Abstract
A pair of nonlinear equations for dust-acoustic gravity waves in a non uniform multicomponent dusty gas is obtained. The possibility of dust- acoustic gravity wave instability and the formation of vortices at the marginal stability point are discussed. The results can have relevanc e to the generation of waves and coherent nonlinear structures in low- temperature ionospheric as well as in astrophysical dusty plasmas.
