MAXIMUM WINDS AND WAVES 



A STUDY OF WEATHER MAPS FOR THE LAST TWENTY YEARS 

 HAS YIELDED THE RESULTS SHOWN IN TA8LE "I". THE 

 WAVE PREDICTIONS IN THIS TABLE ARE BASEO ON A STUDY 



MADE AT New York University for the Bureau of Aero- 

 nautics, United States Navy, the results of which 

 are contained in "Practical Methods for Observing 

 AND Forecasting Ocean Waves", July 1953-

NOTE: During these maximum storms 80^ of all waves will 



BE less than 0.7 TIMES THESE HEIGHTS, BUT SINGLE 

 MAXIMUM WAVES MAY BE I. 5 TIMES HEIGHTS LISTED. 



It WILL BE NOTED IN TABLE "I" THAT THE MAXIMUM WIND 

 occurred DURING A HURICANE AT A VELOCITY OF |20 

 MILES PER HOUR AND THAT THE COMPUTED AVERAGE HEIGHT 

 OF THE 10^ HIGHEST WAVES IS 66 FEET DURING AN EAST- 

 ERLY STORM. The computed wave heights are based on
