About Research Forecasting MetOcean Studies Software Current Marine Data








In 1983, Oceanweather (OWI) was approached to produce a wind and wave forecast for the Discoverer Seven Seas which was one of the largest drillships in the world. OWI had already built a reputation for pioneering the hindcast approach in developing metocean criteria for structure design as well as developing new wind, wave and tropical models. The result was the first operational forecast system which computed vessel response, an approach that is being "rediscovered" even today.


Significant Wave Height Forecast

Since then, OWI forecasting has expanded rapidly. In the late 1980's the operational forecast was extended to the North Atlantic and North Pacific. A partnership with Ocean Systems produced the first onboard optimum ship routing system which has continued to evolve into today's Vessel Optimization and Safety System (VOSS). In the 1990's forecasting was extended to global coverage and regional high-resolution nested models began operational use. The first global wave graphics on the Internet appeared in 1994 as Oceanweather unveiled its Current Marine Data web site for the maritime community.


CYCLOPS Storm Track

Today, OWI runs its global wind and wave models twice per day out to a forecast horizon of 10 days. Multiple high-resolution nested wave models are run up-to 4 times per day to service such products as the Oceanweather Display System, CYCLOPS and provide weather data and graphics to companies worldwide. We continue to improve the models and techniques used in producing our forecasts and remain at the cutting edge of global marine forecasting.


OWI has always maintained that the best forecasts are produced by experienced marine meteorologists. Hence, the OWI operational forecast system has evolved to provide the best possible tools for our forecast team.

Forecast data and marine observations are collected by OWI via satellite feeds and the Internet. Model data from the NCEP (US), US Navy, ECMWF (Europe) and others are routinely evaluated by the forecast team. Observational data from buoys, ships, coastal stations, and satellite measurements of winds and waves are incorporated in the Wind WorkStation (WWS) for both global and regional applications. Tropical forecasts from national centers are used to drive OWI's tropical model which produces high-resolution tropical wind fields. All of this data is presented in the WWS where the forecaster evaluates the current situation and makes enhancements to the marine surface wind fields.

The enhanced wind fields are then run through one of OWI's spectral wave models. Currently, our global model is run twice per day and several high-resolution nested models are run up-to 4 times per day. The resulting wave fields are then validated in realtime against all available observational data.

Output from OWI's forecast is used for a variety of purposes, many of which are detailed on our main forecast web page. We provide operational data for container vessels, offshore oil platforms, web sites, onboard display programs, in-house applications and many others.

Archived data is routinely used for post-voyage analysis, tow simulations and other applications that require near-realtime wind and wave data.
