The magnetic field data and plasma parameters obtained by "Interball 1" in the morning sector of magnetospheric tail at a geocentric distance of about 10-25 Earth radii are analyzed. Wave properties are investigated using the spectral and wavelet analyses. The slow magnetosonic and Alfven wave coupling is studied. Vortical structures are found using the Poynting vector disturbances along the local magnetic field line. Association between the vortical structures and the compression waves of pc5, 6 type is found. The formation of vortical structures due to the development of nonlinear disturbances is discussed.
