Western disturbances are low-pressure systems (disturbances) that flow from west to east (western winds) under the influence of the westerlies.
Disturbances are low pressures that are formed over the Mediterranean Sea that travels over Iran, Iraq, Afghanistan, and Pakistan carrying a good amount of moisture in the winter season.
Western disturbances emerge over the Mediterranean Sea as extra-tropical cyclones.
These moisture-laden depressions or disturbances finally hit the Himalayas and fall over as precipitation in the form of rainfall and snowfall.
