ANALYSIS OF THE CLIMATIC CHARACTERISTICS OF LANDING TROPICAL CYCLONES IN EAST CHINA

The intensity, landing time, track trend and intensity variation of tropical cyclones (TCs) after landfall are analyzed using the TCs data (of best track from the China Meteorological Administration) between 1949 and 2006 for the western North Pacific and South China Sea. The trend differences of track and intensity between the TCs that directly land in East China and those making the second landfall in East China after landing in Taiwan Island are categorically discussed. The results show that the first kind of landing TCs are more likely to go northward or turn while the second kind of TCs have a larger tendency to keep going northwest. The intensity of the first kind of TCs is more persistent than the second one. There is a higher percentage for the intensity to be weakened significantly if the TCs keep going west to northwest or southwest after landing.
