They will be already, since the OT weather ia plugged into JSBSim directly through FGWinds.

Outerra handles the wind globally right now, so it will effect all locations the same, but using langdon's technique or another implementation through the Outerra API will are able to control the wind locally for each JSBSim instance in the world. There should also in the future be localised weather in Outerra.

Langdon, where are we going to get a peek at what you've been working on on?  :D

From JSBSim Class List:

I'm not sure this is the right place to post.
Maybe there's a PLUGINS category somewhere?

Anyway feel  free to do as you please with this:

http://www.siliconroad.com.au/ot/siliconsky_01_plugin.zip

I actually started to upload this and thought to myself, I should probably check it with an aircraft...Uhoh! Problem.. It turns out that position info isn't sent to the IGC plugin when you're in a vehicle, so a couple more hours and 1 hack later and here I go again.

As it stands the plugin will work in what I call superman mode, ie. when you are not in a vehicle. To have it work when you're in a vehicle I need to add a few lines of code to the vehicle script and change a setting in the plugin config (.cfg) file.

change_with_vehicle=0   <-Superman mode
change_with_vehicle=1   <-works when you're in a specially modified vehicle.

There are ways to make this more automatic but for a first 'proof of concept' type version, this'll have to do.
If you do feel like adjusting the config file then you can download a modified Mig-29 here:

http://www.siliconroad.com.au/ot/mig29.siliconsky.zip

Any suggestions, requests, criticisms  are most welcome. Some of the settings just  don't seem correct to me. Example. FEW - few clouds should be around 15 percent coverage but in Outerra scattered is more like 6 percent, so things like that need some tweaking.

I suck badly at anything graphical so if someone has an idea for an interface or layout just draw me a picture. The next version of this should come with a multiplayer option as well. I've now got my second machine back up and running so I should have something cobbled together in the next few days.

There's a readme.txt but here it is for those who don't wish to download.

CLOUD COVERAGE...
=================
CAVOK = 0 percent
CLR = 0 percent
SKC = 0 percent
FEW = 15 percent
SCT = 40 percent
BKN = 75
OVC = 100 percent
OVX = 100 percent ???

CLOUD BASE is first indicated BASE
CLOUD HEIGHT is 1000ft or highest base minus lowest base

WIND....
=============
Wind speed is knots. Can be adjusted by multiplier in cfg. Trees/grass don't seem to move enough at low speeds. Aircraft are affected correctly.
IE. landing a cessna in a 9 kt headwind with a 10x multiplier turns it into a helo.
Wind currently has no gusting or variable direction component. No turbulence.
Soft interpolation essentially means no shear either.

PRECIP....
===========
Rain is precip_in/30 to give a more realistic look.
No Snow yet.

FOG...
==========
No fog yet.


At this point only using METAR info. Large weather stations ie. Large airports. Download is approx (1Mb) on startup.
Plan to incorporate TAF info as well.

Winds aloft data is available. Approx 40Mb.  Need to find a way to decrease the download size.

CONFIG FILE...
==============
wind_multiplier=1  // Increase wind by a factor of
weather_interpolation_time=5000  //Time in milliseconds it takes for the weather to transition from one state to the next.
change_with_vehicle=0  // 0=weather changes as user moves around in 'superman' mode.  1=weather changes as user moves around in specially adapted aircraft.

FUTURE...
=========
Obviously a better interface (:
Plan to have save/load weather/enviroment profiles.
Want to try a 'weather architect' similar to REX.


NOTES....
===========
If you have the metar.cache.csv open in say Excel when Outerra starts, the download will fail.
Outerra  throws an error on exit. This is a known bug. Something to do with the SINGLETON cleanup.



One last thing. These are dll's. So it's all 'at your own risk'. I run virus checkers but nothings ever 100% safe.

JSBsim comes with it's own turbulence code... all we need is to turn it on.

This is the difference between 'weather' and 'atmospheric conditions'... so if the weather code says 'thunderstorm' JSBsim should be able to provide the turbulence to match this condition.

Anyway I'm asking the guys at JSBsim how to turn it on....

The thing we don't have is thermals and ridge lift which are the staple diet of gliders.

Just a note, the entire folder insides Langdon's zip has to be copied inside the plugin folder, in your Outerra install directory (C:\Program Files (x86)\Outerra\Anteworld\plugins for example) :)

Edit: had time to test it and wow... Having dynamic weather, even in this early state changes a lot of things. Really promising, great project! Only bug so far is OT crashing when exiting the engine, but you already know that.

Quick note...

In my routine that converts ECEF to LatLon I typed an 8 instead of a 3 into my flattening constant.

What this means is that the Lat/Lons are being computed wrongly.
It'll be correct in the next update.
