To achieve this, he integrates multi-platform (including aircraft and ground-based Doppler radars) observations with turbulence-resolving large-eddy simulations to improve the modeling of boundary-layer processes under hurricane conditions. His recently developed boundary layer scheme has been implemented into NOAA’s next-generation hurricane forecast model, Hurricane Analysis and Forecast System.
