2007: Simulation of recent multi-decadal increase of Atlantic hurricane activity using an 18-km regional model
A new 18-km-grid regional model successfully reproduces the observed multidecadal increase and interannual variations of Atlantic hurricane activity since 1980, using large-scale interior nudging toward the NCEP reanalysis. H urricane activity in the Atlantic basin increased markedly in the years 19...
