Semiarid deserts experience similar conditions to hot deserts, however, the maximum and minimum temperatures tend to be less extreme, and generally range from 10 to 38 °C. Coastal deserts are cooler than hot and semiarid deserts, with average summer temperatures ranging between 13 and 24 °C. They also feature higher total rainfall values.
Nitrogen fixed by crusts has been shown to leak into surrounding substrate and can be taken up by plants, bacteria, and fungi. Nitrogen fixation has been recorded at rates of 0.7–100 kg/ha per year, from hot deserts in Australia to cold deserts. [11] Estimates of total biological nitrogen fixation are ~ 49 Tg/year (27–99 Tg/year). [10]
Cold desert climates (BWk) usually feature hot (or warm in a few instances), dry summers, though summers are not typically as hot as hot desert climates. Unlike hot desert climates, cold desert climates tend to feature cold, dry winters. Snow tends to be rare in regions with this climate. The Gobi Desert in northern China and Mongolia is one ...
A hot desert climate tends to have two seasons: a long, hot summer and a shorter, mild winter. Phoenix has four months (June-September) when the historical average high temperature is 100 degrees ...
The largest hot desert in the world, the Sahara, covers 9 million square kilometres (3.5 × 10 ^ 6 sq mi) and contains several ergs, such as the Chech Erg and the Issaouane Erg in Algeria. [5] Approximately 85% of all the Earth's mobile sand is found in ergs that are greater than 32,000 km 2 (12,355 sq mi), [6] the largest being the Rub' al ...
Despite its low surface atmospheric pressure (only 1/100 of that of Earth), the patterns of atmospheric circulation on Mars have formed a sea of circumpolar sand more than 5 million km 2 (1.9 million sq mi) in the area, larger than most deserts on Earth. The Martian deserts consist of half-moon dunes in flat areas near the permanent polar ice ...
The Sahara Desert in North Africa is the largest hot desert in the world and is one of the hottest, driest and sunniest places on Earth. Located just south of the Sahara is a narrow semi-desert steppe (a semi-arid region) called the Sahel , while Africa's most southern areas contain both savanna plains , and its central portion, including the ...
(CNN) — Striking images from the Sahara Desert show large lakes etched into rolling sand dunes after one of the most arid, barren places in the world was hit with its first floods in decades ...
