Is it possible to predict large-scale seasonal weather patterns? This is one of the research questions that motivates scientists at the National Science Foundation (NSF). This special report from the NSF looks into how atmospheric oscillations from the El Nino-Southern Oscillation (ENSO) in the tropics to the Arctic Oscillation (AO) play a "significant part in controlling the weather on a seasonal time scale." This report was written by Cheryl Dybas, and it contains four sections, along with an area with classroom resources. The sections cover new real-time weather forecasts ("A New and Better Way"), the creation of a more effective prediction model ("New Seasonal Forecast Model"), and a demonstration of the new model ("Model Accuracy Demonstrated"). The site is rounded out by the classroom resources which are designed to be used with the charts, maps, and interactive animations featured in the rest of the site.
