A one-dimensional parameterized numerical model is presented which depicts the physical conditions attendant with the use of helicopter downdrafts for the creation of temporary clearings in fog. The results generated by the numerical model are compared to the data available from helicopter downdraft experiments. An example is given of the application of the model for investigation of the utility of the helicopter downdraft fog clearing technique for a particular set of meteorological conditions. (Author)
