Webocean current, stream made up of horizontal and vertical components of the circulation system of ocean waters that is produced by gravity, wind friction, and water density variation in different parts of the ocean. Ocean … WebIn the case of the Oregon coast, southward blowing winds create upwelling-favorable conditions, where surface water flows to the right of the wind away from the shore. When these conditions occur, deep water then rises, or upwells, to the surface to replace the water moving offshore.
