Oceanweather Inc. (OWI) is pleased to announce the latest update to the Meteorological Services of Canada (MSC) long-term North Atlantic wind and wave climatology known as MSC50. The MSC50 hindcast is applied by Canadian operators for offshore operability and design, and is the standard applied by Canadian regulatory agencies for permitting. The hindcast now extends for the period of 1954 to 2018 (65 years) and provides wind and wave time series in the Canadian East Coast Maritimes.
The MSC50 hindcast has been funded by the Environment Canada and will be available via their portal at http://www.meds-sdmm.dfo-mpo.gc.ca/isdm-gdsi/waves-vagues/MSC50-eng.html for Canadian waters. The North Atlantic basin model supporting MSC50 is available from OWI as the GROW-FINE Atlantic Basin (GFAB) hindcast.
The Sentinel 3B altimeter was launched in April of 2018 and completed full commissioning in late fall of 2018. The measured data began flowing into Oceanweather’s forecast systems as of January 2019.
Data from altimeter satellites such as the Jason and Sentinel series are used to adjust the model forcing for the wave simulations. Data are both objectively and forecaster controlled for quality assurances and allow the forecaster to quickly see where the wave analysis is both higher or lower than measured. These areas can then be manually corrected to produce more accurate analysis and thus forecasted wave train simulations.
In order to support hurricane recovery activities and to improve future resiliency, Oceanweather (OWI) is in the process of producing a “fast-response” hindcast for Hurricane Michael (2018). A detailed reanalysis of the conditions experienced in a land-falling hurricane are required in any ocean response modeling to provide critical guidance on the extent of the storm wave and surge inundation. OWI can provide wind, pressure, and/or OWI’s standard wave fields for this recent event.
As experts in providing meteorological forcing for ocean response modeling of extreme wind, wave and storm surge events, OWI has a long history of quickly responding to the need for hindcasts of recent or active tropical events. This expertise is also applied in long-term operational and storm hindcasts in public and private sectors around the globe.
