ORLANDO, Fla. – When you hear meteorologists talk about a polar vortex breakdown, it might sound like something that only affects the Arctic or northern states. In reality, these events can have ...

The polar vortex is a large area of cold, spinning air that sits near the North Pole and exists year-round. When it weakens or shifts, Arctic air can spill south, increasing the risk of snow and ...

A polar vortex is expected to bring two surges of extremely cold air to the U.S. in January. The polar vertex is a large area of low pressure and cold air that sits over Earth's poles. Middle ...

The displacement of the polar vortex over the eastern half of the U.S. will usher in days of arctic cold through the end of January. The core of the polar vortex, which contains some of the coldest ...

Don't be fooled by the string of uneventful weather — the polar vortex is rebooting and will take another swing, or several, at the greater Philadelphia region, leading to a turbulent weather pattern ...

Frigid temperatures are expected to impact much of the central and eastern United States in the coming weeks. The first of three polar vortex systems is expected this month, according to AccuWeather.

High above the North Pole, in a slice of atmosphere rarely noticed and even less understood, a transformation is underway. Over the next 10 days, changes in the stratosphere will upend weather ...

This study employs potential flow theory with a discrete-vortex method to model the unsteady aerodynamics of a flat plate, with a particular focus on the coupled dynamics of leading-edge and ...
