UPDATE: Patch - V1.1d for hurricane tracking

Post by **Tim Vasquez** » Thu Sep 02, 2004 5:00 am

Because of the catastrophic potential of Hurricane Frances I have issued a patch (V1.1d) that fixes a bug found in the NHC hurricane tracking import routine. Basically the import would not read anything past line #50 of a bulletin as a safety guard. I have changed this to look for $$ or NNNN as an end-of-report header. The problem caused hurricane tracks to not plot out to their full forecast when a lot of text was contained in the bulletin.

Also I have added the scripting command HURRICANE which plots NHC tracks, and added output.wrq that may produce "warning file not found" errors on fresh installations.

Here is a sample of code that will plot the path of Frances. Schedule it for every hour and you'll always have a plot of the latest track.

Code: Select all

This is of course for Digital Atmosphere Workstation users only (V1.1c; if you don't have V1.1c then download it from that page before using the patch)). Professional Version users may install this patch but it will downgrade their installed version to Standard. It is best for Professional users to contact me via E-mail and I'll E-mail the Professional Version patch to you.

I apologize that I have not been participating in this forum regularly. I have had to break away from DA for awhile to work on a new book and take care of the 8-month old baby. However I have been answering all tech support questions that have come in via E-mail. If you don't get an answer in the forums, please E-mail me, though the forums are the best place to get a wide variety of help. I'll try to get back into the forums more often soon.
