Large-scale planetary waves found on the sun

March 27 (UPI) -- Scientists at the National Center for Atmospheric Research have discovered Rossby waves on the sun. The large-scale planetary waves were first discovered on Earth.

On Earth, Rossby waves are correlated with local weather events. On the sun, scientists suggest the waves could influence solar activity and related phenomena, like sunspots and solar flares.

"The discovery of magnetized Rossby waves on the Sun offers the tantalizing possibility that we can predict space weather much further in advance," lead researcher Scott McIntosh said in a news release.

Rossby wave patterns are unique to rotating fluids, like the atmosphere and the ocean. The sun's upper layers are mostly plasma and rotate. Scientists have previously hypothesized that the sun could host Rossby waves, but observing wave patterns on the sun is difficult.
