The 2014-2016 geoelectric field observation data from the Changli station, Hebei province, are analyzed in this study. Results indicate that the daily variation in NS components of the geoelectric field exhibits double peaks and a single valley, similar to that of geomagnetic fields. In contrast, the daily variation in EW components of the geoelectric field has double peaks and double valleys with obvious, semi-diurnal waves, which are affected by the earth tide. The geoelectric field at Changli station is a tidal geoelectric field.
