abstract = "This chapter examines the impacts of warm pool (WP) El Ni{\~n}o on the tropical cyclone (TC) genesis over the South China Sea (SCS) during 1965–2004. We check the relationships between WP El Ni{\~n}o and SCS TC genesis in Sept-Oct- Nov (SON) when the interannual variability of TC genesis is significant. Compared with the cold tongue (CT) El Ni{\~n}o, the relationship of TC genesis with WP El Ni{\~n}o is significant. In recent a couple of decades with more frequent WP El Ni{\~n}o, the significant coherent variations between TC genesis and WP NINO index on the timescales of approximately 4 years are displayed. The distinct different atmospheric teleconnection patterns related to CT and WP El Ni{\~n}o are responsible for these relationships. The WP El Ni{\~n}o could result in a dipolar pattern with anticyclone anomalies over the SCS and cyclone anomalies over the western tropical Pacific warm pool at low- and mid-level, which is different from the CT El Ni{\~n}o-induced anticyclone anomalies over the SCS and western tropical Pacific warm pool. These WP El Ni{\~n}o-related large-scale circulation anomalies could enlarge the low-level northerlies over the SCS, which consequently enhances the vertical wind shear and suppresses the TC genesis over the SCS.",
