What's the climate like on the west coast of the mainland near the Tropic of Cancer?

The west coast of the mainland near the Tropic of Cancer has a tropical desert climate. The formation, characteristics and vegetation types of tropical desert climate are analyzed.

The causes of tropical desert climate;

1. In areas controlled by the subtropical high belt all the year round (areas where the trade winds have little or no influence), the airflow sinks and there is little rain, forming a tropical desert climate.

2. In the control area of trade winds (northeast trade winds or southeast trade winds) (areas not affected by subtropical high), the wind blows from high latitude to low latitude, and the temperature rises, which makes it difficult to form clouds and cause rainfall, thus forming a tropical desert climate.

3. The area controlled alternately by the two is also a region with little rain, and of course it is a tropical desert climate.

Climatic characteristics of tropical desert;

1, dry and hot all year round. It is distributed outside the tropical dry and wet season climate zone, roughly between north latitude 15 ~ 30, and is most widely distributed in North Africa, Southwest Asia and central and western Australia. The tropical arid climate zone is controlled by subtropical high and trade winds all the year round, and the tropical continental air mass prevails, and the airflow sinks, and the hot and dry weather becomes the main feature of this climate.

2, the temperature is high, and it is known as the "hot pole" in the world. There is little precipitation, the annual rainfall is less than 200 mm, and it changes greatly, even it doesn't rain for many years. Strong sunshine and strong evaporation make the climate drier. Tropical semi-arid climate, distributed in the outer edge of tropical arid climate zone, mainly has the following characteristics: first, the rainy season is short, and the annual precipitation can be increased to 500mm；; Second, the temperature on the high latitude side is not as high as that on the low latitude side.

Vegetation types of tropical desert climate:

1. The vegetation type of tropical desert climate is tropical desert. Evergreen broad-leaved forest is a vegetation type with Mediterranean climate.
