Solar cycle evolution of active regions and coronal holes From an analysis of the 10 IGSs that occurred between 1978 and 1979, combining interplanetary scintillation (IPS) tracking

The question of generation mechanisms for the travelling convection vortices (TCV) signatures which are closely related to the magnetic impulsive events observed, most often, in

This event is a very good example of an appearance of a strong westward electrojet in the evening sector at all EISCAT magnetometer cross stations. The maximum of the negative

Therefore they account not only for the effects on the translational temperature of internal energy variation of the interacting particle (Morse, 1964; McCormack, 1968) but also for

storm with gradual commencement at about 01:00 UT was observed on 31 March 2001. In this paper, we present and discuss salient features from the ionospheric sounding mea-

4 it appears that the error in the e€ective pointing angle arising from the aspect sensitivity of echoes observed at a nominal zenith angle of 6° is largely responsible

A few of the difficulties in accurately modelling high-latitude electron densities with a large-scale numer- ical model of the thermosphere and ionosphere are ad- dressed by

For T=360 days most of the energy of the incoming equatorial wave is expected to be re¯ected at the meridional boundary as westward Rossby waves and, as already discussed, these
