The Sahara has one of the harshest climates in the world. The prevailing north-easterly wind often causes sand storms and dust devils. When the wind blows towards the Mediterranean, it is known as sirocco and often reaches hurricane speeds in North Africa and southern Europe. Half of the Sahara receives less than 20 mm of rain per year, and the rest receives up to 100 mm per year. The rainfall happens very rarely, but when it does it is usually torrential when it occurs after long dry periods.
