Hey friend,
Here is your answer:
There are three different types of rainfall:
• Relief rainfall : It occurs when a mountain or plateau comes in the path of the moisture laden winds. The side of the mountain facing towards the wind is called the windward side. The moist, warm air rises along the windward side. As the air descends, the temperature falls. When the temperature falls below dew point, there is condensation and rainfall. As the air descends down the other side of the mountain, the leeward side becomes warmer and drier. Relief rainfall is also known as orographic rainfall.
• Conventional rainfall : It occurs throughout the year in the equatorial belt. During the day, the vertical rays of the sun heat up the land surface. The air near the surface also gets heated and rises up. The cooler air from above sinks, only to be heated and forced to rise again. Thus, a convectional air current is set up. As the hot air rises, it cools down. Clouds from when the temperature of the air falls below dew point. These clouds lead to heavy rainfall towards the afternoon or evening. This rainfall is accompanied with thunder and lightning.
• Frontal/Cyclonic rainfall : Within a cyclone warm air and cold air from opposite directions often meet. When they meet, a zone of separation called font is formed. Warm air which is lighter rises obliquely over cold air. As the warm air rises, it cools, condenses and causes rainfall.
Hope it helps u.

three types of rainfall are:-
Relief Rainfall
Relief rainfall occurs very frequently near mountains beside the sea.
Moisture-laden wind blows in from the sea. Because the wind meets a high mountain, it is forced to rise upwards. As it rises upwards, it is cooled and cloud is formed.
The cloud becomes saturated with water vapour and it begins to precipitate on the side of the mountain facing the sea. This side of the mountain is known as the windward side.
The cloud precipitates the most on the windward side of the mountain. By the time the cloud meets the other side, which is called the leeward side, the cloud has already lost most of its moisture so it rains very little there.
Convectional Rainfall
You may be outside on a picnic on a hot summers day. You are enjoying yourself and you are soaking in the rays of sunshine. Suddenly, the sky gets darker and a dark, grey cumulus cloud is coming your way. Without warning, the heavens open and it begins to rain, with an almost thundery feel. Convectional rain occurs frequently on hot days usually giving cumulus cloud and thundery showers.
The sun heats the Earth's ground. This causes the air to warm and become very hot.
The air rises upwards. The air is then cooled and condenses to form cumulus cloud.
Frontal Rainfall
This occurs when a warm, tropical air mass comes in contact with a cold, polar air mass and is very common in Britain and Ireland.
A warm, tropical air mass comes in contact with a cold, polar air mass. Because the air in the warm front is well, warm then it rises over the cold front.
The air is cooled and condenses to form stratus cloud.
When the stratus cloud becomes saturated, it begins to precipitate.
