l. Visualize Results

In this section, the results of the job just run will be visualised using NCL.

  1. If not still connected, connect to the Head node via DCV, following instructions from part h. Connect to the Cluster

  2. Install NCL using:

sudo yum install -y ncl
  1. Some of the default arguments for NCL need to be filled. Now that it has been installed, this can be done by sourcing the .bashrc file:
source ~/.bashrc

We will also set our default NCL X11 window size to be 1000x1000.

cat << EOF > $HOME/.hluresfile
*windowWorkstationClass*wkWidth  : 1000
*windowWorkstationClass*wkHeight : 1000
EOF
  1. In a terminal navigate to the WRF run directory.
cd /shared/conus_12km
  1. The provided ncl_scripts/surface.ncl script will generate two plots of surface fields at valid time 2019-11-27 00:00. Use the space bar to advance to the next plot.
ncl ncl_scripts/surface.ncl

Surface temperature

Use the space bar to advance to the next plot.

Surface dew point

  1. Generate a vertical profile of relative humidity (%) and temperature (K).
ncl ncl_scripts/vert_crossSection.ncl

Surface temperature

Again, use the space bar to advance beyond the current plot.
