Left and middle: simulated kinematics the height of rain blobs as a function of plane-of-the sky projected speed for a range of transverse oscillations amplitudes for a circular loop of length 70 Mm. Kinematic tracks for different amplitudes are represented by different colours. The green area represents the sub-ballistic regime. Right: effective acceleration as defined by Eq. (30) as a function of oscillation displacement amplitude. The effective gravity and critical displacement amplitude are highlighted. The solid curve is a best power-law fit within the constraints that it is equal to ⟨ g_{⊙ eff} ⟩ for a = 0 and 0 for a = a_crit.
