NA0

matrix component that multiplies \(A_0\) to compute \(\tilde{\eta}\).

---

Description

Real valued property with dimensions \((j,kl)\) and no units.

Discussion

These are the row 3, column 2 components of the wave-vortex (S)orting matrix, referred to as the \(S\) matrix in Early, et al. (2021). The primary internal gravity wave and geostrophic solutions that exist for \(k^2+l^2>0, j>0\) are summarized in equation C4.

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

\[\textrm{NAm} \equiv 1\]

in the manuscript. In code this is computed with,

NA0 = ones(size(Kh));

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

NA0(:,:,1) = 0;

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

NA0(1,1,:) = 0;
