FORECASTING THE SPEED OF MOVEMENT OF SELECTED CYCLONES ALONG UPPER-AIR STEERING CHANNELS

Abstract

Following the selection of upper-air steering channels on the basis of the height of the ?closed? circulation, an objective technique is developed for forecasting the 24- and 30-hour displacements of surface ?lows.? Data used in forecasting the displacement are dependent on the selected steering channel and involve temperature gradients within these channels. Results on the original and test data-samples are compared with those of other similar investigations.
