rossby波临界周期与海面高度异常能谱临界周期在南海的空间分布特征
Keywords: 临界周期,南海,？,rossby波,ssha能谱,风应力旋度
Abstract:
？本文利用woa01(thewordoceanatlas2001)海水各层气候态温盐数据计算南海rossby波临界周期,并与其在同纬度西北太平洋中的分布对比。结果显示,在南海中rossby波临界周期随纬度增加而逐渐增加,并且由于南海的特殊地形,海盆中rossby波临界周期呈北东—南西向分布,与其在大洋中呈纬向带状分布不同。通过分析南海各网格点上海面高度异常(ssha,theseasurfaceheightanomaly)的能谱,我们发现在海盆中部其临界周期与当地rossby波临界周期基本相同,其值也随纬度增加而逐渐增加,因而从观测上验证了模式结果,即在海面风应力旋度能谱临界周期小于等于当地rossby波临界周期的条件下,海洋响应能谱临界周期等于当地rossby波临界周期。
