| 摘 要： | 使用"中国ARGO实时资料中心"提供的2005—2009年连续5 a日本南部海域的ARGO浮标资料,通过建立标准层,统计并提取各标准层的剖面温度,采用AKIMA插值方法计算各层的温度梯度。较详细分析了该海域温度垂直剖面特征及温跃层的分布规律。在此基础上,使用分段三次多项式拟合方法建立了适用于该海区的温度垂直剖面模型,并利用2010年ARGO数据对模型进行了验证,研究表明,经过模型模拟的剖面温度与实测温度之间的相关系数可达到0.99以上。

| Abstract: | Using the Argo data provided by "China Argo Real Time Data Center" between 2005 and 2009,the distribution and evolvement of the thermocline in the north part of the First Island Chain was calculated and analyzed in detail by defining the standard layers,extracting the temperature of every layer and adopting the AKIMA interpolation method for temperature gradient calculation.On this basis,the models which are suitable for this area were built by cubic polynomial fitting method.Finally,ARGO data from 2010 were provided as the validation data,the study indicated that the models were credible enough for the correlation coefficients all above 0.99. |
