Quora News: The torrential rain in Islamabad is being interpreted as a cloud burst. But people want to know what cloudburst is.
How did Cloud Burst Happened?
According to a statement issued by the Pakistan Meteorological Department, cloud bursts are also called rain gush and rain gust. If there is a short interval of heavy rain in a small area, it is called cloud burst.
For this, it is necessary to record at least 200 mm of rain in an hour in a specific area, but today no area of Islamabad has recorded more than 121 mm of rain in one or two hours. Cloud bursts also generate unusual lightning and thunderstorms. That’s why today’s event is not a cloud burst.
On the other hand, according to the Encyclopیاdia Britannica, a cloudburst is a local event that occurs for short periods of time and causes thunderstorms and intense electrical activity.
It usually raises the air below the clouds and prevents water droplets from falling for a while. Now as the air pressure decreases, a large number of waterfalls from the cloud and the water in the clouds flows as if the bucket has been overturned.
Also, keep in mind that most cloud bursts occur in mountainous areas. When large amounts of the waterfall, flooding occurs and its flow can cause great damage to populations and crops. According to the Meteorological Department, if an area receives 200 mm of rain in an hour, it can be called a cloud burst.
Today, the E-11 area of Islamabad was hit by heavy rains and people there have described the torrential rains as cloudbursts, but according to the Meteorological Department, no cloudburst has occurred in Islamabad.
The Meteorological Department said in a statement that on Wednesday, July 28, 2021, between 4.30 am and 7.30 am, 123 mm in Syedpur, 101 mm in Golra, 19 mm in Bokra, and 29 mm in Shamsabad. And 15 mm of rain has been recorded in Chaklala.
Talking to QUORATV, Sardar Sarfraz, Chief Meteorologist, Karachi Meteorological Department, said that today’s rain was forecast for May 26 by the Meteorological Department. However, Sardar Sarfraz said that at present the monsoon rains have received more than 3% of the forecast which is a normal occurrence.
However, he said that Pakistan is currently one of the top countries in the world in terms of climate change and two phenomena are prominent here, firstly the average temperature is rising and secondly, the normal rainfall pattern has been severely affected which is called ‘Eritic Pattern’.
He said that some meteorological stations in Pakistan are even older than Sosal from which the data obtained shows that the average temperature in the country is increasing.
