Abstract

Investigates the pattern of Amazon Basin rainfall forecasts of 10 Global Weather Experiment cases. Although the computations are based upon a rather crude wavenumber 15 resolution, the control forecasts exhibit a rather fine structure of the rainfall over tropical S America, including enhancements over the interior of the Amazon Basin and suppression on the NE coast of Brazil. The sensitivity of this model forecast to the presence of anomalous E Pacific heating is investigated through experiments in which a nonadiabatic term is added to the thermodynamic equation. These experiments suggest significant suppression of rainfall over the central Amazon Basin, and especially over the NE portion of Brazil.-from Authors
