Hi Everybody,
To fix a couple of “bugs” that were reported recently, I’ve just made changes to both wxsim.exe and wret.exe. Both are now referred to as Version 2016 Build 1.1. The new executables are
These should be downloaded to simply replace the ones you already have. I have not yet put them in the upgrade installer (they’re kind of “betas” for the moment), so if any problems arise, you can go back to the previous versions by running
Here’s what was reported, and what I did:
(1) In WXSIM, there were sporadic reports of “No READY or GFS data found”. In some cases, at least, this was actually not “true”; data WERE found, but were judged to be “unbelievable”. Specifically, every now and then GFS chugs out a relative humidity lower than 1%. I did have a filter to reject anything that low or lower, but have now eased up on the restriction, so WXSIM will “beloeve” values as low as 0.01%. Frankly, that surprises me, but it is what it is! These very low RH’s seem to happen only in upper levels of the atmosphere, so they really won’t hurt the surface forecast, anyway.
(2) In wret.exe, a couple of people recently reported an error #9 (subscript out of range). I found this to be because these users had 10,000 or more forecasts archived! I had not considered that large of a number when dimensioning arrays (up to 9999), but in fact people running close to 20 forecasts a day for a year and half can indeed collect that many! That’s frankly too many for wret.exe/autolearn to use anyway, so the oldest forecasts (.wxf) should be placed in another folder for safekeeping. However, I don’t want users to ever have to see the error, so I’ve “pre-empted” it, by checking the numebr of forecasts before the error gets a chance to occur. Now a message box appears, instructing the user to get the number down under 10,000 by moving the older forecasts to another folder.
Please let me know how it goes!
Tom
