U-shaped branching is considered the most favorable arrangement for withstanding high winds due to its structural stability. This branching pattern allows for a more balanced distribution of weight throughout the tree. The wide angle at which the branches grow helps them to flex and sway with the wind rather than breaking off.

In contrast, horizontal branching tends to catch more wind force, which can create leverage against the trunk of the tree, increasing the risk of limb failure. V-shaped branching, while it can allow for some wind movement, typically creates a weaker attachment point at the base of the branches, making them more susceptible to breakage. Overhanging branches can be particularly problematic as they often extend away from the trunk and can become top-heavy, leading to increased strain during wind events.

The unique design of U-shaped branches provides an effective method for trees to manage wind forces, enhancing their overall resilience in storm conditions.
