Effects of the Horizontal Component of the Earth’s Rotation on Rossby Waves

Zhao Qiang and Liu Shikuo (Department of Atmospheric Sciences, School of Physics, Peking University, Beijing 100871)  
A horizontal component of the earth’s rotation is included in a set of linearized β-plane equations, which have a constant horizontal component of the Coriolis parameter, while the vertical component varies with latitude. This feature of the equations enables the vorticity and angular momentum principles to hold in their usual form. The influence of the f H=2Ωcosφ effect on Rossby waves is investigated. The results show that the f H effect can be important if the perturbations are function of the latitude. f H has clear effects on the frequencies of the Rossby waves. We also find that when the perturbations are independent of latitude, the f H effect disappears.
