What causes ocean waves? - NOAA Ocean Exploration
网页There are a few types of ocean waves and they are generally classified by the energy source that creates them. Most common are surface waves, caused by wind blowing along the air-water interface, creating a disturbance that steadily builds as wind continues to blow and the wave crest rises.
Waves - National Oceanic and Atmospheric Administration
网页2023年9月20日 · The waves in a fully developed sea outrun the storm that creates them, traveling great distances from the wind source and lengthening and reducing in height in the process. These lower frequency waves are called swell waves. Swells organize into groups smooth and regular in appearance.
Ocean Waves | CMEMS - Copernicus
网页Ocean waves exist at the sea surface and act as a buffer for exchanges between the ocean and the atmosphere. The energy of a wave is driven by the wind and propagated from one region to another, until waves break and their energy is released. By doing so, ocean waves participate in climate regulation.
Why does the ocean have waves? - NOAA's National Ocean Service
网页2024年6月16日 · Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides. The ebb and flow of waves and tides are the life force of our world ocean.
Breaking Waves - NOAA Ocean Exploration
网页Waves in the lonely stretches of the open sea are little noticed by anyone but the occasional sailor. But once they reach shore, they become much more interesting. When waves break, or become unstable and topple forward, they thrill …
Ocean Waves: Energy, Movement, and the Coast - ThoughtCo
网页2020年1月22日 · Learn about what causes ocean waves, which are caused by the friction of wind over open ocean water, how energy moves them, currents and more.
What are Ocean Waves? How are Ocean Waves Measured?
网页Ocean Waves are disturbances in the surface of the ocean. They can be created by wind, gravity, or other displacements of water. Satellites typically measure significant wave height, which is the average wave height of the highest third of waves in a given sample period.
