The ekman spiral describes

The oceanic, wind driven Ekman spiral is the result of a force balance created by a shear stress force, Coriolis force and the water drag. This force balance gives a resulting current of the water different from the winds. In the ocean, there are two places where the Ekman spiral can be observed. At the surface of … See more In order to derive the properties of an Ekman spiral a look is taken at a uniform, horizontal geostrophic interior flow in a homogeneous fluid. This flow will be denoted by See more The equations and assumptions above are not representative for the actual observations of the Ekman spiral. The differences between the theory and the observations are that the angle is between 5-20 degrees instead of the 45 degrees as expected and that … See more The solution for the flow forming the bottom Ekman spiral was a result of the shear stress exerted on the flow by the bottom. Logically, wherever shear stress can be exerted on a flow, Ekman spirals will form. This is the case at the air-water interface, because … See more Web3/9/2024 Chap 7 Part C Why do the lengths of the arrows in the Ekman spiral get shorter and shorter as you move deeper into the water column? Hint 1. What is the Ekman spiral? The Ekman spiral describes the speed and direction of the flow of surface waters at various depths. ANSWER: The Coriolis effect weakens as depth increases. The temperature gets …

WebThe Ekman spiral is a phenomenon in oceanography that describes the gradual change in direction and magnitude of ocean currents with increasing depth beneath the surface. The spiral is caused by the Coriolis effect, which results from the Earth's rotation, and the frictional drag of winds on the surface of the ocean. WebThe Ekman spiral is a graphical representation of the earth's wind patterns. It was developed by Swedish meteorologist, Vagn Walfrid Ekman in 1904. ...

WebExpert Answer. Describe how the Ekman spiral forms. 1 point As the wind blows over an open stretch of ocean, the surface water beneath it is set in motion. Due to the movement of surface water, water below, at least several hundreds of meters below, moves as well, leading to major surface ocean currents. The Coriolis force (CF) bends the moving ... WebEkman transport moves the surface layer 90 o to the right of the wind, meaning the net Ekman transport is in an offshore direction. The water displaced near the coast is replaced by cold, nutrient-rich deeper water that is brought to the surface through upwelling, leading to high productivity (Figure 9.5.3).
