Advance the Cutting-Edge Science and Technology in Radar and Satellite Data Assimilation for Analyses and Predictions of Severe Storms and Tropical Cyclones
Abstract
Funds are provided to investigate radar and satellite data assimilation (DA) for analyses and predictions of severe storms and tropical cyclones (TCs). The proposed effort will combine new innovations with advanced theory to address issues in radar and geostationary satellite DA that are important for analyzing and forecasting severe storms and TCs worldwide. The proposed research has three objectives. 1) Explore and develop new theoretical formulations and analysis techniques to retrieve upper-tropospheric vortex winds from geostationary satellite rapid infrared scans of TCs. 2) Develop advanced variational methods with improved flow-dependent background error covariance formulations to retrieve the primary vortex winds and the secondary vertical circulations in TCs from radar observations in combination with geostationary satellite rapid infrared scans. 3) Use the above retrieved vortex winds in combination with all-sky infrared brightness temperature observations from geostationary satellites to improve DA and storm and TC intensity predictions. New methods and capabilities gained through the proposed research will advance radar and satellite DA to improve predictions. Transitions of newly gained knowledge and capabilities will be accomplished through collaboration with scientists at the Marine Meteorology Division of Naval Research Laboratory to provide innovations to the Navys meteorological operations.
