摘要
The ionosphere can be disturbed by the external energy sources. For example, there are ionospheric storms （ISs） which follow the interplanetary shock waves （ISWs） sweeping over the earth. It is not known what connection exists between parameters of ISs and ISWs because of the complexity in the coupling chain from interplanetary space to ionosphere. In order to probe the unknown connection, the correlative study is carried out in this note by using the data of ISWs obtained by space vehicles near the earth’s orbit and the materials about the ionospheric f<sub>0</sub>F<sub>2</sub> in Manzhouli during 1966—1976.
