Abstract The coupling process between solar wind‐magnetosphere‐ionosphere is an important physical 14 mechanism for the delineating concept of the magnetosphere‐ionosphere system. In this work, we have studied the polar cap potential (PCV) and merging electric field ( E m ) during three different supersubstorm (SSS) events. We have also studied the roles of polar cap index and auroral electrojet ( AE ) indices to observe polar cap activity during SSSs. To substantiate results, wavelet transform and cross‐correlation techniques are used. We checked the cross correlation of PCV with AE , SYM‐H , B z , X , Y , and E y individually. Positive good correlation of PCV with AE and SYM‐H is obtained. Observing and obtaining these results, PCV shows the significant effects during geomagnetic activity (SSSs) generated by geoeffective solar wind parameters.
