(1) Formulate a hypothesis: what phase speed do you expect for a Kelvin wave? Why?
(2) Simulate a Kelvin wave using the model provided. You can either find the phase speed using a Hovmöller diagram, or track one of the peaks of the waves in the 3-dimensional numerical output of the simulation.
(3) Report the phase speed you found supported by relevant figures. Did the phase speed meet your expectation? Why/why not?
