WRF Israel 4km - Snow Forecast & Simulated Radar Reflectivity 1 year 4 months ago #935
|
Hi,
I noticed that there is a problem in snow depth map for (Israel_ 4km_ WRF model) grib file. It indicates that there is a snow in some areas for tomorrow (Monday 26th Dec) but in actual there is no prediction for snowfall. Are there any issues regarding the miss estimation of freezing altitude or related to the micro-physics scheme? Also, over the last few months I have noticed that the simulated radar reflectivity (dBZ) prediction is no longer as accurate as it once was. Many times large values of dBZ are predicted (hail storms and thunderstorms) and in reality there is nothing. What is the issue regarding this? Is this due to the use of different radiation and the microphysics schemes? Here is some of the screenshots of the last run 00Z25DEC2022 showing these issues:
