Measuring a tree’s bend and local wind speed tests whether deformation tracks wind force.

Evidence

These approximations suggest a scientific project for the reader: take a wind-bent tree, measure its angle, and then determine with a good wind gauge the actual force of the wind striking this tree on the average over a year’s time. — Vinson Brown, Reading the Woods, 172
