Statistical Analysis on the Multi level Steering Flows and Sudden Changes in Speed and Direction of Tropical Cyclones Movement[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 1996,35(S1):173-179.DOI:
We make statistics on 29 cases of tropical cyclone and analyse the relationship between the multi level steering flow (MLSF) and the speed and direction (including their sudden changes) of tropical cyclone movement. The results show that the MLSF is more indicative than a single lever streering level flow. The direction of MLSF approaches relatively the direction of tropical cyclones movement. Furthermore
the change in speed of MLSF closele relates to that of tropical cyclone. When the speed of MLSF is weak and its direction is varible
sudden changes in the speed or direction of tropical cyclone will occur frequently.
