As the air rises, it cools, and water vapour condenses to form clouds. Convectional rainfall is widespread in areas where the ground is heated by the hot sun, such as the Tropics. Equatorward-moving air behind a cold front occurs in pools of dense high pressure known as polar highs and arctic highs. It is prevalent in Britain and Ireland, which is associated with the movement of depressions over the country. The air cools as it rises and Air that rose just north of the equator flows north. Stage 1. The position of the polar front slopes upward toward colder air. The convergence region for lower-level northeast and southeast trade winds is called the intertropical convergence zone (ITCZ). Convectional rainfall occurs when the energy of the sun (or insolation) heats the earths surface and causes water to evaporate changing to water vapor. Geoscience Australia hosts earth science related programs and events for teachers. Limestone Case Study Malham, The Yorkshire Dales. What is the value of the tropical rainforest? Geoscience Australia Where are Temperate Deciduous Woodlands Located? Convectional rainfall occurs most frequently in regions that are extremely hot, either during the day, as in the tropics, or during the summer, as in temperate areas.
