I believe you are referring to some very recently published research by Scott McIntosh's group about Rossby waves (see, for example, https://phys.org/news/201...space-weather.html). The Rossby wave in Earth's atmosphere helps circulate cold air from the poles to the equator and warm air from the equator to the poles. Theresearch postulates similarities between solar and terrestrial data. Analysis of terrestrial Rossby waves allows for long-term predictions of Earth weather (for example, how hot will the summer be). It could be that analysis of Rossby waves might allow us to predict how severe "space weather" might be over the next few weeks to months. To learn more about space weather, aurorae, and meteor showers look at this non-NASA website (but I know who produces it): http://spaceweather.com/
