Reconstructs \(w\) from \(A_-\).

These reconstruction coefficients map \(A_-\) onto the \(w\) state variable. In the historical notation of Early et al. (2021), they are the row 4, column 2 entries of \(S\) for the primary internal-gravity-wave and geostrophic solutions in equation C4.

For \(k^2+l^2>0, j>0\) this is written as,

\[\textrm{WAm} \equiv - i K h\]

in the manuscript. In code this is computed with,

WAm = -sqrt(-1)*Kh.*self.h;

There are no \(k^2+l^2>0, j=0\) wave solutions for a rigid lid,

WAm(:,:,1) = 0;

The inertial solutions occupy the \(k^2+l^2=0\) portion of the matrix,

WAm(1,1,:) = 0;
