有关海洋表层温度的叙述，正确的是( )

A．暖流流经海区的水温均高于寒流流经海区

B．洋流可增大高、低纬度海区之间的水温差异

C．热量辐射是各纬度海区之间热量交换的主要方式

D．水温的年变化幅度近岸海区大于同纬度大洋中部

答案

答案：D

A项是错误的，因为暖流与寒流是相对而言的；暖流从低纬向高纬流动，洋流的温度高于所流经海区的海水温度，寒流从高纬流向低纬，其温度低于流经海区的海水温度。根据海水温度随纬度的变化规律可知，即使低纬度海区的寒流，温度也高于高纬度海区的暖流。洋流在低纬和高纬之间流动，使高低纬度之间不断进行着热量输送和交换，从而减小其温差，故B、C两项错误。在近岸海区，由于海水温度受陆地的影响比较明显，故水温的年变化幅度大于同纬度的大洋中部，故D项正确。
