摘要
为了掌握黑潮的大范围流动结构以及它对气候的影响,利用三维原始方程模式MITgcm计算了西北太平洋海区的多年平均流态.模式结果在东海黑潮的路径、流速、流量等方面与多年来对黑潮的认识相一致.模式结果表明黑潮的体积输运春夏季较大、秋季最小,在东海PN断面黑潮体积输运年平均为29.7×106m3/s;黑潮对东中国海的热输送春季最大、秋季最小,年平均为0.058×1015W.这一量值与东中国海区海面热通量的总和具有相同的数量级.黑潮对东中国海区水温变化具有加速春季增温和减缓秋季降温的作用.
To get knowledge on Kuroshio large scale circulation and how the Kuroshio affects adjcent area climate, a three-dimension primitive equation ocean model MITgcm was used to simulate the kuroshio＇s climatological pattern. The results basically agree with former knowledge of the path, velocity, and volume transport. According to the climatological model results, the volume transport of Kuroshio is larger in spring and summer, and smallest in autumn. Annual mean of volume transport through PN section of the East China Sea is 29.7×10^6m^3/s. Heat transported to the East China Sea by the Kuroshio is largest in spring and smallest in autumn with annual mean of 0. 058×10^15W, at the same order of total sea surface heat flux of the East China Sea, which would accelerate warming and decelerate cooling of East China Sea water.
