«The lattice Boltzmann method allowed us to identify regions of low air flow and places where vortices of air flow formed,» study coauthor Sungchan Hong says.

But an international team of scientists now finds that water flows over the bony carapaces of these fishes much as air does over the space shuttle, creating vortices of water that help guide the fish while swimming in unpredictable waters.

A new study published in the European Journal of Physics reports the findings of a research team at the University of Tsukuba that established a new computational modeling approach that provides precise 3D data on air flow, vortex formation, and lift around a skier's body.

As the air flows around your arm, it forms vortices that come off the top and bottom of your arm in an alternating fashion.

The bright clouds form when the flow of ambient air is perturbed and diverted upward over the dark vortex, causing gases to likely freeze into methane ice crystals.

Because contraction of the vortex tends to require faster rotation (conservation of angular momentum), which increases centrifugal acceleration, which opposes contraction, it becomes hard for air to flow in sideways to take the space of warmer air that is rising when the air is spinning; thus, a rising column of air can pull up on air from below.

The polar vortex is a fast flowing stream of air that circles the North Pole during the winter months in the upper atmosphere, known as the stratosphere.

The atmosphere above the Arctic in particular was out of whack: «High pressure replaced low pressure over the Arctic, and the Polar Vortex weakened and even reversed at times, with a clockwise flow of air replacing the usual counter-clockwise flow of air.

The reason air moves in the west to east direction for both the weak and strong vortex cases of Figure 1 is that the rotation of the Earth is important to the flow.
