西北太平洋环流和海温数值模拟

摘要/Abstract

摘要： 基于Ecom-si建立了一个西北太平洋海洋数值模式,综合考虑了侧边界通量、海表面风应力、热通量、蒸发和降水等因素，模拟并分析了西北太平洋环流和海温的基本特征.模式验证结果表明，模式计算的海温与日本2008年西北太平洋实测温度走航断面资料吻合良好.模式再现了低纬度海区表层自东向西流动的北赤道流、强西边界流黑潮、东海的台湾暖流和对马暖流、黄海沿岸流和黄海暖流等.数值模式还较好地模拟出了西北太平洋、南海、东海和黄海的海温分布.

Abstract: Based on the ECOM-si, the circulation and temperature in the Northwest Pacific were simulated. The model includes the water flux at the lateral open boundaries, sea surface wind stress, heat flux, evaporation and precipitation at sea surface and so on. The model validation shows that the simulated sea temperatures are consistent with the section data, which were measured by Japan in the Northwest Pacific in each month of 2008. The model reproduces the North Equatorial Current, which flows westward at the surface in the low latitude Pacific, Kuroshio, which is a strong western boundary current, the Taiwan Warm Current and Tsushima Warm Current, the Coastal Current and Yellow Sea Warm Current and so on. In addition, the sea temperature distribution in the Northwest Pacific as well as in the South China Sea, East China Sea and Yellow Sea is also simulated by this model.

Key words: Northwest Pacific, sea temperature, circulation, numerical simulation
