Forecast improvement from radar data assimilation within the Rapid Update Cycle, Rapid Refresh, and High Resolution Rapid Refresh forecasts initialized with RUC/RR grids

In November 2008, a diabatic digital filter initialization (DFI)-based procedure for assimilating radar reflectivity data was implemented in the NCEP operational hourly updating Rapid Update Cycle (RUC). This marked the first operational use of WSR-88D mosaic reflectivity data in an NCEP model. This radar reflectivity assimilation procedure has ...

Assimilation of radar reflectivity data using a diabatic digital filter: Applications to the Rapid Update Cycle and Rapid Refresh and initialization of High Resolution Rapid Refresh forecasts with RUC/RR grids

A diabatic digital filter initialization (DFI)-based procedure for assimilating radar reflectivity data within the hourly updated Rapid Update Cycle (RUC) was developed in 2007 and is now in final testing at NCEP, with a planned operation implementation in Fall of 2008. This will mark the first operational use of WSR-88D mosaic reflectivity data...

Hourly convective probability forecasts and experimental high-resolution predictions based on the radar reflectivity assimilating RUC model

Despite a significant research effort over the past two decades, the prediction of convective storms and the associated warm season precipitation prediction problem remains a formidable modeling and assimilation challenge. The large forecast uncertainty associated with convective situations, even at very short lead times, coupled with the severi...
