research summary
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
