N2 - Field experiments show that the poleward velocity of high-altitude weather balloons may, on rare occasions, be much higher than the observed poleward winds, while their eastward velocity is much slower than the observed eastward winds. Considering a simple physical model of horizontal particle's motion in the atmosphere, which includes a realistic model of the pressure field, it is shown that the existence of a nearly flat parabolic resonance in the model gives rise to such flights of balloons on the observed timescales even though the associated atmospheric pressure field does not support large poleward velocities.
