In orographic rainfall, the windward slope of the mountain receives maximum rain and the leeward slope remains generally drier and is known as the rain shadow area.

When the condensation or solidification of the water vapor in the atmosphere occurs near the earth's surface, then  we can see fog, dew, frost etc. 

As hailstones are heavy, they fall towards the ground, but because of the frequent upward flow of air, they are repeatedly taken upwards. Here a new layer of snow encapsulates the hail. This happens quite a few times. Hence concentric layers are formed while the hail grows in size.

Because of the upward movement of air, the water droplets go to higher altitude and solidification of these droplets occur and hailstones are formed.

The precipitation where hail occur with rainfall, that type of precipitation is called as hail showers. Because of hail, crops may get destroyed and loss of life and property may also occur.

Hail do not occur in cold zones because of lack of upward flow.

Rain shadow area is associated with orographic rainfall. When the saturated air is obstructed by land form barrier such as mountain, it forced to ascend and as it rises, it expands and temperature falls. As a result, condensation takes place and rainfall occurs. In this type of presentation, the windward slope of the mountain receives maximum rain and the leeward slope remains generally drier and is known as the rain shadow area.  

Specific air formation when the pressure at an area is less than the surrounding regions. This is called cyclone. Air from the surrounding region comes towards the center of the cyclone and starts moving upwards.

In equatorial areas, the surface gets heated because of the sun's heat and the air near it also gets heated. As it gets heated, it spreads and becomes lighter and moves upwards.
