Mars may be dead in the biological sense, but it is nonetheless a dynamic and fascinating world. Telescopic observers have long followed the variations in the dark areas and the polar caps, and recorded the changing white clouds and the more mysterious yellow clouds, which sometimes conceal the outlines of the dark markings for months on end. This is a review of these yellow clouds, which we now know to be dust storms. It describes their location, development, composition and seasonal occurrence, their influence on the climate of the Red Planet, and demonstrates that they are the sole cause of long-term changes in the dark markings. Members of the Association have contributed significantly to our developing understanding of these phenomena, and it is to be expected that future BAA observations will be important to help resolve ongoing questions.
