Question

how do convection current in the atmosphere help in Rainfall

Answer 1

Convection is one of the major processes creating our weather. Convection is one cause of rising air in our atmosphere, usually warm air rises above cold air.

Answer 2

Convectional rainfall occurs when the energy of the sun (or insolation) heats the earth’s surface and causes water to evaporate changing to water vapor. This warm, moist air then rises and as it rises it cools. The air reaches a point called the condensation level where it has cooled to such an extent that the water vapor condenses and turns back to a liquid form. This process of condensation high in the atmosphere leads to the development of clouds. As the clouds continue to grow the weight of the water droplets can eventually lead to precipitation.
