The vorticity and inertia of rip currents have been studied. From a model of the vorticity of a rip current done at Scripps Institute of Oceanography, it was found that as a fast rip current extends away from shallow water, the vorticity of the current increases, and the width of the current decreases.
Rip currents are one of the most dangerous beach hazards, killing roughly 100 Americans per year. Here's how to identify them and stay safe over the July 4 holiday.
What is a rip current? A rip current is a fast-flowing channel of water, moving from close to the shoreline and into the ocean past the breaking waves, according to the National Weather Service ...
Rip currents: These are narrow channels of fast-moving water that flow away from shore. Undertow: This is the general return flow of water towards the ocean floor after a wave breaks. It can feel ...
A rip current statement is a warning statement issued by the National Weather Service of the United States when there is a high threat of rip currents due to weather and ocean conditions. [1] The statement usually contains some detail about when and roughly where the rip currents are most likely to be forming.
A rip current is a horizontal current. Rip currents do not pull people under the water—they pull people away from shore. Drowning deaths occur when people pulled offshore are unable to keep themselves afloat and swim to shore. This may be due to any combination of fear, panic, exhaustion, or lack of swimming skills.
In the United States, rip currents claim about 100 lives annually.
A more detailed model was later developed by Stavn describing the zooplankton aggregation where the animal orientation, dorsal light reaction and current velocity determined their region of concentration in either downwelling (due to slow current), upwelling (due to high current) and in between latter two zones (due to intermediate currents).
