Factors affecting ranifall are:-

Evaporation-

The availability of water on the earth surface. In deserts there is no water so there is no evaporation.

Upliftment and Cooling-

The upliftment of water vapor can be achieved by different mechanism like by mountains or by the Cold fronts pushing the warm front above in mid latitude area or the intensive warming of earth surface causes the upliftment in low latitude area.

The upliftment from different types affect the rainfall pattern i.e. How much rain will fall, in what duration, in what quantity etc.

Condensation-

The speed of condensation decides the amount of water which is going to pour down. And temperature of condensation decides the from of precipitation e.g. snow, hail or rain

Aggregation-

This process is the least known process. Due to some less known mechanisms involving vapor pressure and others, the water droplets starts colliding with each other. So no aggregation no rainfall.

Precipitation-

If the temperature of earth surface is high then the rain gets evaporated before coming to surface.

A western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.[1][2] It is a non-monsoonal precipitation pattern driven by the westerlies. The moisture in these storms usually originates over the Mediterranean Sea, the Caspian Sea and the Black Sea.[3][4] Extratropical storms are a global phenomena with moisture usually carried in the upper atmosphere, unlike their tropical counterparts where the moisture is carried in the lower atmosphere. In the case of the Indian subcontinent, moisture is sometimes shed as rain when the storm system encounters the Himalayas. western disturbances are more frequent and strong in winter season.
