摘要

The first Resolute incoherent scatter radar observations of the polar ionospheric F region show the fine control of the ionospheric plasma density and flow (electric field) by the solar wind interplanetary magnetic field (IMF). A summary of 8 days of observations is presented and 10 IMF B_z southward turning events during this period are analyzed in terms of the time delay of plasma density enhancements and ionospheric convection intensification with respect to the timing of B_z southward turning. We find that N_e enhancements are strongly tied to strong (?5 nT) IMF B _z southward turnings; arrive 25-75 mins (depending on MLT) after the IMF pulse arrives at the bowshock nose; last as long as B_z stays southward; contain as small as ～25 km horizontal substructures; are altitudinally smooth, a characteristic of a solar produced plasma. The most predictable response of ionospheric convection is anti-sunward flow intensification on average ～25 mins after B_z southward change.
