Abstract:

The impact of the satellite-sensed winds on the intensity forecasts of tropical cyclones is evaluated by a simulation study with an axisymmetric numerical model. The parameterized physics in the forecast model are deliberately made different from those in the model that generates the observation. The inital wind errors for the forecasts are systematic assumed to be caused entirely by the non-divergent, static initialization. Model generated observations are assimilated into forecasts by a 12h dynamic initialization. Author
