Kodor river plume. A river plume is a freshened water mass that is formed in the sea as a result of mixing of river discharge and saline seawater. [1] River plumes are formed in coastal sea areas at many regions in the World. River plumes generally occupy wide-but-shallow sea surface layers bounded by sharp density gradients.
[11] [10] [12] At the boundary between this freshwater plume and the surrounding seawater, strong gradients in salinity and density will form. [13] An example of such a front is located in the Chesapeake Bay estuary, but these fronts are also common in front of river outlets such as the Mississippi, Amazon, or Connecticut River. [14]
Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...
Its advancing boundary, often called a plume edge, can intersect with groundwater wells and surface water, such as seeps and springs, making the water supplies unsafe for humans and wildlife. The movement of the plume, called a plume front, may be analyzed through a hydrological transport model or groundwater model.
The East Asian rainy season (Chinese and Japanese: 梅雨; pinyin: méiyǔ; rōmaji: tsuyu/baiu; Korean: 장마; romaja: jangma), also called the plum rain, is caused by precipitation along a persistent stationary front known as the Meiyu front for nearly two months during the late spring and early summer in East Asia between China, Taiwan, Korea and Japan.
The mantle plume hotspot that is half the cause of Iceland's intense volcanism (the other half being the Mid-Atlantic Ridge) is believed to have been the cause of the largest mass extinction event ...
The ash is sucked into the engines, where it is melted by the heat of the engine, Power said. The melted ash then coats the inside of the engine, ultimately leading to engine failure.
The bearskin cap used by the unit features a copper front plate shaped like a half-sun. A white plume is attached to the left of the bearskin cap, although the cap used by the unit's commander will feature a unique plume to indicate rank. [2] An orange cockade is also placed on the left. The front of the cap also equipped with a black leather ...
