  Cloud cover above the earth

Image : Cloud cover over the Earth. This map shows a mean cover of all the observations of NASA satellites between July 2002 and April 2015. The colors range from dark blue (no clouds) to light blue (few clouds) and white (frequent clouds ). There are three "bands" where the skies of Earth are often cloudy. But in some places on Earth, the shape of the landscape favors the deserts, the desert of the Tibetan plateau to the north of the Himalayan mountains, Death Valley desert in south-eastern California to east of the Sierra Nevada and the Atacama desert in South America.
