P21 Central U.S. WRF
composite radar verification using MODE-Time Domain
Flemke, Jason, University of Saskatchewan
A 4-km convection-allowing Weather Research and
Forecasting (WRF) model was ran for the contiguous United States from October
2000 to September 2013 (Liu et al. 2016). Downscaling to a higher resolution
of 4-km permits the model to simulate deep convection without
parameterization. Here, a verification of the model's simulated composite
radar reflectivity in comparison to the Weather Surveillance Radar-1988 Dopplers (WSR-88Ds) national mosaic is performed using
the Method for Object-Based Diagnostic Evaluation (MODE) with the included
Time Domain (MODE-TD). The comparison focuses on the Central Plains of the
U.S. for convective systems from March through August. |
