| 摘 要： | A statistical study of the properties of ions (O , He and H ) measured by the Cluster-II in cusp region as a function of the solar wind dynamic pressure and geomagnetic index Kp respectively was made dur-ing the summer and fall of 2001-2003. The main results are that: (1) O ion density responds in a sig-nificant way to geomagnetic index Kp, and He ion density is not correlated with geomagnetic index Kp, both of them have a significant positive correlation with solar wind dynamic pressure; (2) H ion density is also observed to increase with solar wind dynamic pressure, and not correlated with geomagnetic index Kp. |
