摘 要:
在利用改进的POM模式的基础上，嵌套西北太平洋区域模式HAMSOM结果，建立1个日本海对马海峡海域斜压准预报模式。通过与已有的观测和研究进行对比，得到较为可信的模拟结果。以温度场和盐度场为参考，系统分析讨论该海域的环流结构及其季节变化。对于温度锋和盐度锋的位置，以及对马暖流的流核等存在争议的问题给出了相应的解释。对马海峡作为日本海的上层水体主要输入区域，对马暖流携带的高温高盐水经过该区域时，在温盐等方面呈现出自南向北的递减变化趋势。对马暖流被对马岛分为东西两支，流核深度随季节变化，并且明显存在双核结构。[著者文摘]

Abstract:
In this paper, based on an improved POM model, by nesting the results of the HAMSOM model, a baroclinic quasi prognostic model is built for the Tsushima Strait （TS）. The high resolution and long time series of temperature, salinity and circulation are numerically simulated. The results well compare well with observational data and former investigations. This paper also expounds some issues of wide interest, such as the seasonal variation of the temperature, salinity, circulation and the paths of current across the TS in to the Japan sea （JS）. The results of the model show that the current flowing into the JS through the TS, bringing warm and saline water, is mainly divided into western and eastern branches, the East Korean Warm Current （EKWC） and the Japanese Coast Branch （JCB, referred as the Nearshore Branch in the Japanese literature）, respectively. The main axis of the current at the TS in the JS changes its depth as the season changes, and it obviously has a double-core structure.[著者文摘]
