Abstract:
SOWM Hindcast Wind and Wave Climatology for North Pacific, North Atlantic and Mediterranean is historical digital data set DSI-9786, archived at the National Climatic Data Center (NCDC). It is a digital ocean atlas. SOWM is the Spectral Ocean Wave Model, a computer software methodology which was developed by Dr. Willard J. Pierson and others and adopted in December 1974 by what was then the US Navy Fleet Numerical Oceanography Center (FLENUMOCEANCEN). FLENUMOCEANCEN was a predecessor of the current Fleet Numerical Meteorology and Oceanography Center (FNMOC). SOWM is a computer-based procedure that produces a directional variance spectrum at specified grid points that are a maximum of 180 nautical miles apart. This spectrum defines the sea surface at each grid point through a two dimensional matrix (direction/ frequency) of 12 directions and 15 frequency bands. The David Taylor Naval Ship Research and Development Center (DTNSRDC), a predecessor to the US Naval Surface Warfare Center, Carderock Division (NSWCCD), with Operations Research, Inc. (ORI), developed computer programs to derive a number of numerical parameters from the SOWM spectral wave data. The NCDC used many of the concepts from these programs and others written by FLENUMOCEANCEN to devise a parameterization program that was used for this atlas (DSI-9786). This atlas contains climatological summaries for seven parameters: wind speed and direction, wave height, wave direction, wave slope code, modal wave period, and wave directionality. The first four parameters had appeared in US Navy climatologies. The latter three parameters had not appeared, because they cannot be directly derived from visual observations. However, they can be very important operating considerations. Ship rolling and stability is affected by the wave slope of higher waves. Wave slope of a regular wave is defined as the ratio of wave height to wave length. The modal wave period is the period associated with the maximum wave energy in the wave spectrum. Modal wave periods associated with wavelengths of about 0.75 and 1.25 ship lengths (depending on ship course and speed) can cause resonance pitching and heaving. The modal wave is not necessarily equal to the wave period associated with the higher of the two waves, the sea or the swell as summarized in past US Navy climatologies (US Navy, 1974). Wave directionality is the uniformity of the direction of movement of the waves. If the waves are all moving in a uniform direction, then the directionality is one. When there is no preferred direction of wave movement (a completely confused sea state), the directionality is zero. Obviously, ship response and maneuverability can be affected by the directional spread of the wave energy. Data in this atlas are derived using winds and waves from the period January 1973 to December 1982, i.e. 10 years. To make a wide range of climatic data available to researchers and the public.
