About Western Disturbances

  • These are east-moving rain-bearing wind systems that originate beyond Afghanistan and Iran. Pick up moisture from as far as the Mediterranean Sea and even the Atlantic Ocean.
  • Extra-tropical cyclones, which are a result of the interactions between polar and tropical winds, form low-pressure areas.
  • The westerlies drive a non-monsoonal precipitation pattern that is more frequent and stronger during the winter season.

Western Disturbances are important weather systems that play a significant role in the weather patterns of the Indian subcontinent, particularly during the winter months. These disturbances are associated with the movement of low-pressure systems from the Mediterranean region towards the Indian subcontinent, bringing rain, snow, and strong winds to various parts of the region.

Western Disturbances are crucial for the precipitation and water resources of several regions, including northern India, Pakistan, Nepal, and parts of Afghanistan. They contribute to the winter rainfall and snowfall, which is vital for agriculture, hydroelectric power generation, and maintaining the ecological balance of these areas.
