Data Assimilation Study for TC intensity

Project Description

HFIP and NOAA have identified the initialization of the HWRF operational forecast system as a key area in need of improvement. The DTC continued to work with a core group formed under the auspices of HFIP to improve the GSI-hybrid system performance for the HWRF application. The primary effort focused on setting up and testing the GSI-hybrid system for the high resolution inner-core moving nests.

Specific testing components are then set up based on the HFIP DA milestones and in consultation with the EMC and other development teams. The DTC AOP 2014 T&E activities related to the application of the GSI-hybrid system for the HWRF application mainly focused on diagnostics for the 2014 HWRF spin-down issue and investigating the current two-way GSI-hybrid capabilities.
