""" MODE: Multivariate ================== model_applications/short_range/MODEMultivar_fcstHRRR_obsMRMS_HRRRanl.conf """ ############################################################################## # .. contents:: # :depth: 1 # :local: # :backlinks: none ############################################################################## # Scientific Objective # -------------------- # # This use case demonstrates how to run Multivariate MODE to identify complex # objects from two or more fields defined by a logical expression. This use # case identifies blizzard-like objects defined by the intersection of : 1) the # presence of snow precipitation type, 2) 10-m winds > 20 mph, and 3) visibility # < 1/2 mile. The use of multivariate MODE is well-suited to assess the structure and # placement of complex high-impact events such as blizzard conditions and heavy # snow bands. Output from this use-case consists of the MODE ASCII, NetCDF, and # PostScript files for the MODE forecast and observation super objects. # # In this case, MODE super object intensity statistics were ouput for both 10-m # wind and visibility. Using the the MODE_MULTIVAR_INTENSITY_FLAG, the user can # control for which variables super object intensity statistics will be output. # If all are set to False, then no intensity information will be output and only # statistics relative to the super-object geometry will be available. In the case # no requested intesities, the parameters MODE_FCST/OBS_MULTIVAR_NAME and/or # MODE_FCST/OBS_MULTIVAR_LEVEL may be used as identifiers for the super-object. ############################################################################## # Version Added # ------------- # # METplus version 5.1 ############################################################################## # Datasets # -------- # # **Forecast dataset:** 1-hour HRRR in grib2 # # **Observation dataset:** MRMS and HRRR analysis in grib2 # # The forecast and observation fields are only a subset of the full domain in # order for a faster run-time of Multivariate MODE.
