![]() The video's complete transcript is available here. The level of the tides is exaggerated in order to show how the tides vary around the world. Tidal waves are regular ocean waves, and are caused by the. The data used in this visualization run for slightly longer than one Earth day. Tsunamis do not necessarily make their final approach to land as a series of giant breaking waves. With that knowledge, plus near-perfect knowledge of the motion of the Sun and Moon, the tide can be predicted at any location and at any time in the future. After several years collecting data, researchers could analyze the signals at each ocean location to determine the tidal characteristics. Altimeters on these missions acted as flying tide gauges. The Topex/Poseidon and Jason satellite altimeter missions were designed to observe and record this complexity. Waves are trapped and rotating around New Zealand, causing a high tide on one side of the islands with a simultaneous low tide on the other side. In the North Atlantic, we see waves mainly rotating anti-clockwise, with small amplitudes in the middle of the ocean and high amplitudes around the boundaries, especially along the coasts of northwest Europe and Britain. Even there, we see a complicated pattern as waves merge from the north and others separate northwards or southwards under Antarctic ice shelves. Waves run relatively unimpeded westward only around Antarctica. Detailed ocean or sea water wave cartoon vector illustration in vintage japanese engraving style isolated on white background. This animation shows the tides as a complex system of rotating and trapped waves with a mixture of frequencies. If our planet had no continents, tides would be hemispheric-sized bulges of water moving westward with the moon and sun.
