The 20 fair -weather days average diurnal variation curve of the atmospheric electric field is single periodic with the maximum at 1300 GMT, and the minimum at 0100 GMT. It also shows a secondary but distinct maximum at 1900 GMT. The difference between the diurnal variation curve observed at Maitri and the universal varition curve observed at oceans and at the south pole is discussed with refrence to the validity of the classical global electric circuit. The electric conductivity does not show much change during a day either at Maitri or over open ocean. However, the conductivity has the minimum value at around 30?S the value of conductivity keeps increasing southward of 30?S upto 70?S and northward upto 10?S. The measurements of the electric field and conductivity of both polarities made during our stay at Maitri (70? 46,S, 11? 44,E), Antarctica and along the cruise track.
