Detailed Description

Idealized Hurricane forcing source term Apply mesoscale tendency source term to drive the flow and match the hurricane cyclic/rotational forcing at large distances from the eye-wall. This implements the "Simple" method of George Bryan. Details can be found in: "A simple Method for Simulating Wind Profiles in the Boundary Layer of Tropical Cyclones. Bryant et al. Boundary-Layer Meteorol (2017) DOI 10.1007/s10546-016-0207-0
