Comparison between predicted and experimental result of regional evaporation duct over sea

A platform for predicting the atmospheric duct is established based on the MM5 mesoscale model. We make use of the global forecasting system (GFS) data to predict the area sea surface evaporation duct including the Yellow sea area and the East China Sea and the South China Sea. An experiment was conducted on December 2015, and in the navigation we recorded the height of evaporation duct in different time and at different locations. A comparison between the measured data and predicted data is demonstrated that both of them have the same changing trend. This illustration confirmed the validation of the numerical predicted results of evaporation duct. Considering the advantage of high time resolution for measured method and large area for prediction method, we should use both of them in evaluating the performance of radar on the warship then we can derive the microwave propagation predicted effects over the sea.
