Abstract: The climatological structure in the upper-tropospheric summertime circulation over South America is diagnosed using a GCM (with and without South American topography), a linear model, and observational data. Emphasis is ...

Abstract: The regional precipitation climatology of South America during austral summer is studied by means of an R30 general circulation model (GCM). Results from perpetual January experiments, which differ only in their distributions ...

Abstract: The observed large-scale circulation mechanisms associated with summertime precipitation variability over South America are investigated. Particular attention is paid to the Altiplano where a close relationship has been ...

Abstract: eedbacks between ice extent and evaporation have long been suspected to be important for Lake Superior evaporation because it is during autumn and winter when latent heat fluxes are highest. Recent direct measurements of ...
