1-1PC-HYSPLIT WORKSHOP
Part 1: Meteorology
Example SimulationsExample Simulations
Presented on the following slides are several meteorological data display examples that you can run prior to viewing the next few sections of the workshop.
The first slide of each example will present the problem to be answered, the next few slides will show the GUI inputs, and the last slide will show the resulting map.
It is recommended to click on the Reset button of the main HYSPLIT menu before proceeding in order to clear out any old cases in the working directory.
Note: These runs were produced using HYSPLIT version 4.9 (released January 2010). Slight differences are possible with older/newer versions of the model.
1-2PC-HYSPLIT WORKSHOP
Example 1: MeteorologyExample 1: Meteorology
Explore the wind field near New Orleans, LA, for a future dispersion exercise.
Source Location: New Orleans, LA (30.05N, 90.03W)
Date/Time: February 18, 2009 beginning @1200 UTC
Meteorology: NAM 12 km SE US tile (hysplit.t12z.namsf.SEtilew)
Display: 1a) Show 10 meters wind vector maps every 3 hours beginning 1200 UTC February 18 (see next page for defaults).
1b) Hourly profile output at source location beginning @1200 UTC using the Polar coordinate system to show wind direction and speed. (This may take a few minutes to generate.)
Notes: The NAM dataset begins with February 17, 2009 @ 1200 UTC and has data every hour, which can bedetermined by running Check File.

Note that the winds are initially from the SSW, but then come from the WNW by 0600 UTC on February 19.
