Vellante, U. Villante] Summary: Past observations and present models of the solar-wind controlled dayside Pc 3-Pc 4 pulsations are reviewed. A year-long comparison between solar-wind parameters obtained from IMP-8 and micropulsation measurements made at L'Aquila is presented. This study shows that at low latitudes the relationship between the two phenomena is more clear than at high latitudes. In particular, in agreement with the upstream-wave source mechanism, different frequency regimes of pulsations can be related to different regions of the high-velocity streams. Some examples of spectacular wave trains, with unusual amplitude and period, occurred during the strong geomagnetic storm of March 13, 1989 are also presented.
