Originally based on the sources for the uplifting of the air, there are three main types of rainfall. 1. Convectional rainfall
2. Cyclonic/Frontal rainfall
3. Orographic/Relief rainfall
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
Necessary conditions for Convective rainfall
1. Intense heating of the surface which causes the air to expand and rise.
2. Abundant supply of moisture in the air to produce a very high relative humidity.

Turbulence in the atmosphere and surface obstructions such as hills and mountains provide the initial upward push for the air. This rainfall occurs throughout the year near the equator daily in the afternoon. In middle latitudes, convectional rainfall occurs in early summer, in continental interiors.
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.

In a zone of horizontal wind divergence, the warm air forced up over the colder air. In this slow ascend pressure decreases, air expands and cools, condensation and cooling produce a precipitation. These fronts and associated weather phenomenon are best developed in the middle latitudes, most of the winter precipitation of low lands in the middle latitudes is cyclonic or frontal is origin.
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 sideof 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.

Ideal condition for heavy orographic rainfall is a high relatively continuous mountain frontier (boundary) close to the coast and the winds from off a warm ocean meet the barrier at right angles. This is exactly the case with western Ghats in India, which lies athwart (perpendicular) the south-west monsoon.

Convectional rainfall occurs in singa pore

Monsoons with heavy rainfall are normal in the Singapore which mainly occurs through the convectional method of rainfall.
In this convectional method, the solar heat energy evaporates the water of the earth's surface which causes the massive amount of rainfall.
Singapore's monsoons are mostly occurred by this convectional method only.
