Dry climate tropical and hot temperature, definition | Where is a dry climate in the world

A characteristic feature of a dry tropical climate is the lack of changes in monsoons. As a result, all regions with such a climate are exposed to tropical air. The wind mode is very unstable, since many regions can be provided under the influence of anticyclones and blurry depression.


A dry tropical climate is characteristic of the desert areas of Africa, the Arabian Peninsula, Iran, Iraq and Central Australia. In their territories there are such species of deserts as: sugar and nasib in Africa; Non-foot and rub-al-Khali on the territory of the Arabian Peninsula; Big sand desert, Simpson, Gibson desert and a large Victoria desert in Australia; Sonoro and Nizhnekalifornia desert in California.

Climate factors

Air temperature

Regions with a dry tropical climate are characterized by higher air temperatures than in areas with a wet tropical climate. But most often the average maximum temperatures are at the same level. The highest temperature that was recorded on the ground is about 57.7 degrees Celsius. It was noted in Asia and North Africa. But most often the temperatures in the range of up to 57 degrees Celsius are very shortterm and lasts no more than one hour. Average daily fluctuations sometimes reach 40 degrees Celsius.

The hottest season is summer when the average temperature is not below +26 degrees Celsius. In winter, temperature fluctuate in the range from +22 degrees Celsius. The lowest temperature is +10 degrees Celsius.

Air humidity

Precipitation in territories with a dry tropical climate is extremely rare, but there are strong rains. Humidity depends on temperature. The higher the temperature the lower the humidity. The climate of the desert regions is characterized by a humidity of not more than 30% per year. Due to the very low moisture content in the air, even with serious temperature fluctuations, the moisture does not condensate. Due to strong overheating of air for deserts, sand storms are characteristic. At this moment, the sand turns into black clouds, eclipsing the sun, and spreads the wind into a long distance, destroying everything in its path. Another characteristic feature is mirages that are created by sunlight. As a result, the light refracts and creates interesting paintings on the horizon.


Soils of deserts located in a moderate belt are very scarce. They do not have turf, have low humus and high carbonism.  In total, four types of deserts are distinguished, which differ in their soil: sandy, rocky, salt and clay and clay.

Sand soils are very diverse. In some territories, shrubs can grow, and the rest will be devoid of any vegetation. It is extremely difficult to move in a sandy desert.

Rocky deserts are very rough and solid soil. They are the most common and occupy about 70% of all sugar. There you can find various unpretentious succulents and lichens.

Salonchak. The difference between this species is the predominance of a large concentration of salts in the soil. As a rule, deserts are covered with a solid crust of salt and can absorb a large animal or humans.

Clay. The soil consists of a large clay layer with a smooth texture. They differ in slight mobility and absorb any moisture well, preventing it from penetrating deep.

Nature in territories with a dry tropical climate

In the deserts, natural conditions are characterized by the extremely small spread of any vegetation. In tropical deserts, plants got rid of the water with long roots. Most often they have small leaves, which are covered with wax or fluff. Many species of plants spreading in territories with a dry tropical climate do not have leaves at all.

Animals adapted to existence in the natural conditions of deserts. Most of them are active in the dark, and during the day they hide from the heat in their holes.
