Cloud Vortex Near Adelaide, Australia

34.9S 138.5E

Australia – March 21st, 2013

A 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.

Cloud Vortex and Culgoa River, Australia

Australia – February 19th, 2013

A cloud vortex spins over the ocean east of the coast of Queensland, Australia. Inland, parts of the Darling Riverine Plains can be viewed, with rivers cutting across the dry landscape.

Visible near the center of the left half of the image, near a large green patch, is the Culgoa River. It is a watercourse that is part of the Darling catchment within the Murray–Darling basin, is located in the south west district of Queensland and the Orana district of New South Wales, Australia.

The river is a continuation of the western branch of the Balonne River in southern Queensland, near Dirranbandi, and flows generally south-west across parts of the Darling Riverine Plains, joined by ten tributaries, including the Balonne and Birrie rivers, before forming its confluence with the Darling River near Bourke; descending 78 metres (256 ft) over the course of its 489 kilometres (304 mi) length.

Cubbie Station, located on the Culgoa River, is situated adjacent to a large diversion channel which permits a large farm, under licence to store 460,000 megalitres (16,000×106 cu ft) of river water. According to downstream farmers in 2008, large cotton farms, such as Cubbie Station, have reduced the traditional flow of the Culgoa River by one third. By 2009, downstream farmers where claiming that due to upstream water entitlements on the Culgoa River, since 2000, the Lower Balonne floodplain had not received enough water to flood the plains. Prior to the granting of these rights, the Lower Balonne River flooded every two or three years; impacting the sustainability of flora, fauna, birdlife, and economic returns from grazing livestock and cropping.

Cloud Vortex Southeast of Greenland

Greenland – January 26th, 2013

A large area of convection forming a spiral cloud vortex (bottom right quadrant) can be seen southeast of the southern tip of Greenland (upper left quadrant). It is a visible example of a convection current, the transfer of heat energy by the movement or flow of a substance from one position to another.

Vortex Near Balearic Islands, Spain

Spain - August 13th, 2011

Visible off the eastern coast of Spain and northern coast of Algeria, over the Mediterranean Sea, is a cloud vortex.

Spain’s Balearic Islands can be observed to the northeast of the vortex, near the upper right edge (from northeast to southwest) Majorca, Minorca, Ibiza and Formentera.

Cloud Vortex Off Coast of Namib Desert, Namibia

Namibia - November 30th, 2010

The spiralled shape of a cloud vortex is visible off the coast of Namibia, by the Namib Desert. Heavy fog and clouds are often present off the coast in this area, known as the Skeleton Coast due to the shipwrecks caused over the years by poor visibility from the dense fog.

The desert itself appears bright orange in color, gradually darkening as one moves inland. The tan area north of the orange is part of the desert, although it is composed mostly of bedrock rather than sand.
