Areas with an arid (desert) climate (BW) usually receive less than 250 mm (10 in) of rain a year (see climate graph for Ciudad Juárez). This is the climate of the Sahara Desert and Central Australia. In Mexico dry desert areas include most of Baja California, western Sonora, and the...
题目The Sahara is the world's largest and most magic desert,but knowledge about it is surprisingly limited.Even estimates of when it formed vary widely,from more than five million years ago to mere thousands.Now,however,geographers studying wind-carried Saharan dust on the Ca...

You can explore the climate for any location like the Amazon rainforest, West-Africa savannas, Sahara desert, Siberian Tundra or the Himalaya. Hourly historical weather data since 1940 for Bér Tialane can be purchased with history+. Download variables such as temperature, wind, clouds and precip...
and in 10 years they would be in poverty, due to the fact that a decrease in average rainfall and an increase in the droughts have led to an estimated 90% of Egyptian agricultural lands being threatened by desertification. Consequently, he wanted to stop the Sahara Desert from desertification...
I think if we are going to discuss cooling sensibly, we might start asking whether places currently too dry and hot for agriculture might become fertile again? After all, you don’t find huge oil reserves under the Sahara desert if at one time the Sahara were not a jungle, do you?
High frequencies (>300 days/yr) of dry days are observed over most of the arid subtropical regions, such as the Sahara Desert, Afghanistan, part of northwest India, Pakistan, the Southwest USA, parts of Peru, Chile, South Africa, Australia and the polar regions. Models underestimate the ...
The global temperature graph from NASA[8]below shows a marked increase in the rate of change over recent years. This is likely the beginning of a “sharp rise in temperature over 50 years”, similar to that which occurred 11,400 years ago when Sedna was last this close to Earth. ...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
The Noor Ouarzazate Concentrated Solar Complex is being developed 10 kms north-east of the city of Ouarzazate at the edge of Sahara Desert about 190 kms from Marrakesh. Phase One of the project involves the construction of a 160MW concentrated solar power (CSP) plant named Noor I, while Phas...
