(1) Long-interval variations in velocity and pressure in fluid flow, not necessarily periodic, perhaps even transient in nature. (2) The name applied to WAVE motion with a period intermediate between that of an ordinary wind WAVE and that of the TIDE. (3) Changes in WATER LEVEL as a result of meteorological forcing (wind, high or low barometric pressure) causing a difference between the recorded WATER LEVEL and that predicted using harmonic analysis, may be positive or negative.
A transient prominence produced by flares or very active regions, appearing as a moderate to large collimated jet of gas rising up from the surface. Surge ejected gas will often fall or draw back onto the sun tending to follow magnetic field lines, while at other times it will rise and disperse, fading from view.
A short-term increase in incoming voltage, typically lasting at least 1/120 of a second. Surges are usually caused when items that draw a large amount of electricity (air conditioners, refrigerators, copiers, etc.) are turned off. The extra power that these items were using is then released back into the power lines. Surges occur frequently, but can be of such short duration, that you may not notice them. Surges can cause damage to your computer, as well as corrupt your data.
A rapid increase in voltage or current by a power source. Can destroy a timer if not limited. Temperature range end limits (Tolerance) – The minimum and maximum temperature which can not be exceeded during storage or operation in order to assure reliable operation of device.
A type of electrical overstress. In the absence of protective devices, the magnitude of the peak voltage of a surge is usually understood as at least twice the normal system voltage, and the duration of the overvoltage is less than a few milliseconds. (The word "surge" is also used by some engineers and technicians to indicate what should properly be called a swell.)
A brief increase in the voltage that powers home theater components. Surges are caused by lightning strikes or utility company power distribution problems. Surges not only travel on the AC utility line but every line that connects TVs and home theater systems to the outside world, including coaxial, antenna, satellite, phone and network lines. Depending on the severity of the surge, it can cause a TV or component to reset or can cause catastrophic, irreparable damage. Surge Suppressors and UPS Systems both provide protection against surge damage.
Surge (Noriko "Nori" Ashida) is a fictional character, a mutant in the Marvel Universe, one of the student body in the Xavier Institute, and a member of the former New Mutants squad therein. She maintained her powers post M-Day and is the leader of the New X-Men. She first appeared in New Mutants (volume 2) #8.
Is the reversal of flow within a dynamic compressor that takes place when the capacity being handled is reduced to a point where insufficient pressure is being generated to maintain flow. Also known as pumping. ( 030)
A short-lived, frequently large-scale, increase in the rate of movement of the ice within a glacier. Ice velocities may increase 10 to 100 times above normal flow rates. In some surges, the terminus of a glacier rapidly advances. Although not all glaciers surge, those that do often surge with some sort of a periodicity. ------------------------------- T-Z Tarn A lake that develops in the basin of a cirque, generally after the melting of the glacier.
A ring-shaped cloud of gas and suspended solid debris that moves radially outward at high velocity as a density flow from the base of a vertical eruption column accompanying a volcanic eruption or crater formation.
(1) A sudden swelling of discharge in unsteady flow. (2) A large mass of moving water, such as a wave or swell. Also a heavy, violent swelling motion, such as a surge of water through a storm drain during a heavy rain.
1. See storm surge See surge current See surge line. 4. In hydrology, a sudden change in discharge resulting from the opening or closing of a gate that controls the flow in a channel, or by the sudden introduction of additional water into the channel. 5. The fore and aft movement of the center of gravity of a ship. See heave, sway, ship motion. 6. Water transported up a beach by breaking waves.
Glacial surges are short-lived events where a glacier can move up to velocities 100 times faster than normal, and advance substantially. Surging glaciers are clustered around a few areas. High concentrations of surging glaciers can be found in Svalbard, Canadian Arctic islands, and Alaska.
Surge (also SURGE) is a citrus soft drink first introduced in Norway, under the name Urge (1996), by the Coca-Cola Company to compete with Pepsi's Mountain Dew. However, while Mountain Dew is a yellow color, Surge is green in color. It became very popular in Norway.
The increase in sea water height from the level that would normally occur were there no storm. Although the most dramatic surges are associated with hurricanes, even smaller low pressure systems can cause a slight increase in the sea level if the wind and fetch is just right. It is estimated by subtracting the normal astronomic tide from the observed storm tide.
Surge is the name of an advanced game engine--includes graphics, sound, physics, scripting, networking, and more. Surge is also the name for the first game for this engine, which will be based on a replacement until the Surge Engine becomes viable.
