【考点归纳】一、洋流的主要规律1.洋流分布规律(1)中低纬海区洋流分布规律:在中低纬海区,形成了以副热带(30°)为中心的反气旋型(北半球是顺时针,南半球是逆时针)的大洋环流(如下图)。太平洋与大西洋洋流分布规律最典型,印度洋只在南半球有所体现。(2)中高纬海区洋流分布规律:在中高纬海区,形成了以副极地(60°)为中心的气旋型(北半球为逆时针,南半球实际不存在)大洋环流(如下图)。
【Test Points Induction】 I. Main regularities of ocean currents 1. Current law of ocean current (1) Current distribution in mid-low latitude sea area: In the middle and low latitudes, the anticyclone (30 °) is the anticyclone Hour hand, counterclockwise in the southern hemisphere) (as shown below). The distribution of the Pacific and Atlantic currents is most typical, and the Indian Ocean is only reflected in the southern hemisphere. (2) The ocean current distribution in mid-high latitudes: In the middle and high latitudes, the oceanic circulation centered on the subpolar (60 °) is formed (anticlockwise in the northern hemisphere and virtually absent in the southern hemisphere) (see below).
