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.
A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. [1] [clarification needed] Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms (/ ˈ m eɪ l s t r ɒ m,-r ə m / MAYL-strom, -strəm).
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 ...
The city's zoo called for volunteers to help pack sandbags to protect animal enclosures and employees and volunteers began to move some of the 450,000 books from the city's main church archive to ...
Astronomers used the Hubble Space Telescope to make a landmark discovery of water vapor in the atmosphere of a planet just twice Earth’s diameter in size.
Mode-water eddies have a complex density structure. Due to their shape, they cannot be distinguished from regular anticyclones in an eddy-centric (focused on the core of the eddy) analysis based on sea level height. Nonetheless, eddy pumping induced vertical motion in the euphotic zone of mode-water eddies is comparable to cyclones.
Well, there's this cutie little feature called Uber Reserve, which allows you to reserve rides to and from the airport at a locked-in price (major 🔑) anywhere from 30 minutes to 90 days in ...
Most whitewater kayaks are made of plastics now, although some paddlers (especially racers and "squirt boaters") use kayaks made of fiberglass composites. Whitewater kayaks are fairly stable in turbulent water, once the paddler is skillful with them; if flipped upside-down, the skilled paddler can easily roll them back upright.
