Understanding the Impact of Outflow on Hurricane Intensification through Ensemble-Based Data Assimilation and Ensemble Simulation with Multiple Models

Abstract

Evolving outflow jets dynamical and thermo-dynamical structure and location during the hurricane life cycle are increasingly believed to have profound impacts on storm intensity and structure. To advance the understanding of the influence of the outflow layer on TC intensification, high resolution, accurate observations that sample the outflow layer are needed. Flying at high altitudes, the WB57 aircraft sponsored by ONRs TCI program released HDSS dropsondes that sampled all the way from the outflow layer to the ocean surface. The primary goal of this project is to understand the impact of outflow on hurricane intensification through ensemble-based data assimilation.
