Strategies for Coupling Global and Limited-Area Ensemble Kalman Filter Assimilation
This thesis compares the forecast performance of four strategies for coupling global and limited area data assimilation: three strategies propagate information from the global to the limited area process, while the fourth ...
IMPROVING U.S. EXTREME PRECIPITATION PREDICTION AND PROCESS UNDERSTANDING USING A MESOSCALE CLIMATE MODEL MULTI-PHYSICS ENSEMBLE APPROACH
Despite many recent improvements, climate models continue to poorly simulate extreme precipitation. I attempted to improve prediction of extreme precipitation, focusing on daily 95th percentile (P95) events, and to better ...
A New Quantitative Framework for Application of Ensemble Forecast Sensitivity to Observations in NWP
Current global operational Numerical Weather Prediction (NWP) systems (e.g.the National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS)) generally assimilate on the order of 10 million observations ...
