• In this project we endeavor to create a real-time and fully automated surface wind analysis system at NHC by combining accepted operational wind reduction procedures and a comparably simple variational data analysis methodology (Knaff et al. 2011). Specifically, this project will make use of the Franklin et al (2003) flight-level to surface wind reduction findings along with current operational procedures and the automated analysis and quality control (QC) procedures used in the Multi-platform tropical cyclone surface wind analyses (MTCSWA; Knaff et al. 2011). The aircraft reconnaissance wind data (flight-level and SFMR), and the MTCSWA satellite-based MTCSWA will be used. The MTCSWA will serve as a first guess field with very low weighting and the aircraft-based data will be composited over a finite period of time and analyzed. The analysis will be performed on a polar grid at the surface level. The proposed wind analysis will run at NHC and make use of the local data stream and JHT servers. The resulting two-dimensional wind analysis will produce 1-min sustained winds valid for 10 meter (m) marine exposure with sufficient resolution to properly capture the radii of maximum winds. The polar grid resolution and domain size will be consistent with the resolution of the aircraft reconnaissance data and the needs of the forecasters.
