Kolkata: The level of pollution in the city can change to worse this winter compared to it in other years due to La Nina’s effect, which is expected to blow East India and India between December 2021 and February 2022.
La Nina, La Nina, Ocean and The atmosphere of phenomena, cooler partners of El Nino, will make the spread of suspended particular partics material in the air that is far more difficult, leading to a prolonged urban smoke fog.
Track the level of pollution in your city that complicated relationships between La Nina and air pollution.
With La Nina second in a row, the entire North Indian will face tight cold weather this season.
Meteorologists have a low-temperature record forecast across the Indo-Gangetic (IGP) plains, with December expected to be cooler than usual.
A recent report by Bloomberg predicts the temperature in India can fall to as low as 3 ° C in several northern regions in January and February.
With a temperature drop – and other factors, such as wind speed slowing down and regulating the fog – the level of pollution in Kolkata will definitely rise.
“Sustainable cloud cover and wind movement falls below 2M / sec making a recipe for a stable increase in pollution.
In addition, the movement of Transboundary pollution is very worrying.
We need to have mitigation measures for the entire area than only the city,” said Kalyan Rudra, “said Kalyan Rudra, Chairman of the West Bengal Polution Control Board.
There was a prediction that La Nina was estimated to be around December 2021-February 2022.
The second prevention of La Nina consecutive after 2020 can last until the beginning of spring 2022.
It transports cold air on Indian continental children from Sibernia and South China.
Strong current as long as La Nina pushes water towards the west and cools the surface of the sea, said the nimatology of Nairwita Bandyopadhyay ..
Climate trends, strategic communication initiatives with comprehensive climate ambitions and quotes experts on the long-term impact of La Nina on air quality around the city -The city like Delhi, Lucknow and Kolkata.
“There is a possibility of the second LA Nina back-to-back which can lead to cold from December 2021 – February 2022.
The phenomenon of the ocean is expected to reach this period.
Although there is no rule book, with the El Niño-South oscillation is getting colder than the previous estimate, trust This estimate has grown late.
But it must be noted that winter estimates are influenced by other factors of other parts of the world too, “said GP Sharma, President, Meteorology and Climate Change, Skymet Weather.
Winter temperature inversion contributes to fog accumulation.
Inversion occurs when cold air is stuck under a layer of warm air.
Because cold air cannot rise above warm air, pollution is built in cold air during temperature inversion.
Warmer air near the surface rises, allowing pollutants to disperse the atmosphere.
