Like terrestrial hurricanes, the plasma cyclone had a quiet "eye," a funnel and counterclockwise-spinning spiral arms — but, instead of raining water, the vortex showered the upper atmosphere ...

Answer (1 of 7): There is a long and storied history to the idea of using a cowling to concentrate or increase apparent airflow over a wind turbines blades. All the way back in the 1970's folks were looking at his idea. None of these efforts have proven financially or commercially viable as of y...

In fluid dynamics, a vortex (plural vortices/vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil.. Vortices are a major component of turbulent flow.

Abstract The high formation frequency and previously documented life cycle of Florida Keys' waterspouts result from energy and angular momentum cascades through five scales of atmospheric motion, namely the funnel, spiral, cumulus, cloud-line and synoptic scales. The funnel scale appears to be the most complicated in that pronounced horizontal and vertical …

2. Tornadoes are intense atmospheric vortices, often made visible by very small water droplets that condense as air swirls into the vortex. The object of this exercise is to make certain deductions about the distribution and speed of tornadic winds from observations of the geometry of the condensation funnel.

The capillary-scale aerated tubes formed out of the free surface waves curving into the funnel while also drawing in air, and the double helix (DH) contra-rotating vortex tubes formed at the trailing edge root, are all twisted together like a torsional spring over a duration of $1/4$ th the time period of oscillation at both 1 Hz and 1.25 Hz ...

· Wind Shear: The fast-moving winds are responsible for rolling air below into a horizontal vortex (a spinning tube) above the opposite surface wind. · Updraft: The air which is warmed up by the sun near the ground begins to lift a section of the horizontal vortex into a vertical position.

'A tornado is a rotating column of air, pendant from a cumulonimbus cloud, and nearly always observable as a funnel cloud or tuba. Its vortex, meters in diameter, rotates counterclockwise in the northern hemisphere, and clockwise in the southern hemisphere, with wind speeds of 160 to more than 480 kilometres per hour.';

They call it the Vortex Wind Funnel. Its unique funnel shape is the reason for its amazing results. For years people have known that funnelling the wind could increase its power on a focused point. But the common logic was that a funnel would be heavy and difficult to align with the wind. Well, the guys at Master Flo Technology didn't think so.

A tornado is one of Earth's most devastating spectacles. Formed from the violent convergence of cold and warm air, unstable air pressures create a swirling funnel-shaped cloud; a vortex of wind leaving destruction in its wake. Whirling winds can reach 300 mph (nearly 500 kph) and damage paths can be in excess of one mile (1.6 km) wide.

A tornado is a vortex of wind rotating violently, that creates a funnel-shaped cloud which moves in a narrow path over land, as part of a large storm system.. Each year, approximately 1,000 tornadoes are recorded in the US, according to the National Oceanic and Atmospheric Administration. Amazingly, this makes the US the most tornado-prone country in …

This study demonstrates the use of two types of pendulums on a vortex bladeless wind (VBW) turbine: arc-shaped and disc-shaped. Here, the kinetic energy of the wind as input to the VBW turbine gets converted into useful electrical energy for both types of pendulums. Permanent magnets are attached to the pendulums and act as a piston to the generator, while …

Vertical and temporal variations of three-dimensional wind velocity associated with an upper-tropospheric cold vortex-tropopause funnel system were observed by an MST radar in Japan (the MU radar). Marked changes of vertical velocity and horizontal wind direction were found between the inside and outside of the cold vortex.

Whole city blocks could be laid out to funnel wind into high velocity areas. Imagine spiral shaped sky scrapers with wind turbines at the center top. The tops of these large spiral shaped, vortex inducing structures could also have the tops painted black to increase vortex velocities via thermal lift. New extreme sports could also be developed. .

Mobile radars also have showed that tornadoes often extend outside an existing, visible funnel. At what wind speed of the cloud-to-ground vortex does a tornado begin? How close must two or more different tornadic circulations become to qualify as a one multiple-vortex tornado, instead of separate tornadoes? There are no firm answers.

Low pressure in the vortex causes a rotating funnel cloud of air and dust to form, with wind speeds that typically range from 75 to 100mph (120 to 180km/h). These are the deadliest tornadoes of ...

Marked changes of vertical velocity and horizontal wind direction were found between the inside and outside of the cold vortex. The vertical velocity activity outside the …

Cold-air funnel clouds, and its associated vortex of wind, are generally much weaker than the vortex produced by supercells.Although cold-air funnels rarely make ground contact, surface-level vortices sometimes become strong enough for condensation cloud to "touch down" briefly, becoming visible as weak tornadoes or waterspouts.. Unlike the related phenomenon …
