【正文】 pressure levels), skewT, and vertical crosssections. They currently plot model output variables plus a few diagnostic variables, such as SLP, dew point temperature, and RH. Can work with multiple input files and subdomains NCL for WRF Model Data Advantage: NCL reads WRF data directly Can make simple plots quickly Easy to make difference plots Disadvantage: Initial learning may be slow Array putation may be slow unless using Fortran Downloading From web site: tar file: After untar, one finds directory WRF_NCL/README_FIRST README_NCL eh/ em/ WRF_NCL/em/ directory make_ncl_fortran Scripts to build fortran shared library Created by fortran build NCL functions and procedures used by the plotting scripts Plotting scripts Contains functions and procedures that are used by all ncl plotting scripts: maps contour and colorfilled plots vectors To include it in a ncl script: load “” Functions for making skewT plots Load near the top of the ncl plotting script This is where a user may choose to add new variables for plotting Can be used to obtain native model output variables, or diagnose new variables Make Fortran calls to routines in Use existing examples inside the file as templates for adding new variables Contains Fortran routines for diagnostic calculations Fortran routines are stubbed with ?NCLFORTSTART? and ?NCLEND?. .
