Abstract

Data from the DMSP F6 and F7 satellites are used to show that during the magnetic calm the ion pressure in the region of the ionospheric projection of the low-latitude boundary layer does not depend on the B_z component of the interplanetary magnetic field but grows rapidly along with the dynamic pressure of the solar wind. A local increase in ion pressure in the midday sector is detected, and its possible manifestation in the intensity of high-latitude dayside auroras is discussed.

白天低纬边界层降水区的离子压力

摘要

来自DMSP F6和F7卫星的数据用于表明，在磁平静期间，低纬度边界层电离层投影区域中的离子压力不取决于行星际磁场的B _z分量，而是迅速增长以及太阳风的动态压力。检测到中午部分离子压力的局部升高，并讨论了其在高纬度日间极光强度中的可能表现。
