Estimations of Diabatic Heating for an Explosively-Developing Maritime Cyclone.

Abstract

This thesis evaluates the Navy Operational Global Atmospheric Prediction System (NOGAPS) boundary layer and cloud parameterizations for a case of explosive cyclogenesis in the western North Pacific Ocean. Storm-region diabatic heating estimates are obtained from the application of quasi-Lagrangian diagnostics to a thermodynamic energy budget calculation, and from the NOGAPS diagnoses. The model-diagnosed sensible heating appears to be correctly positioned, while the diagnoses of convective, large-scale and open-cell cumulus condensation heating produce cloud features which generally reflect the distribution of the clouds in the satellite imagery. NOGAPS provides a better estimate of the diabatic heating over the open ocean than does the thermodynamic energy budget calculation. The contribution of diabatic heating in this case study is determined to be as significant as that of thermal advection. This diabatic energy input is an order of magnetic greater than that determined from studies of continental cyclogenesis.
