Why is Delhi in the grip of freezing cold?

Not only this, the intensity of the western disturbances that have come has been quite weak. Due to this, rainfall has also been 100 percent less than normal. This is why the people of Delhi are facing the triple attack of severe cold, dense fog and pollution.
