Tropical Numerical Prediction

Abstract

Long Term Goals. Improvement of high resolution ensemble modeling of hurricanes. This modeling effort utilizes a hierarchy of models: a) a global model that provides lateral boundary conditions and the base state for a regional spectral model, b) a high resolution global model that provides physical initialization, ie. the initialization of the initial rain rate from an assimilation of the observed rainfall from satellite and SSM/I data sets, and c) a regional spectral model that provides a high resolution ensemble forecast. The ensemble forecast utilizes an EOF based perturbation generation strategy. Ensemble averaging based on several techniques are being used presently. This system is naturally designed for strategies of adaptive observations towards improving observations, assimilation and hurricane forecasts.
