The mean kinematic and thermodynamic structures of tropical cyclones (TCs) making landfall in mainland China are examined by using sounding data from 1998 to 2009. It is found that TC usually accompanied with a decrease low-level wind speed, an expansion the radius strong wind, weakening upper-level warm core, drying mid-tropospheric air. On average, core TCs dissipates 24 h after landfall. height maximum base stable layer both increase increased distance center; however, former always higher than latter. In particular, asymmetric structure found. across various areas circulation differ, especially over left-front right-rear quadrants (relative direction motion). quadrant, winds locate at smaller radius, temperature warmer extending into deep layer, while wet air occupies shallow layer. dwell area broader deeper, warmest situated farther away center.
