The Wrath of the Sand Storm The dust clouds we suffer from time to time during the hot summer months are annoying, and leave us with a slightly dirtier world to clean up after. But these are but the sons and daughters of the much larger and more aggressive sand storms, which can create clouds of dust several kilometer in height and can bury everything underneath them in up to 30 cm of sand. The phenomenon is more common in North Africa and Australia, as well Saudi Arabia, Iraq and the South West US. Usually, the cause is the meeting of two different climates that cause a big storm which moves clouds of dust and sand in enormous quantities and in enormous speeds.� |
