Dependence of distribution parameters of large-scale electric fields on Kp and AE indices of geomagnetic disturbance

Regression equations, which link potential drop ΔΦPC, kV with KP in polar cap and which are generalized in the form of ΔΦPC=20+15KP, are obtained on the basis of three groups of published data on measurements conducted using cosmic vehicles and incoherent scattering facility. Regression equation for ΔΦPC and AE is obtained using data of DE-2 CV: ΔΦPC=31.65±12.50 (AE/100). Usage of the large file-mean initial data of ΔΦRS values realized filtration and determined high, no lower, than 0.9, coefficients of correlation. Regression equations, which link P index of precipitation and invariant latitudes of convection lower boundary in the night and morning sectors with KP-index, are presented
