add_incr()

subroutine, public mpas_state_mod::add_incr	(	class(mpas_fields), intent(inout)	self,
		class(mpas_fields), intent(in)	increment
	)

add increment to state

add_incr() adds "increment" to "state", such as state (containing analysis) = state (containing guess) + increment Here, we also update "theta", "rho", and "u" (edge-normal wind), which are close to MPAS prognostic variable. Intermediate 3D pressure is diagnosed with hydrostatic balance. While conversion to "theta" and "rho" uses full state variables, conversion to "u" from cell center winds uses their increment to reduce the smoothing effect.

Analytic Initialization for the MPAS Model.

analytic_IC() initializes the MPAS Field and State objects using one of several alternative idealized analytic models. This is intended to facilitate testing by eliminating the need to read in the initial state from a file and by providing exact expressions to test interpolations. This function is activated by setting the "analytic_init" field in the "initial" or "StateFile" section of the configuration file.

Initialization options that begin with "dcmip" refer to tests defined by the multi-institutional 2012 Dynamical Core Intercomparison Project and the associated Summer School, sponsored by NOAA, NSF, DOE, NCAR, and the University of Michigan.

Currently implemented options for analytic_init include:

• invent-state: Backward compatibility with original analytic init option
• dcmip-test-1-1: 3D deformational flow
• dcmip-test-1-2: 3D Hadley-like meridional circulation
• dcmip-test-3-1: Non-hydrostatic gravity wave
• dcmip-test-4-0: Baroclinic instability
