百余年全球海温的状态跃变分析

ANALYSIS OF STATE JUMP OF GLOBAL SST IN 1856～1991

应用刘桂馥（１９９５）〔１〕提出的递归相似（又称递归分解）方法，考查了百余年（１８５６～１９９１年）南、北半球太平洋、大西洋和印度洋海温季距平的状态跃变。发现在适当分辨率下。

In terms of the recursive similarity scheme proposed by Liu (1995), study was performed of the state jump of SSTA over the Pacific, Atlantic and Indian Ocean on a seasonal basis over the period 1856～1991. Results show that such jump has a quasi 10 year period if the resolution used is appropriate.
