There are 3.2 tropical cyclones (TCs) entering into the East China Sea on average every year. Recurvature or landfall of these TCs will make different effects. The comparative analysis on the situations and physical fields of recurving TCs and landfalling TCs shows that in the case of recurving TCs, subtropical high is weak and the east part of it is in massive shape; westerly belt is strong and close to TC; the middle and upper level westerly jets are significant and get intensified as they move eastward; the upper level divergence at the northeast of TC enhances while notable positive vorticity advection is found in the middle and low levels of TC with clear advection center. However, in the case of landfalling TCs, subtropical high is strong and in broad belt shape; westerly belt is weak and distant from TC; westerly jet is not notable and is not intensified; the upper level jet center is located in the northwest and north of TC; no remarkable upper level divergence occurs in the northeast of TC and the middle and low level positive vorticity advection is located in the northwest and north of TC with no notable advection center. The characteristics above can be seen 72 hours before the recurvature or landfall of TCs, and get much clearer in 48 hours before the events.
