Understanding and Predicting the Impact of Outflow on Tropical Cyclone Intensification and Structure

Abstract

Funds are provided to conduct collaborative research between the University of Miami (UM), the Naval Research Laboratory, Monterey (""NRL) and CIMSS / University of Wisconsin, as part of the ONR Departmental Research Initiative (DRI) on Tropical Cyclone Intensity (T"CI). The goal is to increase the understanding of the dynamics of the upper-level outflow of tropical cyclones (TCs) and its connection to the larger-scale environment. The PI will investigate the following 3 topics for TCs sampled during the TCI field campaigns:" 1) He will conduct ensemble-based sensitivity and diagnostic tests, particularly focusing on outflow , 2) He will evaluate satellit""e-based Atmospheric Motion Vectors (AMVs) using dropwindsonde data collected during the 2015 TCI field campaign, and 3) He will eval"uate and diagnose the impact of assimilating special TCI data in the Navy~s COAMPS-TC modeling framework. The scientific results and conclusions on the sensitivity to outflow are expected to lead to enhanced guidance on how data in the outflow region influence nu"merical analyses and predictions of TCs, and how ensemble systems can be improved. Another expected result is the developemnt of an" array of software tools for rapid diagnostics and evaluation in the Navy~s NWP systems.
