Water vapour
The factors are moist air and rainfall.
The monsoon winds are responsible for the rainfall experienced over a greater part of India.
The main types of rainfall are convective, frontal, orographic, and cyclonic. Convective rainfall occurs when warm air rises and cools, leading to condensation and precipitation. Frontal rainfall happens when two air masses with different temperatures meet, causing the warm air to rise and cool. Orographic rainfall occurs when moist air is forced to rise over a mountain range, cooling and creating precipitation. Cyclonic rainfall results from the convergence of air masses around a low-pressure system, leading to widespread precipitation.
Orographic rainfall occurs when moist air is forced upwards by a barrier, such as a mountain range, leading to the air cooling and condensing to form clouds and precipitation. As the air rises over the barrier, it cools and releases moisture, resulting in increased rainfall on the windward side of the mountain range.
Another name for Relief rainfall is Orographic rainfall. This type of rainfall is caused by the lifting of moist air over a mountain range, resulting in cooling and condensation of the air, leading to precipitation.
Convectional rainfall occurs when warm air rises, cools, and condenses to form rain clouds. Relief rainfall occurs when moist air is forced to rise over elevated terrain and cool, leading to precipitation. Frontal rainfall occurs when two air masses with different temperatures and moisture content meet, causing the warmer air to rise and condense, resulting in rainfall.
Rainfall is caused by water vapor in the atmosphere condensing into liquid droplets or ice crystals, which then fall to the ground due to gravity. This process is often triggered by cooling of the air, such as through the uplift of air masses or the presence of a cold front.
Frontal rainfall occurs when warm and cold air masses meet, leading to the warm air rising and cooling, causing condensation and precipitation. Orographic rainfall happens when moist air is forced to rise over a barrier, such as a mountain range, leading to cooling, condensation, and rainfall on the windward side of the barrier.
Convectional rainfall is when the sun heats the ground and hot air rises, the hot air then cools down and forms clouds then it rains
Frontal rainfall is caused by the meeting of a warm air mass with a cold one. As the warm air rises and cools, it condenses to form clouds and precipitation. This type of rainfall is common in regions with distinct seasons and frontal systems.
There are three main types of rainfall, convectional rainfall, relief rainfall and frontal rainfall. Relief rainfall is when the warm moist air from the sea (Atlantic Ocean) is forced to rise over mountains and as the moist air gets higher it gets colder so it gradually condenses and becomes water droplets and it rains/ prcipitates. Relief rainfall is common along the west side of Britain where there are more high lands. Convestional rainfall is when the sun comes out and heats up the land, this causes the air around it to become warm too. The warm air currents rise and as it rises it gets colder so it gradually condenses and the water vapou become water droplets and it rains/precipitates. Convectional rainfall is mostly common around towards the south of Britain in the summer. Frontal rainfall is when cold air and warm air meet, the warm, light air wants to get past the heavy cold air so it casually rises above it. Its rising makes it get colder which makes the warm air cold air, it condenses and guess what? It rains/ precipitates! Frontal rainfall is mostly common all over Britain especially in the winter.
The barometer is used to measure air pressure while the rain gauge is used to measure the amount of rainfall.
