英文摘要: This study investigates how tropical cyclone (TC) tracks and landfalls are modulated by the two major components of the intraseasonal oscillation (ISO), the 30-60-day Madden-Julian oscillation (MJO) and the 10-20-day quasi-biweekly oscillation (QBWO). In the convective phases of the MJO(phases 7+8 and 1+2), the western North Pacific Ocean (WNP) is mainly clustered with westward- and northwestward-moving TCs. The strong easterlies (southeasterlies) in the southern flank of the subtropical high lead to an increase in TC activity and landfalls in the Philippines and Vietnam (China and Japan) in phase 7 +8 (phase 1+2). In the nonconvective phases (phases 3+4 and 5+6), TCs change from the original straight-moving type to the recurving type, such that the tendency for landfalls is significantly reduced. The QBWO, on the other hand, has a significant influence on TC landfalls in the Philippines and Japan. The strengthening of the subtropical high in phase 1+2 favors the development of westward-moving TCs and results in an increase in landfalls in the Philippines, while in phase 3+4 (phase 5+6), there is an increase (decrease) in TC activity and landfalls in Japan because of changes in genesis locations and large-scale circulations. The results herein suggest that both the MJO and QBWO exert distinctive impacts on TCs in the WNP. © 2013 American Meteorological Society. Citation statistics:
