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 ...

“Solar Rossby waves have very small amplitudes and periods of several ... That these waves are only seen in the equatorial regions is completely unexpected”, Gizon explains. The vorticity patterns are ...

Equatorial Kelvin waves, which are responsible for the El Nino-Southern Oscillation, travel from West to East. Another type of equatorial wave--Rossby waves--move in the opposite direction.

These equations produce waves trapped close to the equator, always compelled to travel eastward, which are known as equatorial Kelvin and mixed Rossby-gravity (Yanai) waves. Other such waves also ...

That these waves are only seen in the equatorial regions is completely unexpected", Gizon added. "Solar Rossby waves are gigantic in size, with wavelengths comparable to the solar radius." Related: ...

That’s what happened to Texas last week: One of those Rossby waves brought cold Arctic air all the way south – and then stuck for a while. The jet stream itself didn’t stop.

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 ...

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 ...
