Beta plane

The concept of a "Beta plane" is primarily used in geophysical fluid dynamics, particularly in the study of the atmosphere and ocean. It refers to a simplified model of the Earth's rotation that helps in understanding large-scale flows, such as ocean currents and atmospheric dynamics. ### Key Features of the Beta Plane: 1. **Curvature of the Earth**: The Earth is not flat, and its rotation results in varying Coriolis force depending on the latitude.
