Scientific paper

The nature of plasma perturbations created by transverse ion heating in the auroral and polar region of the magnetosphere is investigated. The creation of the perturbations by transverse ion heating and their evolution are studied by solving a set of plasma transport equations along open flux tubes for geocentric altitudes not less than 9371 km/s. Both localized and extended heating events in space are considered. Both short- and long-duration heating events are studied as well. For localized heating, the perturbation in the density consists of a density cavity topped by a density bump. During the early stage the plasma in the bump is that expelled from the cavity by the mirror force. The flow velocity is enhanced over the entire perturbation. The dominant feature of the density perturbation produced by extended ion heating is the formation of a cavity expanding ever upward as long as the heating lasts. Inside the cavity and above it the perpendicular temperature and flow velocity are enhanced.
