Satellite Observations of the Influence of Energetic Electron Precipitation on the Mesosphere and Stratosphere in the Northern Hemisphere [PDF]

Journal of Geophysical Research D: Atmospheres
The Earth’s atmosphere is influenced by energetic electrons coming from the magnetosphere. This energetic electron precipitation (EEP) is energized by the solar wind and directly affects in the high-latitude mesosphere and lower thermosphere (MLT).

Impact of the northern polar vortex and geomagnetic activity on solar radiation at surface and solar power production in Europe

Environmental Research Letters
Energy production by solar panels depends directly on the amount of incoming solar radiation at the surface. During winter, the weather in Europe is strongly influenced by the polar vortex, a westerly wind system circulating around the polar region in ...
