Title: Hierarchical Spatio-Temporal Models for Nowcasting Radar Precipitation
Author(s): Christopher K. Wikle*+
Companies: University of Missouri
Address: Dept. of Statistics, Columbia, MO, 65211-0001,
Keywords: spatio-temporal ; meteorology ; radar ; dynamic ; image
Abstract:

For many hydrological applications, especially flash flood warning and urban drainage management, a good short-period forecast of heavy rainfall is required. However, the deterministic nowcasting of thunderstorm motion and development has proved a difficult problem in meteorology due to the short spatial and temporal continuity of convective systems. An approach is presented here that efficiently parameterizes spatio-temporal dynamic models in a hierarchical framework for nowcasting such physical processes as observed from radar reflectivity images.
