The driest place on Earth is in Antarctica in an area called the Dry Valleys, which have seen no rain for nearly 2 million years. The reason why this region receives no rain is due to Katabatic winds, winds from the mountains that are so heavy with moisture that gravity pulls them down and away from the Valleys..
Considering this, is Antartica dry?
Antarctica's climate is also very windy and dry. This may at first seem surprising with 99% of its area being covered by ice; and Antarctica certainly doesn't conform to the image that most people have of a desert. Yet, most of Antarctica is classed as a desert on the basis of its mean annual precipitation.
Also, what is the driest place on earth and what makes it so dry? First, this desert is located in the "rain shadow" between two mountain ranges, the Andes and the Chilean Coast Range. Second, winds called the Pacific Anticyclone flow through this area.
Hereof, why is Antarctica so cold dry and windy?
In addition the permanent ice cap reflects a large amount of sunlight. Also Antarctica is on average the highest continent and so temperature decreases with altitude. Due to the high average elevation in Antarctica there is also less atmospheric pressure, lower air pressures that contribute to keeping the region cold.
Is the Antarctica the driest place on Earth?
Dry Valleys, Antarctica Though Antarctica summons a mental picture of snow-covered terrain, it's Dry Valleys are actually the world's driest spot. The valleys have extremely low humidity and almost no ice or snow cover the largest ice-free region on the continent.
