addMeanDensityAnomaly

Add a mean-density anomaly to the existing fluid state.

Declaration

 addMeanDensityAnomaly(eta)

Parameters

• eta function handle that takes a single argument, eta(Z)

Discussion

The supplied horizontally uniform isopycnal displacement is projected onto the internal mean-density-anomaly modes and added to their A0 coefficients.

eta = @(z) 10*sin(pi*(z+wvt.Lz)/wvt.Lz);
wvt.addMeanDensityAnomaly(eta);

It is important to note that because the WVTransform de-aliases by default, you will not likely get exactly the same function out that you put in. The high-modes are removed.
