Predicting the Acceleration of Northward-Moving Tropical Cyclones Using Upper-Tropospheric Winds
Abstract
Inconsistent forecasting of the acceleration of northward-moving tropical cyclones entering the domain of the mid-latitude westerlies has been a longstanding weakness in tropical cyclone forecasting. The tracks of tropical cyclones traversing a relatively high-density data area of the western North Pacific have been analyzed to verify the acceleration phenomenon and to correlate the movement with features of the upper-tropospheric wind field. The resultant forecast technique is described and the results obtained with its use during the 1982 tropical cyclone season are presented.
