There are currently two ways to get wind information. "wind" which returns an [x, y, z] array in meters per second speed. And, "windStr" which returns a 0-1 value. However, there is no "windSpeed" method. This would be relatively simple to add. Just something like this:

[code]
_windSpeed = sqrt(((wind select 0) ^ 2) + ((wind select 1) ^ 2) + ((wind select 2) ^ 2));
