Two sets of experiments studying the behavior of discharges that follow three-dimensional paths are described. The buoyant discharges are released horizontally at angles of 45° and 90° to the ambient flow. A dual-camera light-attenuation system is used to observe the flow. In contrast to a previous study the formation of double peak distributions is clearly evident for both discharge configurations, suggesting that the formation of a line vortex pair in the strongly-advected region of these flows is particularly sensitive to the initial conditions. In addition mean integrated concentrations profiles do not demonstrate the self-similar behavior that is typically assumed when modeling such flows.
