Thread: Wind metering at distance

Pengy they are called wind flags if you are on a budget, anything more complicated and I have no clue. However there is work being done using drones for the military and gear that can see the movement of dust particles in the air to build wind models I would imagine it will be a while before us mortals can afford this type of gear. In the USA you can use apps that take wind speed and direction and overlay it on your topography building a sort of 3D wind model showing how it moves around ground features.
