- Аннотация: Scintillation data recorded at the polar cap station Barentsburg are shown to occasionally exhibit two and more peaks in the latitudinal profiles of the amplitude dispersion. Comparison with concurrent SuperDARN radar convection maps indicates that multiple peaks occur when Barentsburg is located within the area of strong changes in the plasma flow direction. When parameters of the ionospheric irregularities are inferred from the scintillation data, the orientation of the irregularity anisotropy in a plane perpendicular to the magnetic field is found to coincide well with the ExB flow direction, individually for each peak of the scintillation data. The differences were found to be mostly less than 200 for a data set comprised of 104 events. Conclusion is made that analysis of scintillation data allows one to infer the direction of plasma flow with certain degree of detail.
