摘要
通过分析新的SODA资料,得到西北太平洋上层海表温度时空分布特征,剖析了西北太平洋海表温度的季节变化及经纬向分布特征,得出西北太平洋声速值变化规律。资料分析表明:西北太平洋海表温度存在着显著的季节变化特征。在季节变化中,春季由于太阳辐射加强,使整个海域海表温度比冬季约高2℃,整个西北太平洋东南部SST等温线分布较为平缓;夏季SST受太阳辐射的影响而整体升高,分布均匀且南北温差较小;秋季海表温度开始降低;冬季海表温度整体降低,等温线达到全年最低,南北温差较大。海表温度基本上是纬向分布,低纬海洋温度在20～30℃之间,高纬海洋降至0～1℃,等温线在中纬度(40°N附近)最密集,南北温度梯度最大。
Based on the new Simple Ocean Data Assimilation （SODA）data, the characteristics of the seasonal and interannual variations of the sea surface temperature（SST）in the Western North Pacific （WNP）Ocean are derive＆ There is a distinct characteristic of the seasonal variations of the sea surface temperature in the WNP. Generally, in spring, as the solar radiation strengthens, the SST of the entire sea is higher than the winter, the distribution of the SST isothermal is gently in northwest WNP; in summer, the SST rises continuely and distribut gentlly; in autumn, the temperature starts to lower; in winter, the surface temperature is lower in the entire sea, the temperature isothermal is the lowest in the year, there is a distinct difference between north and south ocean of the surface temperature The SST basicly along latitude in WNP, it is between 20-30℃ in the low latitude ocean, it reduce to 0-1℃ in the high latitude The isothermal in the middle latitude is dense than other places, and also the north and south temperature gradient is maximum in the entire ocearL
