La Plata Basin Originated from sub-seasonal workshop focussing on link seamless prediction climate to weather

Motivation This plan is motivated mainly by the lack of comprehensive understanding about the processes that determine severe weather events in the La Plata Basin, and our limitation to provide skillful forecasts which would contribute to minimize their impacts. Severe storms, leading to floods, wind gusts, land-slides are frequent on this region, causing material damages and loss of lives. Increasing knowledge about such systems is vital for improving quality of early predictions and warnings, in order to mitigate their effects.

Main Goals To improve the assessment of state-of-art models ability to anticipate extreme weather conditions and to quantify their skill; To analyze the sources of model errors in order to feedback the development of models itself; To evaluate the impact of extra data in the quality of forecasts; To use TIGGE outputs and other available ensemble systems  to develop products/tools adequate for extreme weather forecast in the region and evaluate them in the operational context;

Nowcasting Role? . The National Weather Service of Argentina is starting to work on a nowcasting system, which is currently on its development phase. In Brazil, nowcasting techniques have been available and used, but more systematic and coordinated use would be desirable.
