Causes of cloudburst (Reasons for cloudburst)
Now let’s talk about cloudburst. Many factors are responsible for cloudburst:
1. Summer and Moisture: The hot and moist air rises up and cools the clouds. When there is excessive moisture in the air, large cumulonimbus clouds are formed, which are responsible for heavy rains.
2. localized convection (Localized Convection): The complex topography of the mountains gives rise to acute convection streams locally. These currents raise moisture within the clouds rapidly, which increases the amount of water in them.
3. Effect of gravity: When the amount of water in the clouds becomes so high that they do not stop it further, it suddenly falls and falls in large quantities due to gravity. It feels like falling a lot of water simultaneously, but it is not like a cloud burst, but rather extremely intensified rainfall.
Why clouds burst in the mountains(Why cloudbursts happy only in mountains?)
The main reason for this is “Orographic Lift”. In the plains, there is no obstruction like mountains to rise up the air, causing moisture air to rise gradually and rain is normal. At the same time, the steep slopes of the mountains push the air -laden air rapidly up, causing water deposition in the clouds very fast and they suddenly fall down as heavy rainfall. In addition, the narrow valleys and complex terraces of the mountains also cause rapid flow of water and floods, causing the damage to increase the damage.
