Classified prediction of geomagnetic disturbance caused by coronal mass ejection;

The relationships between the coronal mass ejections (CMEs), interplane tary disturbances and geomagnetic storms are studied, involving the solar source distribution of geoeffective halo CMEs, the periodicity of CMEs, X-ray flares a nd geomagnetic disturbances, the threshold of interplanetary parameters in causi ng geomagnetic storms, etc.

THE MONITOR OF THE CME IN MARCH 1991 BY COSMIC RAYS;

With the background structure,two tube models containing spiral magnetic field lines with a small length-scale can move in the computational domain step by step,interact afterward and trigger a Coronal Mass Ejection(CME)finally.

The influence of a streamer background with nested close magnetic structures on the properties of CME initiated from its bottom is investigated in a solar meridian plane.

Comparison of space weather effects of two major coronal mass ejections in late 2003;

Statistical analyses of the correlation events between the type Iff radio bursts and Coronal Mass Ejections (CMEs) during 23rd cycle are presented, radio data were observed with the 20～420 MHz at the Radio Spectrograph Culgoora Solar Observatory in Australia.

It is shown in this paper that the solar radio bursts originate not only from flares but also from coronal mass ejections (CMEs) or CME flare combinations, based on the data of recent space and ground besed solar observations.
