The Central Government’s Air Quality Early Warning System for Delhi noted that “air quality of Delhi is going to improve significantly on Saturday and Sunday due to better ventilation conditions and rainfall”.
According to the report of The India Meteorological Department, it stated that the nation’s capital and its neighboring states will receive light rainfall on Friday and Saturday due to the influence of the current Wester Disturbance passing over The Himalayan Range. It is predicted that the maximum wind speed will be 15kmph favorable for the distribution of pollutants.
“After the Western Disturbance withdraws, icy cold northwesterly winds blowing from the snow-laden Himalayas will bring temperatures down in the plains,” the IMD quoted.
What about climate change in Delhi?
The IMD forecasts that “It is expected that the minimum temperature will drop to 8 degree Celsius by Monday”. The capital has recorded a minimum temperature of 10.9 degrees Celsius today The maximum is hoped to settle around 29 degrees Celsius.
Calm winds and low temperature will entangle pollutants close to the ground and high wind speed will help in dispersion.
