When the throttle plate is closed, there is a big pressure difference between manifold vacuum and atmospheric pressure. When you snap the throttle, the pressure, RAPIDLY, equalizes .

( 1 ) This RAPID in-rush of air is the first rise.
( 2 ) Now, with the pressure equalized, the in-rush of air, drastically, slows down.
( 3 ) Then, as the RPM's rise, air flow rises, again.

When I was learning to use a scope I found it quite a good exercise first time I captured MAF on one channel and MAP on another.
