摘要: 提出了一种大气光学折射率结构常数的数值模式。通过解大气边界层风速、位温度、绝对湿度预报方程,表面热平衡方程和土壤热传导方程，得到地表温度、表面层的动量通量、显热通量和潜热通量。再由MoninObukhov相似理论，从湍流通量和温度结构常数的经验关系计算出折射率结构常数。Abstract: A numerical model of atmospheric optical refractive index structure parameter is presented. This model solves the set of prognostic equations of horizontal components of the wind, the potential temperature, specific humidity, an energy balance equation, and a soil heat conduction equation, to obtain the ground surface temperature, the surface flux of momentum, sensible heat, and latent heat. These fluxes are then used to calculate refractive index structure parameter by empirical relationships of turbulence flux and temperature structure parameter according to MoninObukhov similarity theory.
