Summer Regime Nonrecurvature Pattern Figure A.9 is indicative of a nonrecurvature situation. When the Asian upper level anticyclone remains east of a TC, the TC will exhibit a greater westward than northward component of movement, and recurvature will not occur. Such TCs commonly affect the southern Ryukyu Islands, Taiwan, and the People's Republic of China. List of Figures of Appendix A Figure A.1 .
