Nagpur: While Monsoon is considered the cleanest season, with relatively low air pollution, experts say air pollution is likely to reduce Southwestern Monsun’s rainfall by 10% -15% for the entire country.
The latest analysis by climate trends highlights the adverse effects of air pollution on the performance of the rainy season in India.
The analysis stated that as a peak of pollution in the coming years, the rain of monsoons can reduce at least 10% or even more, scientists said.
“Some places might even see rain reduced by 50%.
While there are consensus in all scientific communities that increased air pollution levels will reduce rainfall substantially in the coming years, it might also produce an unstable monsune pattern.
For example, we Maybe see extreme weather events such as severe ice hail, heavy rain along with an increase in the number of dry days, especially in more polluted places, “said analysis.
According to experts, air pollution is the result of suspended particles or aerosols in the atmosphere of anthropogenic emissions sources along with natural dust.
“This will also have an impact on the dynamics of the monsoon, for example the delay of onset.
Air pollution does not allow land to warm up to the necessary level.
Because of the pollutant, land heating occurs at a slower level,” said Dilip Ganguly, Associate Professor at the Atmospheric Science Center, Delhi Indian Technology Institute (IIT).
Said that the strong latitude and vertical gradient in aerosol would cause a gradual reduction in the Southwest Monsoon the average rainfall, SN Tripathi, Head of the Department of Civil Engineering in IIT Kanpur said, “The most affected place will be more pollution level.
This is very non-linear, because it is the result of the interaction between meteorology and aerosol.
Southwest Monsun is driven by the difference between soil temperature and the temperature of the sea.
The presence of large-scale aerosols over the mainland India will lead to ground-surface dimming.
The whole process will lead to weakening the monsoon dynamics, Which might even include the late on the emergence of monsoon.
“Tripathi is also a member of the Steering Committee from the National Clean Air Program (NCAP).
The next analysis added that although air pollution had an impact on rainfall in the country, the Indo-Gangetic plains seemed to be in a narrow place.
“From March to May, the ground surface is heated, because the strength of the inversion layer is reduced, reduced the level of pollution.
However, during that time, the dust of the West Rajasthan and the desert area side by side in Pakistan began transporting Indo-Gangetic plains.
This, along with local emissions , leads to increased summer pollution.
Also, the geography of the northwest plains including Delhi-NCR also does not support.
The entire Himalayan region keeps the indo-gangetic plain, which does not allow pollutants to escape and act as a barrier, “Krishnan Raghavan said, scientist at Indian Tropical Meteorology Institute, and the Main Author on the Intergovernmental Panel in Climate Change (IPCC) Report of Work Group 1.
Rain, Rain Loss – Air Pollution It is likely to reduce Southwest Monsun Rainfall by 10% -15% for the country – Some places may see rain Reduced by 50% – maybe witnessing extreme weather events such as heavy rain rain, heavy rain b Eva with an increase in the number of dry days – most of the affected places will be an area with more pollution levels – pollutants remain trapped in the Indo-Gangetic plains
Air pollution can reach 30% monsoon rain
