The Cape Doctor, a persistent dry southeasterly blows across Cape Town, South Africa, clearing away pollution and bringing in fresh clean sea air.
This wind is important to marine and plant life. It aerates the lagoon and river mouth, forcing life-giving oxygen into the shallow water.
It also helps the fynbos that grow in the thin soil of Table Mountain by causing condensation that brings them much-needed moisture. When a cloud forms over the mountain, this welcome "table cloth" brings rain to the eastern slopes.
