The influx of warmer and saltier Indian Ocean waters into the Atlantic—the Agulhas leakage—is now recognized to play an important role in global thermohaline circulation climate. In this study results a ⅞° simulation with Hybrid Coordinate Model, which exhibit augmentation leakage, is investigated. This increase leakage ought have impact on meridional oceanic volume heat transports Atlantic Ocean. Significant linear trends found integrated transport at 20°, 15°, 5°S correlate well decadal fluctuations leakage. augmented also seems be related latent flux observed along northeastern coastline Brazil since 2003. shows that precipitation Brazilian coast has been increasing 2005, same location regime shift for transport. suggests affects western boundary system tropical Ocean, directly coast.
