why is the tropical desert climate dry over the course of the entire year

by Germaine Larkin 4 min read

The tropical desert is an environment of extremes: it is the driest and hottest place on earth. Rainfall is sporadic and in some years no measurable precipitation falls at all. The terribly dry conditions of the deserts is due to the year-round influence of subtropical high pressure and continentality.

Why are the deserts in Africa so dry?

The reason for the dryness of these deserts is the influence of subtropical high pressure and continentality. The main trees and bushes found in these areas are acacia, cactus, Babul, etc. Wildlife species are also found here. Mules, gazelles, camels, snakes, and lizards are the wildlife species found in this region.

As you would expect, temperatures at the equator are highest. Warm air rises containing evaporated moisture.

Where is a tropical wet and dry climate typically observed?

Tropical wet and dry climate is typically observed within the tropics. The tropics are two lines of latitude at 23.5° north and 23.5° south of the Equator. Land within this area obtains direct sunlight throughout most of the year.

Why deserts remain dry throughout the year?

Physical geography. A desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain, but it may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area.

Why is the desert climate hot and dry?

Explanation: In Desert temperature is high during most parts of the year and the desert receives very less rainfall hence the climate in the desert will be hot and dry.

Why are deserts hot and dry GCSE?

This is due to the lack of rainfall. As it is so hot water is drawn up to the surface of the soil by evaporation . As the water evaporates, salts are left behind on the surface of the soil.

What is dry climate?

Dry Climates Regions lying within the dry climate group occur where precipitation is low. There are two dry climate types: arid and semiarid. Most arid climates receive 10 to 30 centimeters (four to 12 inches) of rain each year, and semiarid climates receive enough to support extensive grasslands.

What is the tropical climate?

What is Tropical Climate? The tropical wet and dry climate in geology is also called the tropical savanna and is part of the Köppen climate division system that groups climates based on vegetation. Having signs of the monsoon climate, the tropical climate is represented by a wet season and a dry season.

Why is the savanna not verdant?

Answer: Due to the inconsistent rainfall, vegetation on the tropical savanna is not verdant like it is in the monsoon or the rainforest climate. Rather, tall grasses domineer over the land, with infrequent areas of drought-resistant trees and shrubs. Plantlife can contain waxy leaves and thorns, which enable it to survive the dry climate.

How hot is the weather in the wet season?

Answer: In the wet season, temperatures average about 77°F. While, during the dry season, temperatures average about 68°F. The temperature remains high throughout the year due to the latitude where this climate is seen. Areas near the equator obtain consistent direct sunlight and thus, heat. A little difference in temperature is sufficient to change the wind patterns and keep this area dry for most of the year until the winds shift and the rainy season starts.

What is the difference between wet and dry seasons?

1. Wet season (summer) 2. Dry season (winter) Generally, the dry season lasts longer. During the dry season, plant life and animal life struggle to tackle the dry conditions, but as the rainy season starts, plants turn green, ponds fill up, and animal life blossoms.

What animals live in tropical climates?

Answer: Larger animals found in the tropical climate are most commonly migratory and travel in herds, such as the zebras, giraffes, gazelles and wildebeest in Africa. These larger herbivores that manage to survive on the grass of the savanna get along with them, such as lions in Africa and tigers in India.
