A Statistical Study on DH CMEs and Its Geoeffectiveness
Figure 2
Distribution of duration of DH-type-II bursts for (a) nongeoeffective events and (b) geoeffective events and bandwidth of DH-type-II bursts for (c) nongeoeffective events and (d) geoeffective events. In the Figure the geoeffective events are shown in right side and the nongeoeffective events on left side.
