Introduction |
Note: This script determines the center via wind field data only. So it might be wrong when the the circulation changed. (i.e. TC interacts with terrain or other weather systems.) Suitable for TCs before making landfall.
|
Usage |
Please define the following variables in the script first:
- Operation height (Variable: height , default value is 850hPa)
- Range for consistency check (Variable: range, default value is 0.6 degrees in lon./lat.)
- Range for finding minimum wind speed after the location of the maximum relative vorticity was found.(Variable: Increment, default value is 0.6 degrees in lon./lat.)
- Split the searching range in how many times? (Variable: TotalSteps, default value is 10)
Open your .ctl file after startup GrADS, then you can run this script. The following options will be asked:
- Run for all time steps in this .ctl?
- Perform consistency check or not?
- If YES, you will be asked if you want to specify the center for the first time step or not. If YES, you have to enter the lon./lat. data.
- Verbose mode?
- Close the file after job done? (File Number 1)
A red cross will be placed on the location of the maximum relative vorticity; a cyclone symbol at the location of the minimum wind speed.
