article_snippet.sent: Geomagnetic storms are more disruptive now than in the past because of our greater dependence on technical systems that can be affected by electric currents.
article_snippet.sent: And according to this new research, when the 11-year cycle combines with the two-year cycle, the solar storms that pummel Earth's atmosphere can be amplified.
article_snippet.sent: The study, published this week in Nature Communications, could help lead to better predictions of massive geomagnetic storms in Earth's outer atmosphere that sometimes disrupt satellite operations, communications, power grids and other technologies.
