Lead-lagged regression and ocean surface-layer temperature balance analyses were performed to contrast their control mechanisms. Type-1 variability is part of the canonical, which is characterized by SST anomalies extending from the South American coast to the central Pacific, is coupled with the Southern Oscillation, and is associated with basinwide subsurface ocean variations. This type of variability is dominated by a major 4-5-yr periodicity and a minor biennial (2-2.5 yr) periodicity. In contrast, Type-2 variability is dominated by a biennial periodicity, is associated with local air-sea interactions, and lacks a basinwide anomaly structure. In addition, Type-2 SST variability exhibits a strong connection to the subtropics of both hemispheres, particularly the Northern Hemisphere. Type-2 SST anomalies appear first in the northeastern subtropical Pacific and later spread toward the central equatorial Pacific, being generated in both regions by anomalous surface heat flux forcing associated with wind anomalies. The SST anomalies undergo rapid intensification in the central equatorial Pacific through ocean advection processes, and eventually decay as a result of surface heat flux damping and zonal advection. The southward spreading of trade wind anomalies within the northeastern subtropics-to-central tropics pathway of Type-2 variability is associated with intensity variations of the subtropical high. Type-2 variability is found to become stronger after 1990, associated with a concurrent increase in the subtropical variability. It is concluded that Type-2 interannual variability represents a subtropical-excited phenomenon that is different from the conventional ENSO Type-1 variability.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">ISI:000278783300004</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;ISI Document Delivery No.: 611ARTimes Cited: 3Cited Reference Count: 36Cited References:      AN SI, 2004, J CLIMATE, V17, P2399     ANDERSON BT, 2003, J GEOPHYS RES-ATMOS, V108, ARTN 4732     ASHOK K, 2007, J GEOPHYS RES-OCEANS, V112, ARTN C11007     BARNETT TP, 1991, J CLIMATE, V4, P269     BATTISTI DS, 1989, J ATMOS SCI, V46, P1687     BJERKNES J, 1966, TELLUS, V18, P820     BJERKNES J, 1969, MONTHLY WEATHER REV, V97, P163     CHANG P, 2007, GEOPHYS RES LETT, V34, ARTN L16608     CHIANG JCH, 2004, J CLIMATE, V17, P4143     GU DF, 1995, J CLIMATE, V8, P864     JIANG N, 1995, CLIM DYNAM, V12, P101     KALNAY E, 1996, B AM METEOROL SOC, V77, P471     KAO HY, 2009, J CLIMATE, V22, P615, DOI 10.1175/2008JCLI2309.1     KIM SB, 2007, J CLIMATE, V20, P3822, DOI 10.1175/JCLI4206.1     KOHL A, 2006, 40 ECCO     KUG JS, 2009, J CLIMATE, V22, P1499, DOI 10.1175/2008JCLI2624.1     LARKIN NK, 2005, GEOPHYS RES LETT, V32, ARTN L16705     LEE T, 2003, J CLIMATE, V16, P4022     MCCREARY JP, 1994, J PHYS OCEANOGR, V24, P466     MCPHADEN MJ, 2002, J CLIMATE, V15, P2632     MEEHL GA, 2001, GEOPHYS RES LETT, V28, P1731     MEEHL GA, 2002, J CLIMATE, V15, P722     RASMUSSON EM, 1982, MON WEA REV, V110, P354     RASMUSSON EM, 1990, J MARINE SYST, V1, P71     RAYNER NA, 2003, J GEOPHYS RES-ATMOS, V108, ARTN 4407     SCHOPF PS, 1988, J ATMOS SCI, V45, P549     SUAREZ MJ, 1988, J ATMOS SCI, V45, P3283     TRENBERTH KE, 2001, J CLIMATE, V14, P1697     VIMONT DJ, 2003, J CLIMATE, V16, P2668     WANG B, 1996, J CLIMATE, V9, P1586     WEBSTER PJ, 1992, Q J ROY METEOR SOC, V118, P877     YE ZQ, 2008, J CLIMATE, V21, P5745, DOI 10.1175/2008JCLI1580.1     YU JY, 2001, J CLIMATE, V14, P2329     YU JY, 2007, J GEOPHYS RES-ATMOS, V112, ARTN D13106     YU JY, 2009, J CLIMATE, V22, P1850, DOI 10.1175/2008JCLI2706.1     ZHANG Y, 1997, J CLIMATE, V10, P1004Yu, Jin-Yi Kao, Hsun-Ying Lee, TongNsf [atm-0925396]; nasa [nnx06af49h]; jpl [1290687]We thank two anonymous reviewers and Dr. Shang-Ping Xie for their constructive and helpful comments.
