Ionospheric cusp flows pulsed by solar wind Alfvén waves
Pulsed ionospheric flows (PIFs) in the cusp footprint have been observed by the SuperDARN radars with periods between a few minutes and several tens of minutes. PIFs are believed to be a consequence of the interplanetary magnetic field (IMF) reconnection with the magnetospheric magnetic field on the dayside magnetopause, ionospheric signatures of flux transfer events (FTEs). The quasiperiodic P...
متن کاملSolar wind Alfvén waves: a source of pulsed ionospheric convection and atmospheric gravity waves
A case study of medium-scale travelling ionospheric disturbances (TIDs) that are correlated with solar wind Alfvén waves is presented. The HF radar groundscatter signatures of TIDs caused by atmospheric gravity waves with periods of 20–40 min are traced to a source at high latitudes, namely pulsed ionospheric flows (PIFs) due to bursts in the convection electric field and/or the associated iono...
متن کاملOrigin of long - period Alfvén waves in the solar wind
We suggest that the observed long-period Alfvén waves in the solar wind may be generated in the solar interior due to the pulsation of the Sun in the fundamental radial mode. The period of this pulsation is about 1 hour. The pulsation causes a periodical variation of density and large-scale magnetic field, this affecting the Alfvén speed in the solar interior. Consequently the Alfvén waves with...

متن کاملAlfvén waves in the lower solar atmosphere.
The flow of energy through the solar atmosphere and the heating of the Sun's outer regions are still not understood. Here, we report the detection of oscillatory phenomena associated with a large bright-point group that is 430,000 square kilometers in area and located near the solar disk center. Wavelet analysis reveals full-width half-maximum oscillations with periodicities ranging from 126 to...
