The surface southeast wind is a condition for the generation of advection fog, but it contributes to the disappearance of radiation fog. The inversion in the radiation fog is thick and strong ,but it is weaker or no inversion in the advection fog. The evolution of stratification from the occurrence to the destruction in the radiation fog is from stable to unstable, while the advection fog from unstable to stable.
