Causes of sandstorms In desert areas, sandstorms are most commonly caused by either thunderstorm outflows(外流) or strong pressure gradients(气压梯度)which cause an increase in wind speed over a wide area. In some cases, dust and sand may set a limit to a shallow depth by a low-lying tem...
The spotted hyena is Africa's most successful predator—and one of its most misunderstood animals. But decades of cutting edge research is yielding greater understanding, respect, and protection.

And food itself needs to be more environmentally sound, employing fewer tricks that increase yields at the expense of the wider ecology. No more farming oases set up in bone-dry deserts; no more Salton Seas.This is difficult, but climate change may force us to do some of it regardless. ...
Precipitation may be an important driver of microbial colonization in volcanic terrains as microorganisms are deposited from the falling raindrops or snow (Fig. 5e)200. For dry deposition, major aeolian dust events in the Sahara201, Gobi202, and potentially polar deserts203 may allow certain ...
These natural particulates are produced in billions of tons annually, with particles from deserts alone estimated as upwards of 500 million tons per year to several billion [236], and from the view point of risk, the number of deaths attributed to respiratory exposure to these natural ...
