The solar vortex engine prototype at Universiti Teknologi PETRONAS. The concept of a vortex engine or atmospheric vortex engine (AVE), independently proposed by Norman Louat [1] and Louis M. Michaud, [2] aims to replace large physical chimneys with a vortex of air created by a shorter, less-expensive structure.
A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; ... Journal of the Atmospheric Sciences. 43 (13): ...
The Crow instability of a jet aeroplane's contrail visually demonstrates the vortex created in the atmosphere (gas fluid medium) by the passage of the aircraft. A key concept in the dynamics of vortices is the vorticity , a vector that describes the local rotary motion at a point in the fluid, as would be perceived by an observer that moves ...
The potentially life-threatening cold is due to the disrupted polar vortex. The FOX Forecast Center said a lobe of the polar vortex will dip to the south and move into the U.S. this weekend and ...
" The polar vortex is a basic fixture of the Earth's atmosphere," AccuWeather Meteorologist La Troy Thornton said. As the name implies, the polar vortex phenomenon occurs at the Earth's poles.
- The polar vortex doesn't always mean snow: Temperatures on the ground still have to be cold enough for snow production. If the atmosphere is too dry or too warm, you'll miss out on the snow.
The polar vortex is circled by the polar night jet. The warmer air can only move along the edge of the polar vortex, but not enter it. Within the vortex, the cold polar air becomes increasingly cold, due to a lack of warmer air from lower latitudes as well as a lack of energy from the Sun entering during the polar night. [112]
The hazy atmosphere that Titan has leaves the moon unilluminated in the Sun's rays but the image of the vortex showed a bright spot on the south pole. Scientists derived that the vortex is high up in the atmosphere, possibly above the haze, because it can still be illuminated by the Sun. [31]
