◆ pv_operator()

subroutine pv_operator	(	real(kind=kind_real), dimension(nx,ny,2), intent(in)	x,
		real(kind=kind_real), dimension(nx,ny,2), intent(out)	pv,
		integer, intent(in)	nx,
		integer, intent(in)	ny,
		real(kind=kind_real), intent(in)	F1,
		real(kind=kind_real), intent(in)	F2,
		real(kind=kind_real), intent(in)	deltax,
		real(kind=kind_real), intent(in)	deltay
	)

Potential vorticity operator.

Applies the linear operator part of the PV calculation:

\begin{eqnarray*} q_1 &=& \nabla^2 \psi_1 - F_1 (\psi_1 -\psi_2 ) \\\\ q_2 &=& \nabla^2 \psi_2 - F_2 (\psi_2 -\psi_1 ) \end{eqnarray*}

(Note: The full potential vorticity calculation is done in calc_pv, and includes additional beta and orography terms.)

Parameters

[in]	nx	Zonal grid dimension
[in]	ny	Meridional grid dimension
[in]	x	Streamfunction
[out]	pv	Result of applying the operator to x
[in]	f1	Parameter in the PV operator
[in]	f2	Parameter in the PV operator
[in]	deltax	Zonal grid spacing (non-dimensional)
[in]	deltay	Meridional grid spacing (non-dimensional)
