Rossby waves in astrophysics
Rossby waves are a pervasive feature of the large-scale motions of the Earth's atmosphere
and oceans. These waves (also known as planetary waves and r-modes) also play an …

Magnetic Rossby waves in the solar tachocline and Rieger-type periodicities
Apart from the eleven-year solar cycle, another periodicity around 155–160 days was
discovered during solar cycle 21 in high-energy solar flares, and its presence in sunspot …

Quasi-biennial oscillations in the solar tachocline caused by magnetic Rossby wave instabilities
Quasi-biennial oscillations (QBOs) are frequently observed in solar activity indices.
However, no clear physical mechanism for the observed variations has been suggested so …

Space weather challenge and forecasting implications of Rossby waves
M Dikpati, SW McIntosh - Space Weather, 2020 - Wiley Online Library
Rossby waves arise in thin layers within fluid regions of stars and planets. These global
wave‐like patterns occur due to the variation in Coriolis forces with latitude. In the past …

On the connection between Rieger-type and magneto-Rossby waves driving the frequency of the large solar eruptions during solar cycles 19–25
Global solar activity variation mainly occurs over about an 11 yr cycle. However, both longer
and shorter periodicities than the solar cycle are also present in many different solar activity …
