Abstract:We use static daily superposition and the FFT spectrum analysis method to analyze month by month observation data from the Hongchiba geoelectric field, and compare the results with the Wushan establishment of geomagnetic observation data. We calculate the induced electric field in Hongchiba site during the storm, contrast this with observed data, and analyze the characteristics of the geoelectric storm. The results show that: as the month changes, the phase of static daily curve changes. The diurnal variation of the electric field at 1, 2, 11, and 12 months is significantly smaller than at the other months. The periodic component of the geoelectric field is the same as the geomagnetic field. Comparison of periodic components shows that the changes of the spectral values of the different periodic components of the geomagnetic field are in agreement with the geomagnetic D components. The geoelectric storm in a certain direction is related to the magnitude of the magnetic storm in the vertical direction; the geoelectric storm in Hongchiba site is related to the electrical structure of the area; there is a linear relationship between the observed geoelectric storm and the calculated value of geomagnetic induced current; and the relationship of geoelectric storm and magnetic index K is index.
