| Abstract: | Effects of the magnetospheric ring current on nocturnal geomagnetic variation are analysed by means of Hibherd's method on the basis of horizontal component of geomagnetic field (H) at Beijing and Guangzhou observatories. A practical approach to approximate estimation of the intensity of the ring current is suggested, which can be used to monitor variation of the ring current and supplying useful information for short-term prediction of magnetic storms. |
