What is the link between winter storms and global warming?

The world is getting warmer, winters included. The United States, however, has experienced severe winter storms in recent years, and experts are taking a closer look at the link between these extreme cold events and climate ...

Scientists twirl liquid light into time-periodic cluster

Researchers from Skoltech, the University of Iceland, and the University of Southampton have demonstrated the formation of an odd never-before-seen entity from the realm of quantum physics: a cluster of optical vortices with ...

Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

Ozone depletion over North Pole produces weather anomalies

Many people are familiar with the hole in the ozone layer over Antarctica, but what is less well known is that occasionally, the protective ozone in the stratosphere over the Arctic is destroyed as well, thinning the ozone ...

Researchers expand understanding of vortex spread in superfluids

An international team of scientists featuring Florida State University researchers has developed a model that predicts the spread of vortices in so-called superfluids, work that provides new insight into the physics that ...

Vortex

A vortex (plural: vortices) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the fluid are greatest at the center, and decrease progressively with distance from the center.
