中文摘要	This study examines the impact of the cold tongue (CT) El Nino and the warm pool (WP) El Nino on tropical cyclone (TC) genesis over the South China Sea (SCS) from 1965 to 2010. During Sept-Oct-Nov (SON), the TC genesis exhibits clear interannual variability. SON TC genesis is significantly related with the WP Nino index, but not with the CT Nino index. It is found that in the past two decades the SCS TC genesis varies coherently with the WP Nino index on a timescale of approximately 4years, which is in accordance with the recent increase in WP El Nino events. The distinctly different atmospheric teleconnection patterns related to the CT and WP El Nino over the SCS are responsible for these relationships. CT El Nino can induce anticyclone anomalies over the SCS and the western tropical Pacific WP. However, WP El Nino can result in dipolar patterns with anticyclone anomalies over the SCS and cyclone anomalies over the western tropical Pacific WP at low- and mid-level. These WP El Nino-related large-scale circulation anomalies enlarge the low-level northerlies over the SCS. This in turn enhances the vertical wind shear and thus suppresses TC genesis over the SCS.
