Study Links 70% of Winter Pollution Variation in North India to Western Disturbances
A study finds that about 70% of the year-to-year variation in winter air pollution across northern India is linked to the frequency of western disturbances—storm systems from the Mediterranean that bring precipitation and ventilation, reducing pollution levels. Winters with fewer such storms tend to have more severe pollution. Researchers also identified ocean temperature patterns in autumn as predictors of these disturbances, potentially enabling advance warnings and better preparation for pollution control during winter months.
