Why is Africa the driest continent?
The continent is established as the driest continent despite other larger continents such as Africa having larger areas of deserts. The continent also has incredibly high evaporation rate with over 75% of the land mass experiencing a potential evaporation rate that is higher than 98.4 inches per year.
Is Africa mostly dry?
Northern Africa is one of the driest regions on Earth, home to the Sahara desert, the largest hot desert in the world. This extremely dry region, where it’s not uncommon to have no rain for over a year in some places was once a tropical humid area.
Why is Sahara so dry?
The climate of the Sahara has undergone enormous variations between wet and dry over the last few hundred thousand years, believed to be caused by long-term changes in the North African climate cycle that alters the path of the North African Monsoon – usually southward.
Where is driest place on earth?
The driest place on earth officially is in the Atacama Desert in Northern Chile and southern Peru, in western South America (Figure SM4. 3).
What country has no rain?

Which country rain never fall?

Why is northern Africa one of the driest?
The cooler temperatures in the north weakened the high altitude Tropical Easterly Jet, which consistently brought moisture into northern Africa. Due to the weakening of the Tropical Easterly Jet, the African Easterly Jet strengthened, which indirectly inhibits rainfall in northern Africa.
Which is the best description of the climate of Africa?
Climate of Africa. Precipitation intensity is always high, and it is a hot continent. Warm and hot climates prevail all over Africa, but the northern part is that most marked by aridity and high temperatures. Only the northernmost and the southernmost fringes of the continent have a Mediterranean climate.
What are the dry and rainy seasons in Africa?
Dry and Rainy Seasons: Horn of Africa. Weather in the Horn of Africa (including Somalia, Ethiopia, Eritrea and Djibouti) is characterized by the region’s mountainous geography and cannot be easily defined.
Why is Africa the most tropical continent in the world?
The equator runs through the middle of Africa, as do the Tropic of Cancer and the Tropic of Capricorn, making Africa the most tropical continent. The already hot and dry climate that straddles the equator, makes it the most vulnerable continent to climate change .
