After Using the Two Approximations
q Upper layer
qLower layer
η
h
•After the
approximations, there is no h in the two
continuity equation è They can be combined to become one equation.
•The two momentum
equations can also be combined into one single equation without h.
•At the end, the
continuity and momentum equations for the upper and lower layers can be combined to solve for the dispersive
relation for the baroclinic mode
of the gravity wave.
