Planet-sized 'waves' spotted in the Sun's atmosphere

Planet-sized 'waves' spotted in the Sun's atmosphere : Nature News & Comment: 

Rossby waves were discovered in Earth’s atmosphere in the late 1930s. Driven by a planet's rotation, they’ve been seen in the atmospheres of other planets, as well as in Earth’s oceans. In theory, these waves can form in any rotating fluid, says Scott McIntosh, a solar physicist at the National Center for Atmospheric Research in Boulder, Colorado and lead study author.
Researchers have long sought evidence of Rossby waves on the Sun, he says. And an enhanced understanding of these features and their movements could help scientists to better predict the formation of sunspots and the eruption of solar flares.
