In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2] The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle ...
Ekman transport is the net motion of fluid as the result of a balance between Coriolis and turbulent drag forces. In the picture above, the wind blowing North in the northern hemisphere creates a surface stress and a resulting Ekman spiral is found below it in the water column. Ekman transport is part of Ekman motion theory, first investigated ...
Cold core rings are the product of warm water currents wrapping around a colder water mass as it deviates away from its respective current. The direction an eddy swirls can be categorized as either cyclonic or anticyclonic, which is, in the Northern Hemisphere, counterclockwise and clockwise respectively, and in the Southern Hemisphere ...
Even if we stir the water and make it go clockwise, the last little bit will swirl the other way just before going down the drain. And most of us have heard the claim that the water swirls the ...
In physics, the Coriolis force is an inertial (or fictitious) force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object.
Eddy pumping is a component of mesoscale eddy -induced vertical motion in the ocean. It is a physical mechanism through which vertical motion is created from variations in an eddy's rotational strength. Cyclonic (Anticyclonic) eddies lead primarily to upwelling (downwelling). It is a key mechanism driving biological and biogeochemical processes ...
Low-pressure area. A clockwise spinning low-pressure area or cyclone of southern Australia. The center of the spiral-shaped cloud system is also center of the low. A low-pressure system over Iceland. In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations.
This makes the water stay still instead of moving. When they are created, vortices can move, stretch, twist and interact in complicated ways. When a vortex is moving, sometimes, it can affect an angular position. For an example, if a water bucket is rotated or spun constantly, it will rotate around an invisible line called the axis line.
