Radiation Fog Modeling.

Abstract

The radiation fog model is being developed in an attempt to predict the initiation, development and characteristics of these fogs. The model is primarily based upon three important processes which interact to determine whether a fog will form in preference to haze development and what characteristics and fluctuations are likely to accur if a fog does form. These processes are: (1) Radiative exchanges; (2) Droplet growth and CCN spectra; and (3) Turbulence characteristics. The exact nature of these interactions is poorly understood and consequently have not yet been fully included in existing models. To date, therefore, accurate simulation of all fog characteristics on various temporal and spatial scales has not been achieved. Data from recent field studies, especially Meppen, have produced results which will enable not only the model to be fully tested, but also greatly assist in the understanding of radiation fog, which will in turn allow more accurate and detailed models to be developed.
