A COMPARISON BETWEEN GEOSTROPHIC AND NONGEOSTROPHIC NUMERICAL FORECASTS OF HURRICANE MOVEMENT WITH THE BAROTROPIC STEERING MODEL
Publisher: American Meteorological Society
Abstract: The steering flow of a hurricane is obtained by eliminating the vortex pattern from the total flow field. The evolution of the steering flow is predicted by solving the barotropic nondivergent vorticity equation. Based ...
THE NUMERICAL PREDICTION OF HURRICANE MOVEMENT WITH A TWO-LEVEL BAROCLINIC MODEL
Publisher: American Meteorological Society
Abstract: A steering method of predicting hurricane movement is formulated based upon a two-level baroclinic model. The upper steering-flow field is constructed from the pressure-weighted mean of the 200- and 500-mb steering-height ...
A NUMERICAL EXPERIMENT ON THE DEVELOPMENT OF A TROPICAL CYCLONE
Publisher: American Meteorological Society
Abstract: A model of a tropical cyclone is constructed which is based upon conservation of momentum, mass,water vapor and heat in the hydrostatic system. The horizontal and vertical eddy-exchange processes for momentum, moisture and ...
THE NUMERICAL PREDICTION OF HURRICANE MOVEMENT WITH THE BAROTROPIC MODEL
Publisher: American Meteorological Society
Abstract: In order to increase the accuracy of prediction of hurricane movement beyond that which has been obtained with methods now in use, a numerical procedure based upon the barotropic model is presented here. A vortex field is ...
