Recently a natural threat peep in man’s psyche, this is not only the scientists of all regions but also every people. The name of the villain is Cloudburst, a natural calamity, which has a power to smash many people’s life in a moment. It is a threat as it overwhelm the whole area where its’ take place and slay a great number of people. Several suffered people face this terrific calamity and at the same time fortunate as they get their life back. But this horrible experience makes their life spoil for a time.
In this year on July, 1 in Uttarakhand cloudburst struck and more than 20 people died and many were homeless. In this year on 8th May incessant rainfall caused damage in Uttarakhand but fortunately no casualties reported. In 2014 cloudburst claimed almost 200 lives and over 1, 84,000 people were rescued. Now we can’t guess which region or which place is the next target in front of cloudburst.
Mass in the whole world bother about this sudden collision and the scientists try to predict this but it is very unfortunate to know that there are no acceptable techniques for forecasting the incidence of a cloudburst because of their small scale. Only the areas which receive heavy rainfall can be recognized on a short-range scale.
Consequently, this is a calamity which is unexpected and the cloudburst prone areas fear much in the mean time of monsoon (approximate time of cloudburst). At this instant many queries appear in various peoples’ wits about this sudden dread.
Now a question arises: What is Cloudburst?
A cloudburst is a high power rainfall, which normally last for few minutes but in this few minutes it successful to do its terrible job. It’s creating a flood like condition in the area. Actually it is an unpredicted very aggressive rainstorm falling for a short period of time limited to a small geographic area.
Sometimes the cloudburst is mixed with hail & thunder. Meteorologists (who study with atmosphere phenomena) say usually the rain is like shower type and when it fall, the rate of the rainfall may be 100 mm or above than 100. In a minute more than 2 cm rain may fall from cloudburst. They are called ‘bursts’ because it was believed earlier those clouds were concrete ample full of water. So, these violent storms were attributed to their bursting.
Cloudburst can suddenly dump 72,300 tons of water over one square acre. A real cloudburst is very rare. Luckily it doesn’t happen regularly. Sometimes we call a heavy shower in the mountain a cloudburst but actually it is not so. The overflow of the slop creates flood which seems that a cloud has burst open like a paper bag.
What causes a Cloudburst?
Cloudburst also coupled with thunderstorms. Most air mass thunderstorms consist of agglomerations of several thunderstorm clouds. The air current rushing upwards in a rainstorm which carry a large quantity of water and if the current cease suddenly the whole amount of water fall down on a small area with catastrophic force which causes a enormous devastation. This natural phenomenon is known as cloudburst. Cloudburst falls from very high altitude, so the force of cloudburst is so powerful. In real cloudburst does not break open as the rain which is in cloud, unable to fall down in a shower. When the cloud is ready for raining and the land of a particular area going to be hot and sometimes a hot air current moving under the cloud then it’s started a heavy rain.
Assuming that the rising motion and condensations are achieved, the initial stage, called the cumulus stage, of a thunderstorm cloud consists of an updraft throughout the cell. In the higher at a freezing level a mixture of ice crystals and water droplets exists. Then this beginner stage, ice crystals process of a rain formation. If the rain water developed and it forms in the upper portion of the cloud, the updraft is strong enough to prevent them from falling. When the load of rain drops increases then the updraft has no power to hold it in it, it begins fall down.
In the mature stage, the rain when it is falling down it is moved by the nearby air and a downdraft forms within the cloud. In its final stage, the cloud is characterized by sinking motion throughout, with only light rain at the surface. The success of the cloud in producing rain is responsible for its end; the downdraft spreads throughout the cloud. In a sense, the cloud collapses on itself, leading to a cloudburst.
Weather scientist Varun Joshi of Guru Gobind Singh Indraprastha University, Delhi said any rainfall above 120 mm per hour is forceful. But when this amount of rain or more than it falls in an hour or less, it is called a cloudburst.
Which places it’s mostly happen?
Mostly cloudbursts occur in the dry places like deserts and also the hill stations or mountainous provinces. Cloudbursts can also happen in the internal part of the country. In is seen during the monsoon. Himachal Pradesh is one of the cloudburst hit areas, as it’s placed in a higher altitude area. Also villages in those areas are suffered much, the natives lost their homes and possessions. The area devastated and many died.
