Abstract:

The first purpose of this study is to elucidate the physical mechanisms underlying changes in hurricane structure and intensity, including rapid deepening and eye wall replacement cycles. Specifically, the role of cumulus convection and the atmospheric boundary layer in the evolution of outward-propagating Rossby wave disturbances and their interactions with a developing hurricane is being investigated. The second purpose of this study is to describe and understand how three-dimensional asymmetric interactions between a hurricane and its environment determine the hurricanes motion. Specific questions to be addressed include What atmospheric levels steer the storm What spatial scales
