ii DEDICATION This is dedicated to my husband Yujie Zhao and my son Eric Zhao, from whom I have had the most happiness. iii ACKNOWLEDGEMENTS I am heartily thankful to my committee members, Dr. Ruixin Yang, Dr. Daniel Babara,

The aim here is to examine the advances that have occurred in satellite-based remote sensing since the IWTC-V, and to break new ground in some areas. In this report we briefly summarize new satellite-based methods to estimate the intensity and structure of TCs. The report is broken down into two main areas: Applications from IR images, and microwave data. After some background in each area, the focus is on research algorithms and potential operational applications that have been developed since the last IWTC 4 years ago. 1.a.1 IR Applications Early applications of IR satellite images for TCs were for tracking (center fixing) and intensity following the Dvorak technique (Dvorak 1975; Dvorak 1984;Velden et al, 2006). Those type applications remain today as the primary and most important applications. Since the original Dvorak development work, results have likely improved due to improved enhancements, animations, better image navigation, higher spatial resolution, and more frequent temporal resolution. 1.a.2. Objective and Advanced Dvorak Technique (ODT, AODT, ADT) Important applications followed Dvorak (1984) with the improvement of the original Dvorak algorithm (Zehr, 1989) and the Objective Dvorak Technique (ODT) Velden et al 1998). The original goal of the
