Something I haven't picked up, but was brought to my attention by my fellow forecasters is the direction of the wind barbs.
I know you guys in the Northern Hemisphere would not have picked this up, since it is correct Northern Hemispheric barbs, but in the Southern Hemisphere the barb should be the other way around.
I hope this reaches Jeff in time to consider fixing it in his next update.
Thanks for the heads-up. I'll look into it. Just to make sure we are clear, for an east-to-west wind, all barb flags should be pointing tward the south, reguardless of hemisphere?
I found the issue with the wind barbs & the fix is no problem. The only thing is I found the bug back in the origional PCGRIDDS code. Has this problem been there all along? I guess the program should follow the WMO standard but I'm not sure what that is. As far as I'm concerned, it can go either way but I think it needs to be right. I just find it odd it has been this way for this long. All of my systems are now Win 2k so I can't run DOS PCGRIDDS to check on it. If there are other international/southern hemisphere users who wish to contribute on the issue, I'm all ears.
Yes Jeff, the barbs should point polewards if the flow is zonal. In the DOS version of PCGridds the barbs is right, that is why some of our forecasters notice it. I myself is not too concern about it, I feel if the barb at least indicate the right speed it's okay, but some people find it strange.
I know that we are probably the only people who would've picked up this problem, since PCGridds is mainly used in the Northern Hemisphere where this problem wouldn't be noticed.
Please check this out in DOS PCGRIDDS; If you have a WAFS or other file which covers the southern hemisphere, do the command ALAT. Please see if the latitude numbers are displayed positive or negative value. This could be the key to the issue...I have a theory.
