This course is an introduction to primary concepts of geophysical wave movement in rotating, stratified, and rotating-stratified fluids. Topic begins with basic wave ideas of section and group velocity. It additionally covers the dynamics and kinematics of gravity waves with a concentrate on dispersion, power flux, preliminary worth issues, and so forth. Additionally addressed are topic basis used to check inside and inertial waves, Kelvin, Poincare, and Rossby waves in homogeneous and stratified fluids. Laplace tidal equations are utilized to equatorial waves. Different subjects embrace: resonant interactions, potential vorticity, wave-mean move interactions, and instability.
