  • Description:
    "This note discusses the basic steps used to construct finite difference forms for mass convergence in spherical coordinates for the NMC hurricane model. The original motivation behind this approach was the observation in an axial symmetric prototype of gravity wave generation at the storm center. These modes of horizontal scales around 4Ax, seemed most directly linked to spurious, central pressure changes and lack of exact mass conservation inherent in an early differencing scheme derived from semimomentum differencing concepts"--Page 1.
