sea_surface_wind_wave_significant_height

Wind waves are waves on the ocean surface and are the high frequency portion of a bimodal wave frequency spectrum. Wave height is defined as the vertical distance from a wave trough to the following wave crest. Significant wave height is a statistic computed from wave measurements collected during an observation period that approximates to the wave height that would be recorded visually by a human observer during that observation period.

significant_height_of_wind_waves

Height is the vertical distance above the surface. Wind waves are waves on the ocean surface. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.)
