New Delhi: According to data from the Ministry of Earth Sciences, India has seen an increase in ‘extremely heavy’ and ‘very heavy’ rainfall events since 2012.
According to the data, 185 weather stations across the country reported ‘extremely heavy’ rainfall in 2010, but this increased to 341 in 2020, a nearly 85 percent increase.
In 2019, approximately 554 stations reported ‘extremely heavy’ rainfall, the most since 2012.
Rainfall less than 15 mm is considered ‘light,’ rainfall between 15 and 64.5 mm is considered ‘moderate,’ rainfall between 64.5 mm and 115.5 mm is considered ‘heavy,’ and rainfall between 115.6 mm and 204.4 mm is considered ‘very heavy.’
According to the IMD, anything above 204.4 mm is considered ‘extremely heavy’ rainfall.
The Southwest monsoon occurs in India from June to September and is considered the main rainy season for the Indian subcontinent.
During the 2020 monsoon season, rainfall events ranging from ‘heavy’ to’very heavy’ and ‘extremely heavy’ occurred across the country.
Flooding occurred in parts of Himachal Pradesh, Maharashtra, Kerala, Uttar Pradesh, Assam, Bihar, and Telangana as a result of such events.
The National Disaster Response Force (NDRF) rescued and evacuated 19,241 people and 334 animals by 2020.
West Bengal had the highest number of deaths due to heavy rains and floods, with 258 people killed. It was followed by Madhya Pradesh and Gujarat, both of which reported 190 deaths.
According to the Ministry, several scientific studies have found a possible link between climate change and the sudden occurrence of rainfall and temperature extremes.
This year, the monsoon arrived two days earlier than usual in Maharashtra and Goa.
The India Meteorological Department (IMD) also stated that the monsoon moved quickly across most of the country. It covered the majority of India in just ten days, owing primarily to active monsoon circulation and the formation of a low-pressure area over the Bay of Bengal.
Because of the approaching mid-latitude westerlies, the monsoon’s progress over the remaining parts of northwest India is expected to be slow, according to the IMD.
