Rossby waves are also known as planetary waves and giant meanders in ocean currents. They play an important role in ocean circulation and the transport of energy over vast distances and affect the planet’s climate.

The scientists managed to identify points where energy transfer stops and the trajectories of water movement change. The researchers also discovered an asymmetry in the dynamics of wave processes originating from western and eastern coastal currents. According to Tatyana Belonenko, Professor at SPbU, waves originating from eastern currents are approximately ten times longer than those from western currents.

As part of the research, the scientists used comprehensive mathematical models and computer simulations.

The findings change the understanding of how energy is transported in the ocean. Understanding the new mechanism of Rossby wave propagation could improve the accuracy of predicting the movement of seawater.
