4. I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling 4 Pesqueclima Evaluate the impact of climate variability in social and economical vulnerability of communities that fish shrimp in the estuarine region of dos Patos Lagoon; Provide climate forecasting design- ed to the needs of those com- munities, and contingency plans to climate situations that are not ade- quate to perform their economical activities.

33. I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling 33 Extreme Events of Precipitation in Rio Grande Observed precitation in Rio Grande is not always that of the drainage area in NCDC. Spatial and temporal patterns are simulated well by RegCM3 in most events; Mensal forecast errors often exceed ±5-30%. Errors decrease in seasonal (3months) average, especially in SU2 region;

34. I Ibero-American Workshop on Climate Dynamics, Climate Change, and Regional Climate Modeling 34 Extreme Events of Precipitation in Rio Grande Error in region SU1 for seasonal average is high, due to boundary distance. Gas parameterization produces errors smaller or equal to Gfc ones. The analysis should be extend to establish a better representation of cumulus convention in the southern region of Brazil.
