By global geomagnetic observation data the variations of intensity and dynamics of auroral electrojets, low-latitude disturbances at latitudes ~10-55°, SYM-H and studied. It is shown that positive values of SYM-H and Dst or the decrease of their negative values correspond to the growth period of Pd. The enhancement of magnetic field depression at latitudes Ф'~10-30° with the maximum ∆H in the evening sector is observed at negative values of IMF Bz and is accompanied by the enhancement of auroral electrojets in all temporal sectors and their southward shift. The maximum values of Dst ~-400 nT correspondent to the most intensity of western (eastern) electrojet in the midnight (evening) sector with a current center at the lowest latitudes. The possible sources of Dst and SYM-H variations are discussed.
