CLIMATE CHANGE - IRACEMA CAVALCANTI

REGIONAL CLIMATE MODELING – JEREMY PAL AND ROSMERI ROCHA

CLIMATE DYNAMICS

• Do we really know the mechanisms of the systems that affect the precipitation over South America (or North and Central America or Europa/Spain)?

• What are the uncertainties?• What do we need to improve our

understanding of those phenomena?• Do we need more collaboration? How

can we active this goal?

CLIMATE CHANGE

• Will the anomalies change in scenarios of climate change over South America?

• How the intensity of natural variability can change in the future?

• What are the best tools (numerical or stochastic models) to improve our understanding of the future scenarios?

• Despite of the uncertainties can we still aggregate value to the GCM outputs for the future scenarios?

REGIONAL CLIMATE MODELS

• Eta or RegCM3 or any other – positive and negative points – are there any real difference?

• Downscaling – Is it worthy doing?• What are the best tools that can be

used to validate the models?• Are there data to validated the models?

Which ones?• Others
