Impact of Assimilating Multi-Function Phased Array Radar Observations on Storm-Scale Ensemble Forecasts of Severe Convective Storms
National Severe Storms Laboratory
||Norman, OK 73072
With the advent of Multi-function Phased Array Radar (MPAR) technology, it is now possible to scan the same weather phenomenon using both adaptive scanning and faster volume update capabilities of the system. Studies conducted using both Observing System Simulation Experiments (OSSE) and real data experiments show that faster scanning rate of MPAR may yield improvements in storm-scale forecasts from assimilating over a shorter assimilation window. The proposed research seeks to extend the initial findings and examine how to best assimilate the adaptive high temporal frequency MPAR observation into numerical weather prediction model with the goal to increase severe weather warning lead times (Warn-on-Forecast).
