Auroras are natural light displays that occur in the Earth's atmosphere, primarily near the polar regions. They are caused by interactions between charged particles from the sun (solar wind) and atoms or molecules in Earth's upper atmosphere.
congrats on reading the definition of Auroras. now let's actually learn it.
Magnetosphere: The magnetosphere plays a crucial role in aurora formation by trapping and guiding charged particles from solar wind towards Earth's poles.
Ionosphere: The ionosphere is a region of Earth's upper atmosphere where atoms and molecules become ionized due to high-energy radiation from the sun. It is involved in generating auroras.
Polar vortex: A polar vortex is a large-scale cyclonic circulation pattern that forms near Earth's poles. It can influence atmospheric conditions and affect aurora visibility.
