First, it disturbed the atmosphere in just the right way to set off an undulation in the jet stream — a river of very strong winds in the upper atmosphere — that atmospheric scientists call a Rossby ...

High-pressure systems are an intrinsic part of an atmospheric Rossby wave, and they travel along with the wave. Heatwaves occur when the high-pressure systems stop moving and affect a particular ...

In physics, a breaking wave is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be dissipated.

The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the sun, according to a new study. The same kind of large-scale ...

Weather conditions on Earth are influenced by a phenomenon known as Rossby waves. These planetary-scale fluctuations arise because the Coriolis force – due to the Earth’s rotation – varies with ...

La Niña increased the chance of extreme rainfall in eastern Australia Weather systems driven by Rossby waves triggered the recent extreme rainfall The chance of heavy rain in eastern Australia ...

Some of the most important waves are called Kelvin waves and equatorial Rossby waves. Kelvin waves are centered around the equator, propagate to the east, and take between 2.5 and 17 days to ...

Unlike Earth, where Rossby waves dominate atmospheric circulation, on Mars, gravity waves take precedence. These waves, too small to be measured directly, must be estimated using indirect methods.

First, it disturbed the atmosphere in just the right way to set off an undulation in the jet stream — a river of very strong winds in the upper atmosphere — that atmospheric scientists call a Rossby ...
