The default wind is constant (given value is 0.02). Wind turbines mods I studied KS Power and Wind turbines V16 both makes the wind vary over time but maybe I am wrong. Have you tried Mo'Weather ? This is all for the community to make mods that use the wind speed, change it when needed, decide what the 0.02 unit is and make the whole thing compatible. So that I am glad you asked and think about it. There is another signal I could have added which is the wind direction variation but it is not used by mods at all and its value is always 0.0001 or -0.0001 or something like that.
My real question is do you need settings to hide undesired signals ?
