Abstract

The equations of motion that govern atmospheric (and also oceanic) flows are based on the theory of fluid mechanics comprising the Euler and/or Navier Stokes equations which model conservation of mass, momentum, and energy [27, 11] of a Newtonian fluid such as air and water. The so-known hydrostatic primitive equations are derived from these basic laws of physics after some major simplifications or approximations taking into account the particular topology of planetary flows [61, 216, 166].

\(L_e=\sqrt {2c/\beta }\), in some textbooks.

Consider the two cases when ω << 1 and when ω >> 1 separately to simplify the dispersion relation to approximately \( - k^2 - \frac {k}{\omega } = 2n+1\) and ω 2 − k 2 = 2n + 1, respectively.

These numerical solutions will be utilized later in this book when the multicloud model is used as a cumulus parameterization in a climate model.
