等效蒸发波导特征量最佳计算方案研究

Study On The Best Calculaton Scheme Of Equivalent Evaporation Duct Feature

针对现有等效蒸发波导特征量计算方案在我国海域适用性不足的问题,满足蒸发波导模型检验的需要,本文使用我国沿海实测探空数据,通过误差、标准差的比较,研究了J.F.Howell、S.P.Oncley以及G.J.Steeneveld等学者提出的3种计算方案在不同海域、不同季节的适用性。海域适用性结果表明:南海海域等效蒸发波导特征量的最佳计算方案为G.J.Steeneveld等的方案,而东海海域的最佳计算方案为S.P.Oncley等的方案;季节适用性结果表明,G.J.Steeneveld等的方案在春季的拟合效果最好,S.P.Oncley等的方案在夏、冬两季的拟合效果最好,为后续研究提供了理论基础。

In view of the lack of applicability of the existing equivalent evaporation duct featm＇e calculation scheme in China＇s sea area,and the requirement of the evaporation duct model test,this paper used the actual sounding data in China＇s coastal areas,and studied the applicability of the three computational schemes proposed by JF Howell,SPOneley and GJ Steeneveld in different sea areas and different seasons by comparing the error and standard deviation. The applicability- of the sea area shows that the best calculation scheme for the equivalent evaporating duct feature in the South China Sea is the scheme proposed by GJ Steeneveld et al.,while the optimal calculation method for the East China Sea is the scheme proposed by SPOneley et al.;the seasonal applicability- shows that the scheme proposed by GJ Steeneveld et al.has the best fitting results in the spring,while in the summer and winter,the scheme proposed by SPOneley et al.fits best. These results provides a theoretical basis for the follow-up study.
