中文摘要:

      文中采用一个边界层湍流模式估算海面上温度结构常数C_T²,模式输入的参数是气温、海表面温度和风速。模式估算的C_T²与1999年6月在东海实测的C_T²相当一致,此外,还对估算方法详细进行了敏感性分析。认为在估算C_T²时,对温度测量的精度要高,选用Thiermann公式比较好。

英文摘要:

      A model of atmospheric boundary layer was used to estimate C_T² over sea. The input parameters are air temperature,sea surface temperature and wind speed. A reasonable good agreement between the model predictions and the measurements of C_T² over the East China Sea can be found. A detailed sensitivity analysis of the estimation procedure has been made,showing that the accuracy of the C_T² estimate is dependent on the accuracy of the temperature measurement, and the V. Thiermann expression is better than Wyngaard's.
