By incorporating established laws of tree allometry — which explain the relationship of tree size parameters such as diameter and height — the team was able to mathematically explain why the trees in Klaus's path (like those seen above) gave way once the wind speeds reached 42 m / s.

This pattern could result from natural selection for specific allometries or from developmental constraints on patterns of differential growth. (science.sciencemag.org)
