APPENDIX D: STORM DATA 

 Explanation of Storm Data Displays 



1. Whenever the wave height PL exceeded 2.0 m at the seaward end 



•"o 

 of the Field Research Facility (FRF) pier, data were collected hourly. The 



available data for the 24 storms (reported in Part VI of the main text) are 



presented in Figures D1-D24. 



Atmospheric Pressure 



2. Reported in millibars, these data are useful for documenting the 

 type of storm, the passage of fronts, and the intensity of the atmospheric 

 pressure system. 



Wind Speed 



3. Local winds are generally responsible for the wave conditions at the 

 FRF. Wind speed is reported in metres per second. 



Wind Direction 



4. Referenced to true (star) north, the wind direction indicates the 

 direction from which the winds are blowing, e.g., winds blowing from west to 

 east are referred to as having an angle of 270 deg. 



Wave Direction 



5. Referenced to true (star) north, the wave direction measurements are 

 taken at the seaward end of the FRF pier. The pier axis (considered perpen- 

 dicular to the beach at the FRF) is oriented 70 deg east of true north; con- 

 sequently, wave angles greater than 70 deg imply the waves were coming from 

 the south side of the pier.
