The 1/12 degree Global HYCOM Real-Time Nowcast/Forecast System

Abstract

1/12-deg Global HYCOM Configuration: Horizontal grid: 1/12-deg equatorial resolution - 4500 x 3298 grid points, ~6.5 km spacing on average, ~3.5 km at pole * Mercator 79-deg S to 47-deg N, then Arctic dipole patch * Vertical coordinate surfaces: 32 for o2* * KPP mixed layer model * Thermodynamic (energy loan) sea-ice model * Surface forcing FNMOC NOGAPS 0.5-deg wind stress, wind speed, thermal forcing, and NOGAPS 1.0-deg precipitation * Monthly river run (986 rivers) * Initialize from January climatology (GDEM3) T and S, then SSS relaxation from PHC 3.0 - No subsurface relaxation to climatology.
