Identification of the polar cap boundaries has been made on the basis of specific features of precipitating ions. The data on the polar cap boundary location obtained for different geophysical conditions have been used to derive the statistical relationship between the polar cap diameter and <jats:italic>PC</jats:italic> index. The analysis has shown an approximately linear relationship between the polar cap diameter and the <jats:italic>PC</jats:italic> index for values <jats:italic>PC</jats:italic> < 3, the diameter tending to be asymptote when the <jats:italic>PC</jats:italic> index reaches large positive values. Cross polar cap voltage derived from EXOS D data is in good correlation with interplanetary quantities including the interplanetary magnetic field (IMF) southward component. The best correlation is obtained for the merging electric field υ<jats:italic>B<jats:sub>T</jats:sub></jats:italic> sin<jats:sup>2</jats:sup> θ/2, with a coefficient of correlation higher than 0.82. Almost the same correlation is observed between polar cap voltage and <jats:italic>PC</jats:italic> index. The effect of “saturation” is not traced in the voltage dependencies on the <jats:italic>PC</jats:italic> index and interplanetary quantities up to values <jats:italic>B<jats:sub>T</jats:sub></jats:italic> ≤ 10 nT.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380290617391255942","@type":"Researcher","foaf:name":[{"@value":"O.
