TL;DR: In this article, two atmospheric general circulation models, differing in numerics and physical parameterizations, are employed to test the hypothesis that El Nino-induced sea surface temperature (SST) anomalies in the tropical Indian Ocean impact considerably the Northern Hemisphere extratropical circulation anomalies during boreal winter [January-March +1 (JFM +1)] of El NINO years.

TL;DR: In this paper, the authors investigate the possible reason for the occurrence of strong IODZM events in these two decades, namely, the hypothesis that the mean thermocline in the EEIO is raised or lowered depending on the phase of Pacific decadal variability (PDV), preconditioning it to favor stronger or weaker IODM activity.

TL;DR: The simulation characteristics of the Asian-Australian monsoon are documented for the Community Climate System Model, version 4 (CCSM4) as discussed by the authors, which is the first part of a two part series examining monsoon regimes in the global tropics in the CCSM4.

TL;DR: In this article, the authors investigated the effect of regional SST anomalies (equatorial Indian Ocean and Indonesian seas) on the amplitude of the developing El Nino in the Indian Ocean Dipole Zonal Mode (IODZM).

TL;DR: In this paper, detailed Madden-Julian oscillation (MJO) characteristics in the two 30-day integrations of the global cloud-system-resolving Nonhydrostatic Icosahedral Atmospheric Model (NICAM) using the all-season real-time multivariate MJO index of Wheeler and Hendon were revealed.
