What causes a desert climate?

What are the causes of deserts?

The nine causes are: (1) Natural Situation (2) Air Circulation Pattern (3) Currents: A Hot Water Heating System (4) Oceanic Currents (5) Remote Situation From an Oceanic Moisture (6) Mountain Barrier (7) Rainless (8) Temperature and (9) Man in Desert Making. The world has always had its deserts.

What are the causes of desert and arid climates?

All these climatic, desert-producing factors – descending, drying air currents; mountain-produced rainshadows; distance from oceanic moisture sources; and cold ocean currents – are instrumental, sometimes singly, more often in combination, as primary forces producing arid lands.

Why do deserts form where they?

They are caused by cold ocean currents, which run along the coast. They cool the air and make it harder for the air to hold moisture. Most moisture falls as rain before it reaches the land, eg the Namib Desert in Africa. … Some deserts form in areas that lie at great distances from the sea.

Thus, these winds blow from east to west. … Thus, Thar is a desert.

How does climate influence the distribution of deserts?

The air travels in the upper atmosphere and sinks at approximately 30° north and 30° south of the Equator. When the air sinks it creates an area of high pressure. These high-pressure areas experience very dry and warm conditions resulting in a hot desert climate (eg the Sahara and Kalahari deserts).

What is hot climate?
