![]() When the crest and trough of two different waves meet head-on, they can cancel each other out, resulting in a flat sea. One explanation is that wave trains travel thousands of miles across ocean basins, encountering other wave trains as they move. Scientists do not completely understand how rogue waves form. Rogue waves are often steep with very deep troughs. These rogue waves can be incredibly huge and extremely dangerous. Sailors throughout history have described these sudden “walls of water” out at sea. Waves organize themselves by wavelength, forming a series of waves that pass in a regular pattern, known as a wave train.īut sometimes giant waves seem to appear out of nowhere. Stronger winds, such as those that blow during storms, tend to produce waves with longer wavelengths, which move faster than waves with shorter wavelengths. Waves become more organized and begin traveling in one direction. As the wind continues to blow, the sea surface becomes rougher. Waves form when wind energy in the atmosphere is transferred to the sea surface. Wave height is measured from crest to trough. Wavelength is measured from crest to crest or trough to trough. The highest part of a wave is called its crest the lowest part is a trough. ![]() Waves are also caused by events such as undersea earthquakes, calving glaciers, and landslides.Ī drawing of a typical wave features a top and a bottom. Typically, this energy comes from the wind and is transferred to the water. When we observe an ocean wave, what we see is a disturbance in the water caused by the transfer of energy. The ocean’s waves range from tiny, fleeting ripples to tremendous, booming curls.
