Rossby waves and polar spots in rapidly rotating stars: Implications for stellar wind evolution
magnetic fi eld – Stars: activity – Stars: starspots – Stars: oscillations – Physical data and processes: Magnetohydrodynamics
2011/10/10
Rapidly rotating stars show short-period oscillations in magnetic activity and polar appearance of starspots. The aim of this paper is to study large-scale shallow water waves in the tachoclines of ra...
Nonlinear interaction between long inertio-gravity and rossby waves
Nonlinear interaction long inertio-gravity rossby waves
2009/11/16
The equations describing the interaction of long inertio-gravity (IG) waves with the Rossby waves are derived. Due to remarkable cancellations, the interaction is shown to be anomalously weak. As a re...

Barotropic Rossby Waves Zonal Current Lateral Viscosity
2009/3/24
The behavior of a barotropic Rossby wave in a zonal current is studied theoretically using a beta-plane ocean of constant depth in which the current depends only on latitude. The wave may be reflected...

2009/3/7
We know that long-period (>1 day) and long-wavelength (>100 km) topographical Rossby waves can be generated by a wind acting directly on a continental shelf (Adams and Buchwald, 1969). Here we examine...
