摘要: 目前,计算近地层湍流热交换的既简便又精确的公式还很少。本文根据J.A.布辛格(Businger)提出的普适函数求得一个计算湍流热交换和蒸发耗热的实用公式,其计算结果与利用布辛格普适函数所作的计算是相当一致的,而且计算方法简单,可供实际工作使用。

Abstract: It is usually difficult to calculate the turbnlent fluxes of sensible heat and laten heat near the ground by means of H=ρCpKu*12)/∫Z2фn/Z1Z dz (1) LE=ρCpKu*(q1-q2)/∫Z2фo/Z1Z dz (2) in which is called the universal function. Therefore, in this paper, we have developed an empirical formula for calculating the turbulent fluxes of sensible heat and latent heat to meet the requirements of practical use, which is based on the universal function sugge sted by J.A.
