I've attempted to show the air flow lines, overlaid on the "velocity" image (if that is what it is showing):

And here it is with just the flow lines:

As you can see the greatest velocity occurs where the air is being pushed aside at the greatest angle, and this is what gives it the greatest velocity. I think that the nose pushes the air up above the main part of the hood, and then the upper part of the windshield again pushes it up; creating another higher velocity zone.
