Ensemble forecasting and data assimilation in coupled systems Eugenia Kalnay Department of Meteorology and the Chaos Group University of Maryland
	• Ensemble forecasting, low dimensionality, and data assimilation. Examples with a QG model and the NCEP global model • Breeding, Lyapunov Vectors and Singular Vectors in a coupled system with fast and slow time scales. Examples with a coupled Lorenz model, Zebiak-Cane model and NASA coupled GCM (NSIPP) • Implications for data assimilation
