Max wind gust calculation

Post by pattim » Wed May 06, 2020 8:34 pm

WRF itself doesn't calculate max wind gust. Although there is an option in uems to post-process (auxhist* files) calculate max gust speed, upon inspection the result doesn't seem any different from the output values contained in the wrfout**.nc files.

Code: Select all

 (MAX_GUST_ON_SPEC_HGT_LVL_ABOVE_GRND_10m)                  SCAL=(4.0) !  Period Maximum 10m Wind Speed (Gust) (m s-1) FNUM=(1004)
 L=(10000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000)
I notice some gust algorithms for various high-orography areas:

Does anyone know if these or similar are contained in uems?

Thank You Very Much!!
