This always confuses me from a physics perspective. Upon touchdown, what is the effect of the wind on a large airplane/airliner (Boeing 737 and above)? Below are three cases I put together to make it easier to explain my confusion:

No decrab, the wind acts on the tall fin yawing to plane further into the wind at touchdown, and the pilot counters this by pushing the rudder downwind ([video][2]).

The pilot decrabs, the same effect upon touchdown, but here the correction is rudder upwind initially ([video][4]).

What I normally read: the wind pushes the aircraft, and the correction is rudder upwind. This [AOPA article][6] for instance, shows a drawing with the wind force pushing a [small-er] plane downwind.

Apologies if I butchered the crosswind landings.
