Hiya.
I chose "other". I have used weather off and on over my 3+ decades of gaming. Recently (last half year or so), I've been using it every time I DM. I bought a program for weather waaaay back when called "Weather Master", from MilieuSim. It was online-only activation, and I emailed him about a possible other option for registration...no go...but "if MilieuSim ever changes servers or goes out of business, we'll release a personalized patch for each person". Of course, they closed doors and *didn't* relase a patch for registered users. So, we users, had to find...er..."creative ways around" reigstration.
Anyway...Weather Master is an awesome program. You can use it to create your own worlds...how many moons, size, base temperature and a bunch of other scientific terms and ratings I have no idea about. One major thing I use is it's daily "Log"; you can type in notes and whatnot. I use it to keep track of particular events going on with NPC plans/goals, holiday's, etc. You can print out a day-by-day list of sun rise, sun set, moon phases, high/low temp, "block-hour" weather changes (e.g., "7am...", "12 noon...", "8pm..."), etc. (in metric or imperial).
So, yeah. WeatherMaster allows me to keep track of day-to-day weather and campaign/story lines all in one place...and allows me to print to paper or .xml (which I can then convert to PDF to use on my TabletPC).
