Forecast Models

A curated launcher for the models a marine forecaster actually reaches for. Each card links straight to the authoritative operational viewer — charts.ecmwf.int, NCEP MAG, the Navy, and the global wave and ocean models that drive routing decisions.

ECMWF Operational

European · Gold standard

Consistently the best-verifying global model in the 3–7 day range for most fields. Runs at 00Z and 12Z. The model every forecaster compares others against.

GFS Operational

NOAA · Workhorse

NCEP's global workhorse. Four runs daily (00, 06, 12, 18Z) out to 16 days, freely gridded, backbone of most downstream US forecast products. Looser than ECMWF in the mid-range — but catches some synoptic setups better.

NAVGEM

Navy · Marine-tuned

Navy Global Environmental Model. Tuned for marine boundary-layer physics and ocean-atmosphere coupling — the setup that matters most for cargo routing. Four runs a day.

GEFS

NOAA · 31-member ensemble

Global Ensemble Forecast System. 31 perturbed runs of GFS, four times a day. Where to look when deterministic guidance starts diverging — probability, spread, and the envelope a single run can't show you.

WAVEWATCH III

NCEP · Global wave model

NCEP's operational global wave model. Significant wave height, direction, period, partitioned by swell versus sea. The model ocean routers watch when planning crossings under moderate to heavy seas.

HYCOM

Navy · Global ocean circulation

Navy's Hybrid Coordinate Ocean Model. Sea surface temperature, currents, salinity at depth. The Gulf Stream, Kuroshio, and Antarctic Circumpolar meanders show up here — routes ride currents or fight them.

Operational models from ECMWF (European Centre for Medium-Range Weather Forecasts), NCEP/NOAA, and the US Navy's Fleet Numerical Meteorology and Oceanography Center. Every link lands on the official public viewer.
