Abstract
Using Rossby wave equations, the dispersion equation is developed. The wave normal diagram for Rossby waves on a beta plane is a circle in wave number (k, l) space whose center is displaced along the negative X axis, and whose radius is less than this displacement, which means that phase propagation is entirely westward. The phase velocity diagram is a circle whose center is displaced along the negative X axis, the group velocity diagram is an ellipse whose center is displaced westward and whose major and minor axes give the maximum all the directions group speeds as function of the frequency and parameter Q.
