It makes sense that there would be better strategies for simulation than gridding Navier-Stokes (the regularities in weather phenomena show that the space of likely possibilities isn't evenly distributed throughout the space that values on an evenly spaced lattice represent) but it's probably too complicated to come up with those schemes manually. If I had to guess what the model is "doing," (as opposed, say, to compensating for undiscovered problems with data acquisition) that would be it.
