Our study indicates that the persistence barrier is significantly enhanced when both Pacific and Indian Ocean couplings are included in the CGCM, compared to the simulation that includes only the Pacific Ocean coupling. ENSO's variance, phase locking to the annual cycle, and biennial variability are also increased in the Indo-Pacific Run. Further analysis reveals that the overall amplitude of ENSO is not a primary factor in determining the strength of the persistence barrier, rather, it is the amplitude of the biennial component of ENSO affecting the barrier the most. The persistence barrier is consistently strong ( weak) when biennial ENSO variability is large ( small). No such a clear relationship is found between the strength of the barrier and the amplitude of the low-frequency ( 3 - 5 years) component of ENSO. This modeling study demonstrates that the biennial component of ENSO is one major mechanism responsible for the spring persistence barrier and that interactions between the tropical Pacific Ocean and Indian Ocean-monsoon could enhance the biennial component of ENSO.&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:000230833700005</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;ISI Document Delivery No.: 950BXTimes Cited: 8Cited Reference Count: 25Cited References:      BARNETT TP, 1984, MON WEATHER REV, V112, P2380     BRYAN K, 1969, J COMPUT PHYS, V4, P347     CHUNG C, 1999, J CLIMATE, V12, P2787     CLARKE AJ, 1998, J CLIMATE, V11, P987     CLARKE AJ, 1999, J CLIMATE, V12, P610     COX MD, 1984, 1 GEOPH FLUID DYN LA     GU DF, 1997, SCIENCE, V275, P805     KIM KM, 2001, GEOPHYS RES LETT, V28, P315     LAU KM, 1996, Q J ROY METEOR SOC B, V122, P945     LAU KM, 2001, J CLIMATE, V14, P2880     MECHOSO CR, 2000, INT GEOPHYS SER, V70, P539     NICHOLLS N, 1979, Q J ROY METEOR SOC, V105, P93     RASMUSSON EM, 1982, MON WEA REV, V110, P354     RASMUSSON EM, 1990, J MARINE SYST, V1, P71     RAYNER NA, 1996, 74 HADL CTR MET OFF, P1903     TORRENCE C, 1998, B AM METEOROL SOC, V79, P61     TORRENCE C, 1998, Q J ROY METEOR SOC B, V124, P1985     TROUP AJ, 1965, QUART J ROY METEROL, V91, P490     WAINER I, 1996, J GEOPHYS RES-OCEANS, V101, P25599     WANG B, 1996, J CLIMATE, V9, P1586     WEBSTER PJ, 1992, Q J ROY METEOR SOC, V118, P877     WRIGHT PB, 1979, NATURE, V277, P371     YU JY, 2001, J CLIMATE, V14, P2329     YU JY, 2002, GEOPHYS RES LETT, V29, ARTN 1204     YU JY, 2003, J CLIMATE, V16, P3072Amer geophysical unionWashington&lt;/p&gt;</style></notes><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;Univ Calif Irvine, Dept Earth Syst Sci, Irvine, CA 92697 USA.Yu, JY, Univ Calif Irvine, Dept Earth Syst Sci, Irvine, CA 92697 USA.jyyu@uci.edi&lt;/p&gt;</style></auth-address></record></records></xml>
