To alleviate these deficiencies, various newer higher resolution global reanalyses are utilized to extend the track, intensity, and structural historical best-track archive. The gridded reanalyses utilized to this end include ERA40, ERAI, CFSR, and MERRA, with all reanalyses used when possible to produce an ensemble of historical extended tracks. The full track archive is made available for community use.
Analyses of the extended track dataset include: 1) quantification of the continuity (or lack there of) in location, intensity, and structure at the transition point between best-track TC and gridded reanalysis TC; 2) quantification of the threat to higher latitude countries based upon these extended tracks, to complement the existing landfall threat at http://moe.met.fsu.edu/tcprob; 3) quantification of the variance among track, intensity, and structure based upon reanalyses intercomparison for the post-best-track extensions.
