An extraterrestrial vortex is a vortex that occurs on planets and natural satellites other than Earth that have sufficient atmospheres. Most observed extraterrestrial vortices have been seen in large cyclones, or anticyclones. However, occasional dust storms have been known to produce vortices on Mars and Titan. [1]
A mesoscale convective vortex (MCV) is a low-pressure center within a mesoscale convective system (MCS) that pulls winds into a circling pattern, or vortex. With a core only 30 to 60 mi (48 to 97 km) wide and 1 to 3 mi (1.6 to 4.8 km) deep, an MCV is often overlooked in standard surface observations . [ 7 ]
Each vortex, whether driven by heat, wind, fire, snow or water, highlights the intricate processes at work in our environment. While some, like dust devils and snow devils, pose minimal danger and ...
A low precipitation supercell in rural Northeast Colorado.. A supercell is a thunderstorm characterized by the presence of a mesocyclone, a deep, persistently rotating updraft. [1]
The possible effects of climate change are far worse, and could strike far sooner, than we previously thought, according to Dr. James Hansen, a leading climate change researcher who was among the ...
A stretched polar vortex event played a significant role in the Arctic outbreak that froze Texas in February 2021, killing more than 200 people, according to a 2020 study.
In general, vortex lines (in particular, the axis line) are either closed loops or end at the boundary of the fluid. A whirlpool is an example of the latter, namely a vortex in a body of water whose axis ends at the free surface. A vortex tube whose vortex lines are all closed will be a closed torus-like surface.
The polar vortex is a whirling cone of low pressure over the poles that's strongest in the winter months due to the increased temperature contrast between the polar regions and the mid-latitudes ...
