Graphics: NCL - Example Scripts

Below are a few sample scripts that illustrate how to use NCL for plotting ARW WRF data:

Basic Plots

Basic Plot Setup
(This series of examples takes
users though same basic steps
in generating plotting scripts.
)
Get and plot a single field
Multiple input files
Plot all fields in a file

Basic Surface Plots  

Surface 1
Surface 3
Surface 2
Surface with multiple input files

Plots on Model Levels

Clouds
Levels from wrfout files
Levels from metgrid files

Plots on Interpolated
Levels

Height Levels
Pressure Levels

Plotting Precipitation 

Precipitation

Diagnostics  

CAPE
dBZ
PW
Vorticity
helicity
updraft_helicity

(More diagnostics are available,
shown are only some
newer/special diagnostics)

Cross-section Plots

Height - Through a Pivot Point
Height - Point A to Point B
Pressure
Limited Vertical Extent
For 2D fields
Smooth terrain

Precip Tendencies for a Moving Nest
Keeping a fixed background
for moving nest domain, and
plotting rainfall tendencies in
the overlapping regions
