Understanding Convectional Rainfall
When the Sun heats the Earth's surface, the ground heats the air above it. Convection makes the air rise and cool. When it cools to the dew point, clouds form and rain zi255.com usually occurs on flat land. This type of rainfall often causes summer showers and thunderstorms. Convectional rainfall When the land warms up, it heats the air above it. This causes the air to expand and rise. As the air rises it cools and condenses.
The causes of relief rainfall, frontal rainfall and conventional rainfall are examined. There are 3 main types of rainfall: relief, frontal and convectional. Home Geography Weather and climate There are 3 main types of rainfall: relief, frontal and convectional. There are 3 main types of rainfall: relief, frontal and convectional The causes of relief rainfall, frontal rainfall and conventional rainfall are examined. Relief rainfall Relief rainfall occurs when air has been blown over the sea and is then forced up over an area of high land.
This causes the air to cool and the moisture in the air condenses and rain falls. Frontal rainfall Frontal rainfall occurs when warm air is forced to rise over cold air. The moisture in the warm air condenses as it cools which causes clouds and rain. Convectional rainfall How often to replace anode rod mostly in tropics where it is hot. When air is hot is rises and cools and condenses forming rain.
If the air is hot enough, it rises very quickly and can cause thunderstorms. Weather and climate. Britain's climate. UK water supply.

Convectional rainfall Occurs mostly in tropics where it is hot. When air is hot is rises and cools and condenses forming rain. If the air is hot enough, it rises very quickly and can cause thunderstorms.
Rain is a kind of precipitation. Precipitation is any kind of water that falls from clouds in the sky, like rain, hail , sleet and snow. It is measured by a rain gauge. Rain is part of the water cycle. Clouds will often absorb smoke to create rain, commonly referred to as "nature's laundry" due to this process. Some places have frequent rain. This makes rainforest s.
Some have little rain. This makes desert s. A rainstorm is a sudden heavy fall of rain. It may cause flash floods in valleys. Heavy rain for a long time may make floods that destroy houses and drown people. Also, landslides may happen. When the Sun heats the Earth's surface, the ground heats the air above it.
Convection makes the air rise and cool. When it cools to the dew point , clouds form and rain follows. This usually occurs on flat land. This type of rainfall often causes summer showers and thunderstorms. Relief rain usually occurs along coastal areas where a line of hills runs along the coast.
When wet onshore wind from the sea meets a mountain , hill or any other sort of barrier , it is forced to rise along the slope and cools. When the air temperature falls to its dew point, water vapour condenses to form clouds. When the clouds can no longer hold the water droplets, relief rain begins to fall on the windward slope of the mountain. On the leeward slope , air sinks, it is warmed and further dried by compression. Therefore, the leeward slope is known as rain shadow.
Moist winds blow in from the sea and are forced to rise over the land. The air cools and the water vapour condenses, forming rain drops. The rainiest places in the world are places that have relief rainfall. Frontal rain happens when cooler air and warmer, humid air meet in a weather front.
The less dense warm air rises and condenses forming clouds. These clouds grow and eventually create rain. In some places on the northern temperate zone the cold air front tends to come from the north west and the warm air front comes from the south west. Some people collect rain in a rainwater tank. People use rainwater for watering plants, cleaning the house, bathing, or drinking. It is not always safe to drink rainwater. KidzSearch Safe Wikipedia for Kids. Jump to: navigation , search.
