Compressible vortex dynamics and shock wave interactions are central to advancing our understanding of fluid mechanics in high-speed regimes. These phenomena underpin critical applications in ...

Tsukuba, Japan—When humans kick swim through water, vortices form around their legs, generating the force that propels them forward. However, the mechanisms underlying variations in the structure of ...

An artificially colored view of Jupiter as seen in ultraviolet light. In addition to the Great Red Spot, which appears blue, another oval feature can be seen in the brown haze at Jupiter's south pole.

The polar vortex is a large area of low pressure and cold air surrounding the Earth’s poles. Under normal conditions, it spins tightly around the Arctic. However, as the Arctic warms, this system ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Flamingos, often pictured standing still with their heads submerged in water, make for a pretty picture. But peep underwater, and you’ll find the tall, elegant pink birds bobbing their heads, ...

Weaker Vortex: Conversely, a weakened vortex allows cold air and winds to migrate northward, resulting in more frequent and intense cold fronts impacting Australia. This shift is known as a negative ...
