Multi-scale wavelet analysis of TOPEX/Poseidon altimeter significant wave height in eastern China seas

The multi-scale characteristics of wave significant height （Hs） in eastern China seas were revealed by multi-scale wavelet analysis. In order to understand the relation between wave and wind, the TOPEX/Poseidon measurements of Hs and wind speed were analyzed. The result showed that Hs and wind speed change in multi-scale at one-, two-month, half-, one- and two-year cycles. But in a larger time scale, the variations in Hs and wind speed are different. Hs has a five-year cycle similar to the cycle of ENSO variation, while the wind speed has no such cycle. In the time domain, the correlation between Hs and ENSO is unclear.

波浪的多尺度的特征在东方中国海的重要高度(H_s ) 被多尺度的小浪分析揭示。以便理解在波浪和风之间的关系， H_s 和风速的 TOPEX/Poseidon 大小被分析。Theresult 显示出那 H_s 和风速变化在在一个点多尺度 -- ，二月，一半 -- ，一个 --andtwo 年周期。但是在一更大的时间可伸缩，在 H_s 和风速的变化是不同的。H_shas 类似于 ENSO 变化的周期的一个五年的周期，当风速没有如此的周期时。在时间领域，在 H_s 和 ENSO 之间的关联是不清楚的。
