Responses of Nitrogen Oxide to High-Speed SolarWind Stream in the Polar Middle Atmosphere

Abstract

Energetic electron precipitation (EEP) lead to production and subsequent transport of odd nitrogen, NOx = NO + NO2, from the mesosphere and lower thermosphere (MLT) into the stratosphere. They may affect the chemical compositions in the mesosphere and lower thermosphere region and can is significantly contributed to catalytic ozone destruction in stratosphere. The physical characteristics of high-speed solar wind streams are closely related to variations in space environments including the Earth's magnetosphere and the upper and lower atmospheres. In this study, we simulated atmospheric effect during high-speed solar wind stream with the Whole Atmosphere Community Climate Model using Specified Dynamics (SD-WACCM) and compared to satellite measurements.
