Simultaneous observations of atmospheric vertical potential gradient from coastal Antarctic Stations Bharati and Maitri ...
Simultaneous dual station observations of the atmospheric electric potential gradient (PG) at Bharati and Maitri studied for the period 2014-2016, bring out a new regional diurnal pattern of fair-weather PG for the coastal Antarctic region, perhaps the ubiquitous characteristics of the PG for the co...

Simultaneous dual station observations of the atmospheric electric potential gradient (PG) at Bharati and Maitri studied for the period 2014-2016, bring out a new regional diurnal pattern of fair-weather PG for the coastal Antarctic region, perhaps the ubiquitous characteristics of the PG for the coastal Antarctic region. It is a broad minimum in the Carnegie-type PG variation. The surface wind distorts the fair-weather diurnal pattern of PG over Bharati more significantly than at Maitri. Katabatic wind effect over Bharati PG than Maitri PG is the sharper slope gradient of the ice sheet over Bharati than over Maitri as a consequence the katabatic wind streamlines drain over the Lambert glacier, located close to Bharati station. The wind speed significantly affects the Bipolar Air Ion Concentration (BAIC) by accumulation and dispersion. The concentration is maximum when the wind speed is minimum.
