题目The ocean is always moving:waves break on the surface,sea levels rise and fall with the tides,and currents flow below the surface.Although it looks as if the water in a wave is moving across the surface of the ocean,it is not.The water is actually moving up and do...
Imagine sitting in a boat in the ocean. The sky is blue, the sun is out, and the water is clear. Suddenly, you notice something moving in the water, so you stand up to get a closer look. 【1】 And it’s a fast swimmer. It jumps out of the water and then it’s gone. You’...
But surprisingly, the amount of energy that would be dissipated in this way and the effectiveness of this process in generating tidal winds are questions that have never been asked. Tidal winds are generally considered only as an S2 component in the upper atmosphere due to thermal heating rather...
By the way, if you have a setting Sun illuminating the cloud where some of the blue light has already been scattered out, it may be that the cloud is illuminated by red light. In that case, the cloud would Appear red as well. But the point here is that under Mie scattering, it sca...
Labrador Current: It flows from the Arctic Ocean towards the south and meets the warm northward moving Gulf Stream. The combination of cold Labrador Current and warm Gulf Stream is known for creating one of the richest fishing grounds of the world. Canary Current: Low salinity current extending...
Barrier islands constantly change as longshore currents keep picking up, moving and redepositing sand. Rip currents are another type of coastal current that form where underwater land formations prevent waves from flowing straight back out to sea. You've probably seen signs posted at the beach, ...
As wind blows over the ocean, it drags the top layers of water along with it. That moving water pulls on the layers underneath, and those pull on the ones beneath them. In fact, water as deep as 400 meters is still affected by the wind at the ocean’s surface. If you zoom out ...
The waves we know are mostly produced by winds blowing over the sea. They are directly connected with the wind speed and the time that wind lasts.Sometimes ocean life can be seen in the wave. Living things seem to be staying within the wave, moving slowly inside it as if they were ...
And these are the wind driven currents. The Brazil Current runs down the coast of Brazil, the Peru Current runs up the coast of Peru, the California Current, the Alaska Current, the West Australian Current, the East Australian current. When I say they're geostrophically driven, or geostrop...
The ice dampens surface and internal waves and decreases the transfer of wind momentum to the water. But as the ice thins and the margins retreat toward the North Pole, the effect of the winds is increasing. For instance, prior to the past 20 years of diminishing sea-ice cover, the ...
