Changeable weather

[daviessm]

Winds could change direction forcing controllers to route planes to a different runway. High crosswinds could mean (some) planes could not land.

Poor visibility could result in VFR flights being unable to land.

@daviessm: variable wind direction would be amazing. diverting a plane that is not able to land due to excessive CW to another airport should add points if ordered in a timely manner (e.g. prior to hitting localizer). rain could increase landing time/extend landing distance forcing adaptive taxiing practices. thunderstorms could drift through radar necessitating diverting aircraft to avoid weather.

Piggybacking on this one (just the wind part), I had the following to say (moved from closed issue #325):

---

It would add some realism if the wind could vary a bit. Not in the sense of necessitating a runway change necessarily, just that it has shifts and swells of direction and speed. I'm not sure how this is best implemented... what about based on a few levels of Math.random() values, like this:

• Net change from 0h0m->1h0m: [(Math.random() = 0.8513) x 2 - 1 = +0.7026] x 18kts = +13kt
• Net change from 0h0m->0h30m: [(Math.random() = 0.6912) x 2 - 1 = +0.3824] x 9kts = +3kt
• Net change from 0h0m->0h10m: [(Math.random() = 0.2860) x 2 - 1 = -0.4280] x 3kts = -1kt
• Wind @ (t): uhhhhhhhhhhhhhhhh????

This way, the changes would be random, but with a clear overarching trend. Somebody more well-versed may have a more intelligent solution, utilizing some of the functions from util.js that I still can't quite figure out what they do. If so, bring on the suggestions!

Picking up @harp71 comment from the other issue:

"wind": {
  "angle": [[250, 280], [70, 105]],
  "speed": [5, 20] 
},

would be a great solution I think. Now all there is left to write is a algorithm as suggested by @erikquinn, that can make this wind "come alive". Though I think that a very rare chance of completely off winds would be great and realistic as well.

Maybe this MATLAB Thread may help.

Also, as mentioned in #630, it might be interesting to have the option of updating the game with the actual live wind conditions.
