[edit] Correct expression for the Rossby parameter
Hi, as defined in a number of textbooks including Kundu and Cohen's Fluid Mechanics (3E, pp.588, 2004), the Coriolis parameter should have the radius of Earth "a" in the denominator. See here:

Another reference is Ch.7 of the notes from an MIT class in GFD:

Moreover, the definition of beta is beta = df/dy, so if we have the radius in the numerator the expression is dimensionally inconsistent.
