David's Stream
The David's Current is a seasonal, warm ocean current in the northern Pacific Ocean on the west coast of the United States . It brings mild water temperatures and humidity to Southern California's coastal waters during the winter months.
In winter, the influence of the trade winds on the North American Pacific coast decreases and the west drift shifts towards the equator. The onshore winds approaching from the south-west drive the Current of David. As a drift current , this ocean current only moves less than 1 knot . But its climatic influence is all the greater, because its warm surface water is pushed as a wedge between the California coast and the cold California Current . As a countercurrent, it brings mild water temperatures of around 16 ° C to the coasts off San Francisco and Monterey from October to February . During these months, the " upwelling " of cold upwelling water is interrupted, which is noticeable on the coast through increased rainfall. In March the Davidson Current decreases again and the California Current gains influence again.
