南海海浪场与厄尔尼诺的相关性分析
The relationship between El Nino and wave field in the South China Sea
摘要
Abstract
Based on the ERA-40 wind field data and wave reanalysis data in the past 45 years, the relationship between El Nino events and wave in the South China Sea was analyzed. The results show that: (1) there is a close relationship between nino3 index and wave in the South China Sea, whereas the correlation of swell wave and mixed wave is closer than the wind wave with nino3 index. The relationship between nino3 index and wave in Ju-ly and October is better than that in January and April. (2) The first modes of sea surface wind field, wind wave, swell wave and mixed wave have a similar spatial characteristic, which presents a high to low value distribution from northeast to southwest. (3) The periods of sea surface wind field, wind wave, swell wave and mixed wave exist 3-3.75 years in the South China Sea. The common period of the sea surface wind field, wind wave and the nino3 index is 3,3 years and 5years, while the swell wave, mixed wave and nino3 index have the common period of 3-4 years关键词
