Overview

Sensitivity analysis shows cloud microphysical parameterizations affect data assimilation and hurricane intensity forecasts.

Key Points

  • All-sky infrared radiance assimilation improved the forecast accuracy of Hurricane Harvey's intensity and track, indicating forecasting potential.
  • Sensitivity forecasts revealed that intensity errors were largely influenced by uncertainties in initial conditions related to microphysics schemes.
  • Different microphysical parametrization schemes led to significant variations in the dynamic and thermodynamic structures of Hurricane Harvey.
  • The choice of microphysics schemes during free forecasts had a smaller impact on intensity forecast errors of Hurricane Harvey's path.
