As promised, today we are going to continue with the sixth topic i.e Cloud Bursts. Let us provide you the brief explanation of the said topic.
IAS Prelims 2017 Important Topics on Current Affairs: Cloud Bursts
Current Affairs is an extremely essential component of all major competitive exams. An aspirant who has a grip over General knowledge is always at an advantage, not just for written examinations but also interviews. Updating Daily GK will help you perform well in all the competitive exams.
Let us provide you the explanation of the given topic.
A cloudburst is short-term extreme precipitation that takes place over a small area; it is not, as is sometimes understood, the breaking open of a cloud resulting in the release of huge amounts of water.
Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and bursts into a public cloud when the demand for computing capacity spikes.
What Causes Cloud Bursts?
Cloudbursts are caused when updrafts fail. These updrafts contain massive amounts of water vapor traveling at high speeds so that when it fails, heavy rainfall results, which is a cloudburst.
Updrafts fail, resulting in cloudbursts for a number of reasons. One reason is that heat energy mingles with the water vapor. Sometimes cloudbursts result when clouds heavy with water vapor collide with a mountain.
Cloudbursts are intense but do not last long, which can create flash floods, according to the Chicago Tribune. This is especially dangerous in hilly terrain. India has a long history of cloudbursts and the ensuing disaster. For instance, in 1908, a cloudburst caused the Musi River to flood, killing 15,000 people. An entire village was destroyed because of a cloudburst in 1970. In 1998, a cloudburst caused a landslide in Malp that killed hundreds of peoples. In 2005, a cloudburst swelled a river by 37 inches in just a few hours, killing more than a thousand people in Mumbai. The Times of India reports that the instances of cloudbursts at Himachal Pradesh are increasing drastically. The danger lies in the region’s 249 glacial lakes and the devastation that would commence if those lakes were to be breached because of rapidly rising waters from cloudbursts.
How does it form?
- Generally cloudbursts are associated with thunderstorms. The air currents rushing upwards in a rainstorm hold up a large amount of water. If these currents suddenly cease, the entire amount of water descends on to a small area with catastrophic force all of a sudden and causes mass destruction. This is due to a rapid condensation of the clouds. They occur most often in desert and mountainous regions, and in interior regions of continental landmasses.
- They occur most often in desert and mountainous regions, and in interior regions of continental landmasses.
- The topographical conditions like steep hills favour the formation of these clouds in the mountainous regions. And also the devastations, as water flowing down the steep slopes bring debris, boulders and uprooted trees with great velocity damaging any structure that comes in their way.
- The Chhotanagpur plateau spread across north Odisha, West Bengal and Jharkhand is the world’s most vulnerable spot for formation of severest thunderstorms.
- Cloudburst can occur not only in the monsoon seasons but also during March to May which is known for severe convective weather activities.
Examples of cloudburst
- 2010 Ladakh Floods: A major cloudburst and heavy rainfall on the intervening night of August 6, 2010 triggered mudslides, flash floods and debris flow in Jammu and Kashmir’s Ladakh. 71 towns and villages in Leh were affected in the region and at least 255 people died.
- 2013 Uttarakhand Floods: The multi-day cloudburst in the hill state of Uttarakhand triggered flash floods and massive landslides.
- The large scale features, which are conducive for occurrence of severe thunderstorms associated with cloudburst, are predictable two to three days in advance. However, the specific location and time of cloud burst can be predicted in NOWCAST mode only, i.e. a few hours in advance, when the genesis of thunderstorm has already commenced. To detect these sudden developments, a Doppler Weather Radar (DWR), a powerful tool for time and location specific prediction of cloudburst, can be deployed a few hours in advance. Coupled with satellite imagery this can prove to be useful inputs for extrapolation of cloudbursts anywhere in India.
