Abstract:
While Yi, Reid, Xue, Younger, Spargo, et al. (2017, http://doi:10.1002/2017JA024446) described
the observational results showing solar wind high‐speed stream (HSS) impacts on the mesosphere over
Antarctica, the specific physical mechanism behind them was not discussed. We discussed here how
magnetospheric wave‐particle interactions and energetic ~20‐ to 50‐keV electron precipitation into the
auroral zone atmosphere (diffuse auroras) during HSS intervals can cause the observed effects in
the mesosphere.
