So basically Rainfall is mainly divided into three types:

1.Convectional rainfall

2.Orographic or relief rainfall

3.Cyclonic or frontal rainfall

Characteristics of Convectional Rainfall:

The air heats & the lighter air rises up in convection currents,now as the air rises it expands and temperature drops and clouds fall due to condensation, rains are accompanied with heavy shower and thunder & lightning that dont last long.

Characteristics of Ornographic rainfall:

When the saturated air mass comes across a mountain, it is forced to rise.The rising air expands, eventually, the temperature falls, and the moisture gets condensed.

Characteristics of Cyclonic rainfall:

Cyclonic activity causes cyclonic rain and it occurs along the fronts of the cyclone. When two masses of air of unlike density, temperature, and humidity meet then it is formed.

Types of Rainfall based on Intensity

The types of rainfall based on intensity can be classified as:

1. Light rain – Rate of rain varies between 0 to 2.5 millimetres
2. Moderate rain – Rate of rain varies between 2.6 millimetres to 7.6 millimetres
3. Heavy rain – Rate of rain is beyond 7.6 millimetres

Based on the sources for the uplifting of the air,  three main types of rainfall exists.

1. Convectional rainfall.

2. Cyclonic/Frontal rainfall.

3. Orographic/Relief rainfall.
