In order to understand the global magnetospheric responses to solar wind changes and to investigate the transfer (or propagation) processes and latitudinal structures of magnetospheric disturbances, coordinated ground-based observations along the 210° magnetic meridian (MM) are being conducted by the Solar-Terrestrial Environment Laboratory, Nagoya University in cooperation with 27 organizations in Australia, Indonesia, Japan, Papua New Guinea, the Philippines, Russia, Taiwan, and the United States (Yumoto et al., 1992). In this paper, we review the initial results obtained from the 210° MM project; (1) a northern and southern hemisphere asymmetry for sudden commencements (sc) and sudden impulses (si), (2) low-latitude aurorae, (3) cavity-like and field line Pc 3-4 resonances stimulated by sc and si, (4) peculiarities of Pc 3 at low latitudes, and (5) the latitudinal profile of Pi 2.
