High Resolution Model development Scientific Goals: Simulated variability and predictability is likely a function of the model Developing improved models (higher resolution, improved physics, reduced bias) is crucial for studies of variability and predictability Explore ocean’s role in climate variability and change using a high resolution coupled model.

Weather Climate Connection Improved regional forecast capabilities of U.S. temperatures and precipitation from a week to a season. Climate prediction capabilities for high-impact events, including droughts and major floods. Enhanced data sets and analyses to identify and interpret weather-climate connections between the tropics and mid- latitudes. Improve understanding and predictions of connections between climate variations and high impact weather phenomena (droughts, floods)‏
