| Abstract: | Based on the advective-turbulent transport equation of heat of the infrared radiation and the water-vapor advective-turbulent diffusion equation together waith their corresponding definite conditions, a two-layer model of simulated sea fog is proposed.This model differs from the Barker's model in that the turbulent boundary layer is not treated as a constant flux layer but the temperature and the moisture of this layer are considered to be affected by turbulence advection and infrared radiation. Furthermore, according to the characteristics of the weather process of sea fog formation, an analytical solution is given after the nonlinear terms of the equations are treated.Finally, the contributions of each physical factor to the temperature and the moisture of the forecast point are computed and discussed. |
