This Garcia Method tool is an interactive Gempak/Unix script. It requires user input to place the cross-section and choose the isentropic surface. A full description of these scripts can be found on the Garcia Method Page.
Two versions of the script are available. The first version, runGarciaQuick, takes a cross-section location as input and runs the Garcia Method analysis for this cross-section. This version takes less time to run than the version which requires the user to manually place the cross-section, however it offers less versatility.
The second version, runGarciaFull, begins by
displaying two four-panel figures of negative Q-vector divergence to allow the user
to choose a cross-section. This insures that the cross-section, or "area of interest"
lies in a region of forcing for ascent during the entire 12-hour forecast period, as
assumed by the Garcia Method. This is also useful for determing the strength of the
forcing for modifications to the Garcia Method estimate. Once the user has placed the
cross-section, the script continues in the same manner as runGarciaQuick does.
