placeParticlesOnIsopycnal

places Lagrangian particles along a specified isopycnal

---

Declaration

 zIsopycnal = placeParticlesOnIsopycnal(x,y,z)

Parameters

• x array of particle x positions
• y array of particle y positions
• z array of z location of target isopycnal in the no-motion profile

Returns

• zIsopycnal particle depth

Discussion

Given particle position (x,y), zNoMotion is used to determine the target isopycnal using the no-motion density,

  targetRho = wvt.rhoFunction(zNoMotion);

and a minimization algorithm is used to find zIsopycnal such that

  zIsopycnal = rho(targetRho);

where rho is the current total density field of the fluid.

Note that the density is not necessarily monotonic, so the answer is not necessarily unique.
