| Abstract: | In this paper, using geomagnetic Z-component data in Mengcheng Seismic Station nearly 20 years, we analyzed the amplitude and low-point time of magnetically quiet day and the am- plitude of magnetically disturbed day＇s annual variation and long-term changes. The results showed that the characteristic of daily variation of Z-component obviously, so we can summarize some basic characteristics of changes in the geomagnetic Z-component. In the paper, certain value for reference to recognition interference and abnormal of the geomagnetic field is presented. |
| Keywords: | Z-component magnetically quiet day magnetically disturbed day low-point time |
