Orange River and Cape of Good Hope, South Africa

34.3S 18.4E

March 9th, 2012 Category: Rivers

Namibia - March 5th, 2012

The Orange River can be seen crossing the upper part of this image of South Africa, more or less parallel to the top edge. Despite its name, the river is most visible in the upper right quadrant as a thick green line.

The river forms part of the international borders between South Africa and Namibia and between South Africa and Lesotho, as well as several provincial borders within South Africa. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. In the full image, a small amount of sediments can be seen entering the Atlantic by the rivermouth. 

Visible in the lower part of the image are Cape Town and the Cape of Good Hope, in the Western Cape region of South Africa.  The Western Cape is exceptionally topographically diverse. Most of the province falls within the Cape Fold Belt, a range of sandstone folded mountains. The far interior forms part of the Karoo Basin and is generally arid and hilly with a sharp escarpment in the north. Coastal areas range from sandy between capes, to rocky to steep and mountainous in places.

Track of TS 14S

Tropical Cyclone Irina (14S), is located approximately 415 nm east-southeast of Maputo, Mozambique. The system has tracked west-northwestward at 04 knots over the past six hours.

The intensity is estimated at 40 knots. Maximum significant wave height is 14 feet. TC 14S continues to track generally westward along the periphery of a low-level subtropical steering ridge to the south. This motion is expected to continue through the forecast period.

Animated infrared satellite imagery shows convection becoming shallower over a still tightly-wrapped low-level circulation center. Upper level outflow has decreased significantly over the past 12 hours. Mminimal outflow and passage over a cool sea surface will lead to dissipation of the system by TAU 24.

Mountainous Terrain of Landlocked Lesotho – January 12th, 2012

Lesotho and South Africa - January 11th, 2012

The mountainous area in the upper left quadrant of this orthorectified wide-swath ASAR image is part of Lesotho, a landlocked country and enclave, completely surrounded by its only neighboring country, South Africa. Lesotho covers 30,355 km2 (11,720 sq mi).

It is the only independent state in the world that lies entirely above 1,000 metres (3,281 ft) in elevation. Its lowest point of 1,400 metres (4,593 ft) is thus the highest in the world. Over 80% of the country lies above 1,800 metres (5,906 ft). Lesotho is also the southernmost landlocked country in the world.

Vegetation Index of Coastal Mozambique and South Africa

Mozambique and South Africa - November 8th, 2011

This FAPAR image stretches from southern Mozambique (above) to northeastern South Africa (below). The vegetation index throughout the image ranges mostly from low (yellow) to good (green), with a few areas of high (rusty red) activity.

Photosynthetic activity appears higher near the coast, a low-lying area, then becomes lower as one moves westward and up the mountainous escarpment, known as the Great Escarpment, that separates the coast from the high inland plateau.

Great Escarpment and Coastal Zone of South Africa and Mozambique

Mozambique and South Africa - November 8th, 2011

The full version of this image stretches from Mozambique to South Africa, although only the latter is visible in the thumbnail. In the full image, popcorn clouds can be seen over the Mozambican terrain.

South Africa occupies the southern tip of Africa, its coastline stretching more than 2,500 km (1,553 mi) from the desert border with Namibia on the Atlantic (western) coast southwards around the tip of Africa and then north to the border with Mozambique on the Indian Ocean.

The low-lying coastal zone is narrow for much of that distance, soon giving way to a mountainous escarpment (Great Escarpment) that separates the coast from the high inland plateau. Here, the coastal areas appear more green and vegetated than the escarpment.
