Session
12 Hurricane Analysis and Forecast System [HAFS]: Research Development and Operational Implementation
Description:
This session is an open invitation for all speakers to present their work related to Hurricane Forecast Improvement Program strategic goals: improving hurricane research, observations, UFS Hurricane modeling, forecasting, and communicating hurricane risks to all audiences. The Hurricane Analysis and Forecasting System (HAFS) is NOAA’s next-generation, multi-scale numerical model and data assimilation package, which will provide operational analysis and forecast out to seven days. HAFS will provide reliable and skillful guidance on Tropical Cyclone (TC) track and intensity (including RI), storm size, genesis, storm surge, rainfall, and tornadoes associated with TCs. The initial operational capacity of HAFS was approved by National Weather Service (NWS) for operational implementation for the 2023 hurricane season. HAFS comprises five major components: (1) storm-following telescopic moving nests, (2) high-resolution physics configured for TC application, (3) multi-scale Data Assimilation (DA) with vortex initialization, (4) full three-way atmosphere-ocean-wave coupling framework,and (5) intensive hurricane observational platforms to support the multi-scale DA system, the physics packages evaluation and improvement, and forecast verifications.
