Question

Difference wave height and significant wave height

Answer 1

In physical oceanography, thesignificant wave height (SWH or Hs) is defined traditionally as the mean wave height (trough to crest) of the highest third of the waves (H1/3). ... Thesignificant wave height may thus refer to Hm0 or H1/3; the difference in magnitude between the two definitions is only a few percent
