Figure 3-31. Typical Hurricane Wave Spectra. Typical Hurricane 

 Wave Spectra from the Atlantic Coast of the United 

 States. The ordinate scale is the fraction of 

 total wave energy in each frequency band of 0.0011 

 Hertz (one Hertz is one cycle/second). A linear 

 frequency scale is shown at bottom of each graph 

 and a non-linear period scale at top of each graph.
