How are ocean currents related to global circulation? What three things affect surface currents? ocean currents can be generated by wind,density and differences in water masses caused by temp. These currents are on the oceans surface and in its depths, flowing both locally and globally. eastern currents are the opposite slow shallow and wide and move cold water towards the equator. Ocean currents influence the climate and economic activities of coastal regions in the following ways: Warm currents raise the temperature along the coast, while cold currents drop the temperature along the coast. Surface Currents. Ocean currents are driven by wind, water density differences, and tides.Oceanic currents are driven by three main factors: The different types of currents (referred to as surface or thermohaline, depending on their depth) are created by, among other things, wind, water density, the topography of the ocean floor and the coriolis effect.
