Currents are generated by winds, excessive cooling or evaporation at the ocean surface (thermohaline processes) and tidal forces. Wind-Driven Currents
WebMay 24, 2024 · When water returns to the ocean, it follows the path of least resistance, which is typically through these channels. Strong rip currents also often appear next to structures such as piers,... WebGeostrophic currents. For most of the ocean volume away from the boundary layers, which have a characteristic thickness of 100 metres (about 330 feet), frictional forces are of minor importance, and the equation of motion for horizontal forces can be expressed as a simple balance of horizontal pressure gradient and Coriolis force.This is called geostrophic …
