A Kernel-Based Spatio-Temporal Dynamical Model for Nowcasting Weather Radar Reflectivities
用于天气雷达反射率即时预报的核时空动态模型
A good short-period forecast of heavy rainfall is essential for many meteorological and hydrological applications. Traditional deterministic and stochastic nowcasting methodologies have been inadequate in their characterization of pixelwise rainfall reflectivity propagation, intensity, and uncertainty. The methodology presented herein uses an approach that efficiently parameterizes spatio-temporal dynamic models in terms of integro-difference equations within a hierarchical…
