Numerical Modeling of the Influence of Solar Activity on the Global Circulation in the Earth’s Mesosphere and Lower Thermosphere by Igor Mingalev, Victor Mingalev

“…The simulation results indicate that solar activity ought to influence considerably on the formation of global neutral wind system in the mesosphere and lower thermosphere. The influence is conditioned by the vertical transport of air from the lower thermosphere to the mesosphere and stratosphere. …”

The Northern and Southern Hemispheric Asymmetries of Mesospheric Ozone at High Latitudes During the January 2012 Solar Proton Events by Shiping Xiong, Jingyuan Li, Guanchun Wei, Jianyong Lu, Yufeng Tian, Xiaoping Zhang, Shuai Fu, Meng Sun, Zheng Li, Hua Zhang, Jingqi Cui, Shuwen Jiang, Chaolei Yang

“…Abstract Observations by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) and simulations by the Whole Atmosphere Community Climate Model‐eXtended (WACCM‐X) are used to analyze the impacts of the January 2012 solar proton events (SPEs) on mesospheric ozone at high latitudes. The mesospheric ozone at high latitudes decreased evidently with the increasing proton flux and ionization rates during SPEs. …”

The Possible Role of Turbopause on Sporadic‐E Layer Formation at Middle and Low Latitudes by Qiong Tang, Chen Zhou, Huixin Liu, Yi Liu, Jiaqi Zhao, Zhibin Yu, Zhengyu Zhao, Xueshang Feng

“…The theoretical modeling results show that metallic ions can effectively accumulate by the combined effect of the zonal and meridional winds in the mesosphere and the lower thermosphere region. Numerical simulation results also demonstrate that metallic ions can accumulate without wind shear at lower height (90–105 km) as a consequence of the MLT winds leading to the ion drifting downward. …”
