A pattern of convection is calculated for a magnetospheric model with open magnetic field lines going from the polar cap to the solar wind. A uniform anti-sunward flow at the open field lines is assumed as a source of convection. A layer with finite parallel conductivity is situated below the source. A decrease of the parallel conductivity gives rise to the following consequences: (1) The centers of convective vortices are not located at the boundary of the open field line area. They are shifted into this area, and (2) narrow intense convective sunward streams arise above the finite parallel conductivity layer at the dawn and dusk boundaries of the closed field line area. The characteristic width of the streams is about 10 km. The electric field in the streams is several hundred millivolts per meter. Small-scale (approximately 10 km) variations of field-aligned currents and of transverse magnetic disturbances with magnitude of approximately 100 nT are connected with the streams.
