What is precipitation? Precipitation is any form of moisture which falls to the earth. This includes rain, snow, hail and sleet. Precipitation occurs when water. Frontal rainfall happens where warm fronts meet cold fronts. The British Isles are Convectional rainfall is common where the sun heats the land near the sea. Convection occurs when the Earth’s surface, especially within a Convective rain and light precipitation are the result of.

Frontal Rainfall Stage 1. What factors affect population density? Graupel accumulation in Elko, Nevada. Frontal precipitation is the result of frontal systems surrounding extratropical cyclones or lows, which form when warm and tropical air meets cooler air. These usually include thunder and lightening due to the electrical charge created by unstable conditions. Convection occurs when the Earth’s surface, especially within a conditionally unstable or moist atmospherebecomes heated more than its surroundings and in turn leading to significant evaporation.

The British Isles are affected by a number of different air masses. Convective and stratiform rainfall in the tropics. Stratiform precipitation occurs when large air masses rise diagonally as larger-scale atmospheric dynamics force them to move over each other. Weather Hazards What is the difference between a tornado and a hurricane? In South America, the Andes mountain range blocks Pacific Ocean moisture that arrives on the continent, resulting in a desert-like climate just downwind across western Argentina.

This page was last edited on 16 Decemberat rainffall They form in the Atlantic and move east across the country, bringing changeable weather. Convective precipitation occurs when air rises vertically through the temporarily self-sustaining mechanism of convection.

Stage 2 As the air rises it cools and water vapour condenses to form clouds. In meteorologythe various types of precipitation often include the character or phase rainfall the precipitation which is falling to ground level.

Frozen forms of precipitation include snowice needlessleethailand graupel. Rain or drizzle which freezes on contact within a subfreezing air mass gains the preceding adjective “freezing”, becoming known as freezing rain or freezing drizzle.

Cold fronts occur when a mass of cooler air dislodges a mass of warm air. British rainfall Depressions pass over Britain frequently. In the UK, depressions often follow a similar pattern.


Convectional rainfall When the land warms up, it heats the air above it.

Precipitation types

Frontal precipitation typically falls out of nimbostratus clouds. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation.

Orographic precipitation is similar, except the upwards motion is forced when a moving airmass encounters the rising slope of a landform such as a mountain ridge. The sun heats the ground and warm air rises. This includes rain, snow, hail and sleet. The Climate of the Earth. By continuing to browse the site, you are agreeing to our use of cookies.

Warm fronts are followed by extended periods of light arinfall and drizzle due to the fact that, after the warm air rises above the cooler air which remains on the groundit gradually cools due to the air’s expansion while being lifted, which forms clouds and leads to precipitation.
