Última The Influence of Pacific SST on the Precipitation over Southern Africa Diagnosed from an AGCM OceanDocs Misra, V.. This study is an analysis of AGCM model results to understand the dynamics of the response of precipitation over southern Africa (SA) to anomalies in the sea surface temperature (SST) over the Pacific Ocean. The dipole pattern of interannual precipitation anomaly over SA and its temporal variations are quite similar in both the ensemble mean of the control (where the AGCM is forced with observed SST’s in all ocean basins) and experimental runs (where the AGCM is forced with seasonally varying climatological SST over the Pacific Ocean). However the amplitude of the variability is found to be relatively reduced in the experimental runs. This is shown to be a result of the modulation of the Walker circulation by the variability of Pacific Ocean SST. The...

Ano: 2002 URL: http://hdl.handle.net/1834/501 The Teleconnection between the Western Indian and the Western Pacific Oceans OceanDocs Misra, V.. In this study we show a teleconnection pattern relating Outgoing Longwave Radiation (OLR) anomalies over the western Pacific Ocean and sea surface temperature anomalies (SSTA) over the western Indian Ocean over two seasons (Sept-Oct-Nov and Dec-Jan-Feb) at zero lag from observations and atmospheric general circulation model (AGCM) integrations. This teleconnection pattern suggests that a positive SSTA in Sept-Oct-Nov (SON) and Dec-Jan-Feb (DJF) seasons over the western Indian Ocean increases the contemporaneous positive OLR anomalies over the western Pacific Ocean. This teleconnection pattern is also simulated by the Center for Ocean-Land- Atmosphere studies (COLA) AGCM forced with observed SST’s. From the experimental COLA AGCM runs (wherein the Pacific...
