A decrease in atmospheric pressure increases flatulences.
Details :
A lowering in external pressure induces a dilatation of bodily gases. To reach an equilibrium, it is necessary to pass gas now and then.
This phenomenon is mostly observed at high altitude (mountains e.g.). Jet pilots, who are concerned by this too as they experience sudden changes in atmospheric pressure, contributed to the study of this effect.

I note “don't eat beans at high altitude”.
