During the last three decades many hydrometeorological field and numerical studies have been done in the Amazonia region by researchers from Brazil, Europe, and the United States. This conference session invites contributions related hydrometeorological processes in the Amazonia region. Contributions are welcome to report on analyses and interpretation of historical data sets. Results from numerical modeling studies are particularly welcome. Conference presentations that evaluate the water budget components and address the physical mechanisms involved in precipitation recycling in the Amazon basin are highly encouraged. Findings from studies that report on the interactions between surface processes and the hydrologic cycle, and effects of climate change and drought on the precipitation processes in the Amazon basin are of great interest.
