- 論文の詳細を見る
Electric fields were measured with three pairs of conducting plate antennas on board a balloon which was launched from Stamsund (L=6.0), Norway at 1909 UT on March 20,1982. During the balloon flight at the ceiling altitude of 32km, two sequential substorms occurred. The direction of horizontal electric field change can be explained as an electric field behavior near the Harang discontinuity, a boundary between the eastward and westward auroral electrojet currents. The vertical electric field and current increased greatly when the balloon transversed over the mountainous area. This increase can be interpreted by a mountain effect on the stratospheric electric field. The conductivity obtained by the combination of the vertical electric field and current is estimated (1-2)×(10)^<-11>S/m and it reconfirms the value of conductivity in the polar stratosphere.
