Waves like those controlling weather on Earth found on the Sun

New insights on the internal workings of the Sun. The lead researcher notes: “Solar Rossby waves are gigantic in size, with wavelengths comparable to the solar radius”. They have maximum amplitudes in the Sun’s equatorial regions.

A team of scientists led by the Max Planck Institute for Solar System Research (MPS) and the University of Göttingen has discovered new waves of vorticity on the Sun, reports Phys.org.

As described in today’s issue of Nature Astronomy, these Rossby waves propagate in the direction opposite to rotation, have lifetimes of several months, and maximum amplitudes at the Sun’s equator. For forty years scientists had speculated about the existence of such waves on the Sun, which should be present in every rotating fluid system.

Now, they have been unambiguously detected and characterized for the first time. The solar Rossby waves are close relatives of the Rossby waves known to occur in the…
