Abstract: | To describe the nonlinear propagation of electrostatic drift waves the generalized Hasegawa–Mima equation containing both vector Jacobian and scalar Korteweg–de Vries-type nonlinearities is obtained for electron-positron-ion plasmas. The drift waves are supposed to have arbitrary wavelengths as compared with the Larmour radius of plasma ions at the plasma electron temperature . Temperature inhomogeneity of electrons and positrons is taken into account. Spatial increase in the linear plasma-potential perturbations in the direction of density and temperature inhomogeneities is shown. Self-organization mechanism of large-scale drift solitary vortices is considered. It is shown that the existence of positrons in plasma enriches the class of solutions of the generalized Hasegawa–Mima equation. © 2009 American Institute of Physics |
