What is it about?

Fog is one of the most important weather phenomena that occur in the low levels of the atmosphere. All the previous studies focused on a single fog type. This paper examines if a fog event can be of two different types during its spatial evolution ? and what are the factors influencing its life cycle over heterogeneous coastal area ?

Why is it important?

The most important finding of this work is that the same fog event can be of two different types, depending on the geographical standpoint, and that the physical processes involved in its spatial evolution are distinct. Besides, the life cycle of a coastal fog event is influenced by the sea surface temperature and the orography.

Perspectives

The fog prediction remains difficlut due to our incomplete understanding of the physical processes involved in fog. This paper demonstrates that a better numerical fog prediction over heterogeneous coastal area potentially depends on land topography and the accuracy of sea surface temperature in boundary conditions.
