B35-B37. Data for 1980 through 1983 are in Figures B12-B14, 

 B28-B30, and B41-B43. 



g. Peak spectral wave period distribution. Annual, seasonal, and 

 monthly peak wave period T distributions histograms for 1983 

 are presented in Figures B6-B8, B25, B26, B38, and B39; data for 

 1980 through 1983 are in Figures B15-B17, B31-B32, B44, and B45. 



h. Persistence of wave heights. Tables B6, Bl6, and B26 show the 

 number of times throughout 1983 when the specified wave height 

 was equaled or exceeded at least once during each day for the 

 duration (consecutive days) indicated; data for 1980 through 

 1983 are in Tables B11, B21, and B31. For example. Table B6 for 

 gage 625 (pier end Baylor) indicates wave heights equaled or ex- 

 ceeded 1.0 m, 41 times for at least 1 day; 34 times for at least 

 2 days; 25 times for at least 3 days; 18 times for at least 

 4 days, etc. Therefore, on seven occasions it was expected for 

 the height to have equaled or exceeded 1.0 m for 1 day exactly; 

 on nine occasions for 2 days; on seven occasions 3 days; etc. 

 Note that the height exceeded 1,0 m, 41 times for 1 day or 

 longer, while heights exceeded 0.5 m only 26 times for this same 

 duration. This occurred because the longer durations of lower 

 waves may be interspersed with shorter, but more frequent, 

 intervals of higher waves. For example, the one time that wave 

 heights exceeded 0.5 m for 64 days may represent 5 or 10 

 different times the height exceeded 1 m for shorter duration. 



i. Wave roses. For the pier-end Baylor gage (625), wave roses 

 showing the distribution of wave height versus approach angle 

 are presented. Data for 1983 are in Figures B9 and BIO, while 

 1980 through 1983 data are in Figures B18 and B19. The angles 

 are referenced to true north. Northerly wave angles (e.g;, less 

 than 70 deg) generally produce southward currents while south- 

 erly wave angles greater than 70 deg produce northward currents. 



J. Spectra. Spectra for the pier-end Baylor gage (625) for days 

 when wave heights exceeded 2 m are presented in the last fig- 

 ure. The plots show energy density as a function of wave 

 frequency.
