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.
