notice how the lines occurs at 0.05 intervals, i dont think it is related to the grids
plotting code if this helps Y is a 401x401 matrix which corresponds to the height in the plot
x = 10:0.05:30;
z = 1:0.005:3;
[X,Z] = ndgrid(x,z);
mesh(X,Z,Y)
xlabel('x'),ylabel('z'),zlabel('height')
axis auto
xlim ([10 12])

How did you plot it in the first place? Maybe set 'EdgeColor' to 'none' (works in some functions like histogram). Or try
grid off

And for the first question "How did you plot it in the first place"??? Can you attach your Y data in a .mat file so we can try things ourselves with your data?
You DO know though that mesh() is supposed to give a wireframe surface, right? If you don't want that, try surf().
