Another thing I'd like to point out is the learning value of actually taking the time to go through the whole (few minutes' worth) process of running WXSIM 'manually'.  I think carefully looking at the data, and how WXSIM uses it (and by running different scenarios with slight variations - or just playing around with 'pretend' weather conditions in other seasons, even some of the other sample locations), can make the user a better forecaster.

Tom,

I recently installed WxSim and WxsiMate and couldn't find a tutorial.  There are so many choices and I find it daunting.  Perhaps you have a "WxSim for Dummies" type walkthru that would help me learn?  Something that says start with these settings and see what you get, then change "this" and see how "that" changes.  I don't know all the lingo and abbreviations and what I should be expecting or looking at specifically.

Anyways, good to hear your working on the forecast automated option.

NorCal Dan,

When you installed the application it should of put a manual.doc file that opens up in word in the wxsim directory.  In there you would then have some scenarios to run through with all the different options that WXSim has. I also got Tom to add a glossary of terms in the manual as well with some basic terms which helped me a lot.

In the manual you will have two main topics:
III. Example Scenarios 5 - are the scenarios
XIV. Glossary of Terms 51 - is the glossary of terms.

that you can goto and learn about WXSim. Hope this helps! :-)

Thanks for that...I will take another look at the manual.  I read thru it once before but found it hard to understand all the terms, abbreviations, etc.

You ain't the only one who got totally lost with all the functionality of wxsim.

I've taken a stab in the dark and registered it, as I feel it a waste of time fiddling around with Atlanta all the time, when I'm primarily interested in something on the other side of the planet. :)

I "think" I have been importing my WD data and not Atlanta, but I can't be sure  #-o

I used Wxismate to import my log file, but it still says Atlanta across the top of the window.  It's suppose to be a fully functional program so I assume you can get a forecast for an area besides Atlanta even though thats what is displayed on the box.  Just finishing up some loose ends here and then I am going to take it for another spin, at least until I get disgusted with it again  :D

Maybe if I keep messing around with it something will click... #-o

The unregistered version of WxSimMate will only download data for Atlanta.

Hi All,

I registered WXSIM and WXSIMATE today and I have been working with Tom to get my software customized. I should be up and running in a few days. I will let you know how its going once I learn how to operate the model.

Hmmm, sure is a lot of clicking and altering in those examples.  I had hoped it would read my log files and handle all the details...It seems to require a lot of hands-on to make it produce an output.

Atlanta...no wonder my attempts at producing a local forecast seemed out of whack...bummer...

Hi All,

To answer a question which seems to have come up, WXSIMATE WILL read your local data from WD, even if it's not registered.  What it WON'T do until you register it, is to cull data for your specific site.  It can't, because to do that it would need all your site data, which is what I develop in the process of customizing it for you.

I think one source of confusion is simply that it's hard to realize at first what the program is.  It's a 'local interactive atmospheric model' - not that there are any others.  It's not intended as an auxiliary tool for WD, as I didn't even know about WD till a couple of years ago, and over 20 years into the development of WXSIM.  The tie in with WD is nice and convenient, but is actually a rather small part of using WXSIM.

Those tutorials in the manual were in response to requests for users, and many people have found them quite helpful.  It does take a lot of patience to work through them, but I think learning the program is quite worthwhile.

Something that only a few users realize at first is the value (and fun, really) of using it in a 'play' mode.  Even with the demo, you can pick one of the four sample sites, or enter latitude, longitude, and elevation, etc. data for anywhere in the world, and run all kinds of experiments.  You can make cold fronts come through in Sydney in July or watch the sea breeze effect shift the wind there during the day in January, put snow on the ground in Atlanta in July and see how long it takes to melt, play with surface and upper air temperatures to see under what conditions various types of freezing or frozen precipitation occur, compare windy clear days to calm clear days - or to cloudy days, to see how that affects the daily temperature range.  Of course, you can also make a serious, accurate forecast with all kinds of detailed information you'd rarely find elsewhere, which for most people is the main point.  I just think you'll get a much better feel for it if you play around with it and enjoy it, instead of trying to get all the features working at first.  It can be run in a very simple mode.

I think it's very instructive to read the background of the program, both at www.wxsim.com and in the manual.  Also, I recommend taking a look at the cty.fdt file (it's plain text), to see what all goes into customizing it.  I develop data like that for each site I do.

Oh, be sure to click on any blue word in the program which you don't understand.  Instant help on that exact topic will pop up.

Hope that helps!

Tom

After playing with WxSim for the past few days I believe I finally understand.  I think you have a great product and, in the right hands (not mine obviously),  have no doubts it will produce accurate data.  Good luck with your project.

Hi All,
I know it's beginners luck, but yesterday I ran my first forecast and it projected todays high temp. to be 31.8 --- it was off the actual high temp was 31.6.

This is a very complicated program but I'm an old retired IS executive and I will figure it out. It has a zillion things you can tweak so it should be a fun challenge.

I would welcome and advise anyone has on running the program.

Thanks John
