If it feels as though it's sucked upward, the 'low pressure on top
of
the wing' model makes a lot of sense. If it feels like it's being
pushed upward, you might consider conservation of momentum models,
where the stream of air is being diverted downward by your hand, and
that old saw about for ever action there's an equal but opposite
reaction comes into play.

Hogwash warning.

The contribution of the top of the wing to airflow deflection (which
is considerable) is subject to conservation of momentum (energy,
whatever) just as is diversion by the bottom. EVERYTHING and every
diversion of flow is subject to conservation of energy.

There is NOT a low pressure Bernoulli model for what is taking place
on top of the wing and Newton related equal and opposite reaction
model for what is happening on the bottom. There is NO controversy,
except in the minds of the uninformed in places like newsgroups, as to
which model better describes lift. There is only an overall flow
pattern set up around the airfoil, every aspect of which is governed
by conservation of energy. Newton's laws and Bernoulli's theorems are
each just tools for explaining and predicting various aspects of what
is happening.

The endless Newton vs Bernoulli threads are as pointless as arguing
about whether hammers or saws are more important to the construction
of a house.
