  1. Improved Understanding and Diagnosis of Tropical Cyclone Structure and Structure Changes GOAL: Develop new tools that enhance the current capabilities to diagnose tropical cyclone (TC) structure and location using GOES-R advanced baseline imagery (ABI) and GOES lightning mapper (GLM) proxies. John Knaff (PI,StAR) and Chris Rozoff (PI,CIMSS) Jim Kossin (NCDC) and Chris Landsea (NHC) Presented by M. DeMaria (co-Investigator, StAR)

  2. Storm Structure Affects Impacts Hurricane Charley 2004 Hurricane Ike 2008 Small category 4 Large category 2

  3. Research Summary • Use multi-spectral satellite and lighting data to improve center and wind structure estimation • Quantify factors responsible for TC size variation, especially variations in moisture • Guide algorithm development with high resolution WRF simulations • Microphysics sensitivity • Compare synthetic and real imagery • Statistical-dynamical models for size forecasting
