Abstract:

A 132 degree global ocean nowcastforecast system has been developed by the Naval Research Laboratory at the Stennis Space Center. It started running at the Naval Oceanographic Office in near real-time on 1 Nov. 2003 and has been running daily in real-time since I Mar. 2005. It became an operational system on 6 March 2006, replacing the existing 116 degree system which ceased operation on 12 March 2006. Both systems use the NRL Layered Ocean Model NLOM with assimilation of sea surface height from satellite altimeters and sea surface temperature from multi-channel satellite infrared radiometers. Real-time and archived results are available online at httpwww.ocean.nrlssc.navy.milglobalnlom. The 132 degree system has improvements over the earlier system that can be grouped into two categories 1 better resolution and representation of dynamical processes and 2 design modifications. The design modifications are the result of accrued knowledge since the development of the earlier 116 degree system. The improved horizontal resolution of the 132 degree system has significant dynamical benefits which increase the ability of the model to accurately nowcast and skillfully forecast.
