太平洋赤道潜流起源的模式研究A Study on a Model of Origin of Pacific Equatorial Undercurrent
吕艳,王庆业
摘要(Abstract):
基于一个高分辨率准全球海洋模式HYCOM(HYbrid Coordinate Ocean Model),研究了热带西太平洋海域赤道潜流的起源。结果表明:赤道潜流在大约130°E处开始,流核位于225 m、2°N附近,最大流速超过15 cm/s,体积输运约1.6×106 m3/s,其水源来自棉兰老海流;在东部140°E断面,赤道潜流的北部主要是由棉兰老海流提供(9.7×106 m3/s),其南部主要是来自新几内亚沿岸潜流(9.1×106 m3/s)。
