Estimating Winds from Synthetic Aperture Radar under Typhoon Conditions

Abstract

The Impacts of Typhoons on the Ocean in the Pacific (ITOP) program is a multi-national field campaign that aims to study the ocean response to typhoons in the western Pacific Ocean. The main goals are to understand the formation and dissipation of cold wakes and how ocean eddies affect typhoons. CMRE s activities within ITOP are related to SAR wind retrieval and therefore will be helping to better understand air-sea fluxes under extreme wind speeds and improve the knowledge and forecast of surface wave field under typhoons as well as the Typhoon forecasting. CMRE (former NATO Undersea Research Center) is part of the ITOP SAR Team working on extracting wind and wave information from synthetic aperture radar (SAR) data. Their major objectives are the development and implementation of a SAR Typhoon Processing System (SARTyPS) for near real time processing of SAR data with respect to estimating wind and sea state under tropical cyclone conditions. It is anticipated to incorporate the SAR-retrieved information into numerical models in particular with respect to tropical cyclone forecasting. The main objectives for CMRE are the development of algorithms that are capable of extracting wind information from SAR images in near real time and fully automated. The SAR activity within ITOP is a close cooperation with the Center for Southeastern Tropical Advanced Remote Sensing (CSTARS) of the University of Miami, General Dynamics Advanced Information Systems (GDAIS) and the Applied Physics Laboratory (APL) of the University of Washington.
