Simulated tree from a functional–structural modelling suite. Using the freezing rain simulation tool IceTree, we have simulated a freezing rain event. Simulated ice accretion on branches of secondary branching order of the simulated tree showing covariation between SF (α = 10 cm, β = 10°) and ice accretion. Colour gradients (scale on the figure) show: (A) the simulated radial ice accretion (mm), and (B) SF.
