摘要
利用高分辨率准全球海洋模式HYCOM(HYbrid Coordinate Ocean Model),采用局部加密网格的方法,模式积分30年,模拟了热带西太平洋环流的年平均状态和季节变化。通过与实测的海表面高度、测流资料、温盐资料等对比分析,验证了模拟结果的有效性,认为模式结果可以用于研究热带西太平洋潜流及其季节变化。
Annual mean status and seasonal variation of circulation in western tropical Pacific is simulated by using a quasi-global high-resolution ocean model HYCOM （HYbrid Coordinate Ocean Model）. The model used finer grid in some place, and was integrated for 30 years. By comparing with observations of sea surface height, velocity, and temperature and salinity fields, validity of modeling results is proved, and modeling results can be used to study undercurrents of western tropical Pacific and their seasonal variations.
