Why peshwar and quetta receives more of its rainfall in winter?

Peshawar and Quetta receive more of their rainfall in winter primarily due to their geographical location and the influence of the Western Disturbances. These weather systems, which originate in the Mediterranean region, bring moist air and precipitation to the region during the winter months. Additionally, the Himalayas block moisture-laden winds from the southwest, funneling winter precipitation towards these areas. Consequently, the winter months become the peak period for rainfall in both cities.
