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).
Oceanic eddies are also usually made of water masses that are different from those outside the eddy. That is, the water within an eddy usually has different temperature and salinity characteristics to the water outside the eddy. There is a direct link between the water mass properties of an eddy and its rotation.
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.
Plunge pools are often very deep, generally related to the height of the fall, the volume of water, the resistance of the rock below the pool and other factors. [4] The impacting and swirling water, sometimes carrying rocks within it, abrades the riverbed into a basin, which often features rough and irregular sides. Plunge pools can remain long ...
A team of Spanish engineers developed machinery that can extract water from thin air in hot and dry areas, AccuWeather Senior On-Air Meteorologist Adam Del Rosso reported on AccuWeather Prime.
The shape formed by the free surface is called a hyperboloid, or "Gabriel's Horn" (by Evangelista Torricelli). The core of a vortex in air is sometimes visible because water vapor condenses as the low pressure of the core causes adiabatic cooling; the funnel of a tornado is an example. When a vortex line ends at a boundary surface, the reduced ...
It is created by the erosional forces of turbulence generated by water falling on rocks at a waterfall's base where the water impacts. [2] Potholes are also sometimes referred to as swirlholes . This word was created to avoid confusion with an English term for a vertical or steeply inclined karstic shaft in limestone .
In March, a mother was horrified to find a pedophile symbol on a toy she bought for her daughter. Although the symbol was not intentionally placed on the toy by the company who manufactured the ...
