Depending on context, wave height may be defined in different ways: • For a
sine wave, the wave height
H is twice the
amplitude (i.e., the
peak-to-peak amplitude):
Significant wave height RMS wave height Another wave-height statistic in common usage is the
root-mean-square (or RMS) wave height
Hrms, defined as: H_\text{rms} = \sqrt{ \frac{1}{N} \sum_{m=1}^N H_m^2}, with
Hm again denoting the individual wave heights in a certain
time series. == See also ==
