Types of Rainfall

Convectional rainfall.

Orographic or relief rainfall.

Cyclonic or frontal rainfall.

Convectional rainfall : Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it. This causes the air to expand and rise. As the air rises it cools and condenses. ... If this process continues rainfall will occur.

Orographic or relief rainfall : Orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range. As the air rises and cools, orographic clouds form and serve as the source of the precipitation, most of which falls upwind of the mountain ridge.

Cyclonic or frontal rainfall : Frontal (or Cyclonic) Rain is caused by cyclonic activity and it occurs along the fronts of the cyclone. It is formed when two masses of air of different temperature, humidity and density meets. ... As the warm air rises, it cools, and the moisture present in it condenses to form clouds altostratus clouds

Explanation:

The three types of rainfall are as follows:

> Convectional rainfall: It is typical of warm moist air by heating from the ground surface. As a result of heating of the surface air, the air expands and forced to rise to great height. As the air rises, it cools and becomes saturated and dew point temperature(the temperature at which water vapour in the air condense(gas-liquid)) is attained and then clouds will form. By further cooling, precipitation takes place.

> Cyclonic/Frontal rainfall: This type of precipitation associated with a cyclonic activity and occurs along the frontal zone (front is a narrow zone of transition, dividing two air masses of differing temperature and humidity characteristics, intersecting the earth's surface. Fronts are most clearly developed in areas where are masses converge) of convergence particularly at the ITCZ (inter tropical convergent zone) and at the polar fronts.

> Orographic/Relief rainfall: It occurs when large mass of air is forced to rise across landform barriers, such as high mountain ranges, plateau, escarpment, or over high hills. the leeward side of such mountain barrier where the air is ascending and warming are characteristically drier are called rain shadow region. It's most common on the windward slopes of the mountain where the on-shore moisture laden-winds come from sea.
