What are the two main ways in which ocean currents affect climates?

Ocean currents influence climates primarily through the redistribution of heat and the regulation of moisture. Warm currents, such as the Gulf Stream, transfer heat from the equator to higher latitudes, moderating temperatures and affecting weather patterns. Conversely, cold currents can cool coastal regions, leading to drier climates. Additionally, currents impact precipitation by influencing atmospheric circulation patterns, which can alter rainfall distribution.
