Snow on the Dunes of the Taklamakan Desert, China39.7N 85.1E
These images show snow on and edges of the Taklamakan desert (full image) and some of its dunes,(close-up), in China.
Although it may seem counterintuitive, given our idea of deserts as hot, sun-battered places, they can be very cold places where snow sometimes does fall. The definition of a desert is how little precipitation the area gets. It has no bearing on how hot or cold it is.
Deserts are typically defined as areas that receive an average annual precipitation of less than 250 mm (10 in), or as areas in which more water is lost due to evaporation than falls as precipitation.
