Cloud Vortex Near Adelaide, Australia
34.9S 138.5EA large cloud vortex swirls off the coast of South Australia, near Adelaide. Visible north of the vortex center are the Gulf of Spencer (larger, west) and the Gulf of St. Vincent (smaller, east). Such vortices can form for a variety of reasons, including upper air circulation effects, mechanical effects induced by nearby mountains, surface heating from the ocean, and association with a cold front.
