| Abstract: | The causes of the formation of neutral gas temperature and density equatorial minimums on the dayside, recently detected from
satellite measurements, have been studied based on a global numerical model of the Earth’s upper atmosphere (UAM). The performed
numerical experiments made it possible to conclude that these minimums are not related to the magnetospheric sources of energy
and momentum and electric fields of the dynamo origin. It has been indicated that the absorbed solar ionizing radiation and
rotation of the Earth are responsible for the formation of the neutral gas temperature and density equatorial minimums on
the dayside. |
