We investigate streaming instability using two-fluid approximation (neutral gas and dust) in global, stratified protoplanetary disk, with the help of PIERNIK code. We compare amplification rate of the eigen-mode in numerical simulations, with the corresponding growth resulting from the linear stability analysis of full system of Euler's equation in cylindrical coordinates, including aerodynamical drag. We find that the growth rate of streaming instability excited modes coincides with the growth rate resulting from linear stability analysis.
