This book examines scale interactions and energy transformations that occur during hurricane genesis. The organization of convection during hurricane genesis is first explored to establish which scales are evolving and to determine which wavenumbers constitute the hurricane scale. Next, complete energy budgets are examined in order to sort out energy flow during hurricane genesis. The framework of the study is based on the seminal papers by Barry Saltzman (1957, 1970) on atmospheric energetics in the wavenumber domain. The complete energy budget includes examination of the generation of available potential energy, conversion from available potential energy to eddy kinetic energy, the rate of change of kinetic energy due to nonlinear triad interactions, the rate of change of potential energy due to nonlinear triad interactions, zonal to waves flow of kinetic energy, and zonal to waves flow of potential energy.
