Why does it rain a lot in the tropics?

Why does it rain a lot in the tropics?

As the sun shines strongly on the tropics — particularly on the warm oceans which have an effectively infinite amount of water to evaporate into the air — the overlying atmosphere becomes very humid. If enough water condenses, the cloud droplets can become large enough to fall as rain.

What is there so much rain in tropical regions?

The reason the rain belt is situated near the tropics can be attributed to the fact that the sun’s radiation is strongest near the equator, which is located in the middle of the tropics. This solar radiation generates large amounts of heat near the equator. This causes the air at ground level in the tropics to warm up.

Why does the desert get little rain?

Hot, moist air rises into the atmosphere near the Equator. As the air rises, it cools and drops its moisture as heavy tropical rains. The descending air hinders the formation of clouds, so very little rain falls on the land below. The world’s largest hot desert, the Sahara, is a subtropical desert in northern Africa.

What is tropical rainfall?

Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as lowland equatorial evergreen rainforest.

What is the role of rainfall in the desert?

Explanation: Most deserts get what little precipitation they do receive in a few, heavy rainfalls, rather than many light rains spread out over the course of the year. This leads to seasonal lakes and rivers which may last a few months, or even only a few days.

Why is there so much rainfall at the equator?

Near the Earth’s equator, solar heating is intense year round. The Sun heats the ocean, evaporating tremendous amounts of water. The sun-warmed ocean heats the overlying air, which rises like a hot air balloon. As air rises, it cools, and water vapor condenses into rain.

When did tropical rain come out?

Tropical Rain was actually introduced all the way back in 2016 and is one of the first collaborations for G Fuel being inspired by the gamer FaZe Rain.

What causes rain in the desert?

Subtropical deserts are caused by the circulation patterns of air masses. Hot, moist air rises into the atmosphere near the Equator. As the air rises, it cools and drops its moisture as heavy tropical rains.

Why does the desert have less rainfall?

Some deserts are near the equator where the air is very dry. Some deserts are in the middle of a continent. By the time the wind gets there, it has little moisture. If rain falls it stays dry in deserts because the sand absorbs the water.

Why does it rain less in desert?

As the air rises, it cools and drops its moisture as heavy tropical rains. The resulting cooler, drier air mass moves away from the Equator. As it approaches the tropics, the air descends and warms up again. The descending air hinders the formation of clouds, so very little rain falls on the land below.

Why is the rainfall more only in the eastern coast of Australia?

The coast is influenced by the warm waters of the Tasman Sea, which moderate the temperature and provide moisture for abundant rain. The Great Dividing Range enhances rainfall near the coast, but contributes to a progressive decline in rainfall from east to west across the state.

Why is there more rain in the tropics?

A new study based in part on NASA satellite data has shown that an increase in large, well-organized thunderstorms is behind increased rainfall in the wettest regions of the tropics. Many scientists have long thought that in a warming world some regions are likely to see more rain because a warmer atmosphere is capable of holding more water vapor.

What is the average temperature in a tropical climate?

Tropical climates are characterized by monthly average temperatures of 18 ℃ (64.4 ℉) or higher year-round and feature hot temperatures. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm to varying degrees.

What’s the average precipitation in a tropical rainforest?

Tropical rainforest climate. All 12 months have average precipitation of at least 60 mm (2.4 in). These climates usually occur within 10° latitude of the equator.

Which is a characteristic feature of tropical regions?

The second distinctive climate feature of tropical regions is the dry season. As you can see from the diagram to the right of the Hadley circulation air rises above the ITCZ to create a low pressure zone, characterised by high humidity and rainfall.
