Abstract Influence of small-scale turbulence on cloud droplets spatial distribution was analyzed by examination of motion of inertial droplets in a simple model of a vortex tube aligned at arbitrary angle to gravity force. Both analytical calculations and numerical simulations demonstrated characteristic features of the motion such as equillibrium points, limit cycles and stationary orbits, for which conditions of existence were calculated. Simulations of motion of polydispersed droplets illustrate sorting effects of a vortex tube
