The acceleration and deceleration of the shear layer mode coherent structures in the initial shear layers of two initially laminar subsonic circular air jets were measured by a novel method employing three hot-wires and the structure capturing scheme of the conditional sampling technique. Several modes of pairing, some of them axisymmetric and others involving tilted flow structures, were established and confirmed by flow visualization.
