Abstract

Data from the MERRA-2 archive were used to study characteristics of the Northern Hemisphere’s middle atmosphere during the solar proton events of January 2005. It was found that the events were accompanied by sharp changes in zonal wind speed and temperature in the high-latitude atmosphere. The results obtained provide evidence of an intensification of the stratospheric polar vortex during the events, which was followed by a sharp weakening of the vortex and the development of a stratospheric warming.

2005年1月太阳质子事件期间北半球中层大气特征的变化

MERRA-2档案的数据被用来研究2005年1月太阳质子事件期间北半球中层大气的特征。研究发现，这些事件伴随着高纬度大气纬向风速和温度的急剧变化。结果表明，平流层极涡在事件期间增强，随后极涡急剧减弱，平流层变暖。
