Getting Started from the Terminal Window
If Tcl/Tk has not been installed, then the model can be run from the terminal window from the ./hysplit4/working directory. Prior to the models first time use it may be necessary to copy ../bdyfiles/ASCDATA.CFG to the ./working directory.
[Command line trajectory example:]
(https://ready.arl.noaa.gov/hyreg/HYSPLIT_applehysp.php)
cp sample_traj CONTROL
../exec/hyts_std
../exec/trajplot tdump
open trajplot.ps
Command line concentration example:
cp sample_conc CONTROL
../exec/hycs_std
../exec/concplot cdump
open concplot.ps

PySPLIT: a Package for the Generation, Analysis, and Visualization of HYSPLIT Air Parcel Trajectories

Abstract
The National Oceanic and Atmospheric Administration (NOAA) Air Resources Laboratory's HYSPLIT (HYbrid Single Particle Lagrangian Transport) model Drax98, Drax97 uses a hybrid Langrangian and Eulerian calculation method to compute air parcel trajectories and particle dispersion and deposition simulations. Air parcels are hypothetical small volumes of air with uniform characteristics. The HYSPLIT model outputs air parcel paths projected forwards or backwards in time (trajectories) and is used in a variety of scientific contexts. Here we present the first package in the mainstream scientific Python ecosystem designed to facilitate HYSPLIT trajectory analysis workflow by providing an intuitive API for generating, inspecting, and plotting trajectory paths and data.

You may calculate vorticity firstly (http://www.meteothink.org/examples/me ... hdivg.html) and then extract the vorticity data along the trajectory (http://www.meteothink.org/examples/me ... _data.html).

Meteorology Output Along the Trajectory
Sets the option to write the value of certain meteorological variables along the trajectory to the trajectory
output file. The marker variables are set to (1) to turn on the option. Multiple variables may be selected
for simultaneous output but only one variable may be plotted. If multiple variables are selected in
conjunction with the trajectory display option, then only the last variable output will be shown in the
graphic. The variable output order is fixed in the program and cannot be changed.
● TM_PRES (0) - diagnostic marker variables to output atmospheric pressure (1) along the
trajectory
● TM_TPOT (0) - potential temperature (1) in degrees Kelvin
● TM_TAMB (0) - ambient temperature (1) in degrees Kelvin
● TM_RAIN (0) - rainfall (1) in mm per hour
● TM_MIXD (0) - mixed layer depth (1) in meters.
● TM_RELH (0) - relative humidity (1) in percent.
● TM_DSWF (0) - downward solar radiation flux (1) in watts.
● TM_TERR (0) - terrain height (1) in meters required for the trajectory plot to show underlying
terrain.
