The Sahara (/ s ə ˈ h ɑːr ə /, / s ə ˈ h ær ə /) is a desert spanning across North Africa.With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999 The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross
Atmospheric rivers have a central role in the global water cycle. On any given day, atmospheric rivers account for over 90% of the global meridional (north-south) water vapor transport, yet they cover less than 10% of any given extratropical line of latitude. [4] Atmospheric rivers are also known to contribute to about 22% of total global ...
Several waterspouts were spotted near Destin, Florida this summer, but luckily none reached land, which is when they are most dangerous. Related: America's Most Dangerous Beaches Wikimedia Commons
Atmospheric rivers are long and relatively narrow bands of water vapor that form over an ocean and flow through the sky, transporting much of the moisture from the tropics to northern latitudes.
Atmospheric rivers could become stronger and have more impacts along the West Coast due to climate change. A new study shows how water rise and increased rainfall could impact residents who face ...
The Atacama Desert (Spanish: Desierto de Atacama) is a desert plateau located on the Pacific coast of South America, in the north of Chile.Stretching over a 1,600-kilometre-long (1,000-mile) strip of land west of the Andes Mountains, it covers an area of 105,000 km 2 (41,000 sq mi), [2] which increases to 128,000 km 2 (49,000 sq mi) if the barren lower slopes of the Andes are included.
A more specific version of an atmospheric river is a setup sometimes referred to as a "pineapple express." In this case, a plume of tropical moisture extends from near Hawaii to California or ...
