Happy New Year Everybody!
I’ve just compiled and made an installer for what I hope is WXSIM Version 2025 Build 1.0, but of course I’d like people to try it out before I make it official (or catch and correct any bugs). You can get the upgrade at
www.wxsim.com/wxsim2025upgbeta.exe
if anything goes wrong, you can restore the previous version (2024 Build 1.1) using this
I’ll list the changes below.
Thanks!
Tom
CHANGES SINCE 2024 BUILD 1.1:
The ‘Anthropegenic and Solar Forcings’ algorithms were changed slightly in response
to updated research - in part done in support of and resulting from output of my
Clima-Sim program, but also from further observations over time and more extensive
study of the rate of warming (whatever the causes) in different geographic regions.
The biggest change was a considerable reduction in the effect of the solar (11-year
sunspot) cycle. I had previously used direct calculations of rather immediate
effects of changes in the solar constant, which I’d considered could cause an
amplitude (either side of the mean) of almost 0.09 C. Now, both my modeling in
Clima-Sim and my very careful study of NASA’s GISTEMP data shows this amplitude to
be almost undetectable (I think this is largely a result of “thermal inertia, so to
speak), so I’ve reduced this amplitude to about 0.01 C. My recalibration of the
warming (which is a somewhat complex pattern, based on historical trends) results
in a slightly smaller warming that I’d had before for some Northern latitudes, but
slightly more than before over Southern Hemipshere land masses. For future warming,
I’ve adopted a trend close to the “RCP4.5” scenario, widely regarded as a mid-range
and very plausible eissions and warming future.
To allow a finer look at the warming rate, I’ve changed the temperature text box
display to two decimal places instead of the previous one (so now, hundredths of a
degree). This is displayed when you change the date in the text box at top left,
and reflects the “normal” mean temperature for that date. Note that customizations
are based on 1981-2010 climatology, with this factor “correcting” for that.
A header, “UTC Date/Time” has been added for the last column in latest.csv (or saved
versions of that).
The “Import Data” and “Import Local Data” options under the “Import” menu item
on the Data Entry Form now have addiotal wording: “(Access with Auto Run OFF)”. It
has not been obvious previously that Auto Run needs to be temporarily deactivated
(under Start/Auto Run and Other Settings) in order to made changes on those forms.
With Auto Run ON, the forms disappear before manual changes can be made.
The help files have been modified slightly, with additional wording and information
about the ‘Wind gust controls’ (under Preferences/Settings/Tab 1). This issue can
be confusing, so I recommend reading the blue text help there.
wret.exe was modified to correct a problem that occurred with the (relatively new)
Cumulus MX file name format (now numerical months instead of previous first three
letter os the month name). The problems had been that the previous version of wret.exe
would (with this file type only), revert to the first of two months when the analysis
went to the next month.
