摘要
为更好地揭示蒸发波导形成机理与近海面湍流通量的定量相关关系,基于海上平台实测水文气象数据,引入稳定条件以及不稳定条件下预测性能较好的P-RSHMU蒸发波导模型,定量给出该模型预测蒸发波导高度与近海面湍流通量的相关分析。结果表明:P-RSHMU模型预测有效抑制了稳定条件下蒸发波导高度为40m的情形;针对所有数据(不区分稳定条件),该模型计算的蒸发波导高度与潜热通量相关系数为0.92,与动量通量相关系数为-0.41,与感热通量的相关系数为-0.12;区分稳定条件,得到3种情形下蒸发波导高度与潜热通量均呈现显著相关,相关系数均大于0.9。这些结果为丰富蒸发波导的形成机理以及内涵提供进一步的数据支撑。
In order to better reveal the quantitative correlation between the formation mechanism of evaporation duct and turbulent flux near the sea surface,the P-RSHMU evaporation duct model is introduced because of its good prediction performance under stable and unstable conditions.The correlation analysis between the height of evaporation duct predicted by P-RSHMU model and turbulent flux is quantitatively given based on the measured hydro-meteorological data collected by the offshore platforms.The results show that:the P-RSHMU model can effectively suppress the evaporation duct height of 40m under stable conditions.For all data(regardless of stability conditions),the correlation coefficient between evaporation duct height and latent heat flux calculated by this model is 0.92,the correlation coefficient with momentum flux is-0.41,and the correlation coefficient with sensible heat flux is-0.12.In the three cases,the height of evaporation duct is significantly correlated with the latent heat flux,and the correlation coefficient is greater than 0.9.These results provide further data support for enriching the formation mechanism and connotation of evaporation duct.
