Scientists from New York University in Abu Dhabi analyzed 25 years of data obtained from space and
For decades, theorists have speculatedthe existence of solar inertial waves, which are hydrodynamic waves found in rotating fluid bodies, says Chris Hanson, co-author of the study. — On Earth, inertial waves play an important role in shaping the weather. For example, they push cold polar air out of the Arctic into North America.”
The found inertial waves appear in the formvortices on the surface of the Sun and move at three times the speed of Rossby waves (the best-known inertial waves that occur in rotating fluids). Scientists note that Rossby waves move at the highest possible speed, explained by hydrodynamics.

The researchers hypothesized that such an increasethe speed of the waves they found can be caused by the influence of a magnetic field, gravity or convection currents. However, the results of modeling the impact of these factors contradict the data obtained by observing the Sun. Thus, the nature of new waves remains a mystery to scientists.
“We have yet to determine the source of these waves,since they, apparently, cannot be explained only by hydrodynamics and the influence of additional factors on it, Hanson notes. “The uncertain nature of these waves promises us the creation of new physics and a fresh look at the processes occurring inside the Sun and other stars.”
