摘要
蒸发波导是近海面经常出现的大气结构。从湍流运动方程出发,基于近海面海-气耦合湍流通量理论和算法分析了蒸发波导机理。对气象要素变化时,蒸发波导高度和感热、蒸发潜热和动量通量间的关系进行了分析,表明蒸发波导的形成和湍流通量具有明显相关性,为蒸发波导机理研究提供了新途径。
Evaporation duct is ubiquitous atmosphere structure near the sea surface. From the turbulent equation, based on the theory and algorithm of air-sea interface turbulent fluxes, the mechanism of evaporation duct is analyzed. Impacts of different meteorological elements on evaporation duct, the relation of the evaporation duct height to the variations of latent heat, sensible heat and stress fluxes are analyzed. The results indicate that the form of evaporation duct is directly related to turbulent fluxes, which give a new way to research the mechanism of evaporation duct.
