Abstract or Summary
  • Data on ocean wave height and energy have been gathered via microseismometer at Hatfield Marine Science Center in Newport, Oregon since 1971. Data on wave characteristics at Newport for the winter seasons (November through March) from 1982 to 1990 were analyzed to ascertain any relationships with winter storm events. Newport storm data was compiled in 1991 for winter periods 1981 through 1990. In this study, that storm data is compared to wave data to quantify the spatial and temporal relationships of storms and storm waves occurring at Newport during the winters from 1982 to 1990. Statistical analysis of the two data sets provides evidence to reject the hypothesis that significantly energetic storm waves should precede significant storm events, but does not provide evidence to reject the hypothesis that significantly high waves should precede significant storm events. In general, the significant waves occurred between 28 and 34 hours after the storms had moved onshore. Thus the conclusion was that the wave energy and storm data sets do not correlate, but the correlation between the wave height and storm data sets is questionable. Other important factors for further analysis into climate-wave relations are suggested. In addition, a discourse on basic wind generated wave theory as well as discussion on the use of the microseismometer as a data gathering tool are included.
