英文摘要 | Interdecadal variability of tropical cyclone (TC) genesis in the South China Sea (SCS) during 1982-2015 is investigated using observations and atmospheric reanalysis data. TC genesis primarily occurs in the northern SCS (north of 13 degrees N) in July-September (summer), while in the southern SCS (south of 13 degrees N) in October-December (autumn). The TC genesis location is consistent with the climatological distribution of TC genesis potential index. Noticeably, the TC genesis frequency (TCGF) is relatively low in 1982-1993 and 2003-2015 while relatively high in 1994-2002 in summer in the SCS. In autumn, the TCGF shows an abrupt transition from high to low in the early 2000s in the SCS. It is found that such interdecadal change of TCGF is closely related to the east-westward movement of the subtropical high (SH). When the SH is close to the SCS, large-scale air subsidence, low-level divergence, negative vorticity, and high pressure are prominent and inhabit TC genesis in the SCS. On the contrary, when the SH moves away from the SCS, environmental conditions become more favorable for TC genesis. In addition, the localized atmospheric intraseasonal variability can affect TCGF at interdecadal time scales as well. |
