How is Convectional precipitation formed?

How is Convectional precipitation formed?

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. As the clouds continue to grow the weight of the water droplets can eventually lead to precipitation.

What is another name for conventional rainfall?

Convective rain, or showery precipitation, occurs from convective clouds, e.g., cumulonimbus or cumulus congestus . It falls as showers with rapidly changing intensity.

Where does convection precipitation occur?

Convectional rainfall is widespread in areas where the ground is heated by the hot sun, such as the Tropics. This is why areas, such as the Amazon Rainforest, experience heavy rainfall most afternoons.

Where is Convectional rainfall experienced?

How is Convectional formed?

Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it. This causes the air to expand and rise. As the air rises, it cools and condenses.

What are the effects of conventional rainfall?

Conventional Rainfall The, air on being heated, becomes light and rises up in convection currents. As it rises, it expands and loses heat and consequently, condensation takes place and cumulous clouds are formed. This process releases latent heat of condensation which further heats the air and forces the air to go further up.

What causes convectional rainfall?

1. CONVECTIONAL RAINFALL Convectional rain is caused by convection where the surface layer of the atmosphere is heated causing the moisture laden air to rise. The condition of rising currents of warm air separated by more wide-spread areas of slowly sinking air is referred to as CONVECTION.

How convectional rainfall is caused?

The sun heats the ground; the air warms up and becomes very hot.

  • The hot air becomes light and rises upwards.
  • This process releases the latent heat of condensation,which further heats the air,and the air is forced to go up further.
  • When the cumulus cloud is saturated,it begins to precipitate with heavy and thundery showers.

    • How does convectional rainfall occur?

    Convectional rainfall occurs when the warm air deflected from a landform rises and forms rain clouds. Convectional rainfall is very common in tropical areas as well as areas in southeastern England.
