Vorticity Script

Post by svrwx »

For the more experienced people on the board, would it be possible to create a script which would plot absolute vorticity. For example, positive vorticity would be warm colors with negative cool colors.

Thanks

Vorticity Script

Post by Stefan Lichius »

Hi Matt,

try this one:
#Script: 500 hPa + Vorticity Analysis

ERASE
ANALYZE,HILO CONT EQUA=5520 COLOR=0:0:0 LINE=3 CONT CINT=60 COLOR=80:80:140 LINE=2 SMTH HGHT H500
ANALYZE,CONT CINT=2 COLOR=200:20:20 DOTS SMLC=1:100000 STOR=1 AVRT WIND H500
ANALYZE,MAXD COLOR=255:0:0
ANALYZE,MIND COLOR=0:128:255

Best regards,
Stefan

Pretty much the same as Stefan already posted, but if you wanted to add this to the digatmos.MNU (to run it from the menu) file this should work OK:

MXMN CONT EQUA=0 COLOR=0:0:0 LINE=2 CONT GRTN=0 CINT=2 COLOR=200:0:0 LINE=1 CONT LSTN=0 CINT=2 COLOR=0:0:200 LINE=1 SMLC=1:100000 STOR=1 AVRT WIND

This would work in a script as well be adding analyze, at the beginning and a desired height at the end... like Stefan added H500, or:

analyze, MXMN CONT EQUA=0 COLOR=0:0:0 LINE=2 CONT GRTN=0 CINT=2 COLOR=200:0:0 LINE=1 CONT LSTN=0 CINT=2 COLOR=0:0:200 LINE=1 SMLC=1:100000 STOR=1 AVRT WIND H500

Pretty much the only difference is Stefan's script adds heights and sets the level; the menu entry I posted doesn't do either, it only analyzes abolute vorticity and colorizes the isopleth; red for positive and blue for negative - it lets you adjust things using menus/drop downs. Just another way of doing the same thing:)
