... hurricane damage is developed. This approach uses empirical relationships between the large-scale environment and hurricane parameters that are known to cause damage (intensity, size and forward speed) to assess future hurricane damage. This approach projects a future decrease in mean tropical cyclone...

... in a simplified three-dimensional model for determining drift forces. That technique is extended further by inclusion of forward speed effects to allow determination of the additional linear wave drift damping term. Comparison of the theoretical results with model test data demonstrates the utility of the method...
