Advancing Research on the Hydro-Climate of South America and the Caribbean

Session ID#: 160970

Session Description:
South America and the Caribbean play an important role in regional and global climate. Despite this, our understanding of the hydro-climate of South America and the Caribbean is limited largely due to the difficulty in adequately resolving via observations or model simulation the mesoscale phenomenon leading to the observed hydro-climate as well as its extremes. In this session, we invite abstracts on the South American and Caribbean hydro-climate, including studies using the recently performed Convective Permitting Climate Model simulations created with the Weather, Research and Forecasting (WRF) model organized by the SAAG group  to investigate the mesoscale factors impacting the hydro-climate for typical and extreme events in South America. At this point, we do not have Convective Permitting Climate Model simulations over the Caribbean but abstracts are still invited using available data.  In the future, we plan to conduct CPCM simulations over Central America and the Caribbean.

We also welcome research conducted within the CORDEX Framework for South America and the Caribbean. For both frameworks, we welcome abstracts describing research on the topics of land-atmosphere interactions, convective processes, orographic processes, observations and multi-model comparisons specific to South America and the Caribbean. This session is organized by the South America Affinity Group (SAAG).
