- Researchers are understanding more clearly how multiyear
cycles such as El Niño and La Niña and the Pacific Decadal Oscillation
influence tornado frequency. For example, when La Niña is transitioning
to El Niño during springtime, the odds of a major tornado
outbreak—especially in the Midwest and South—appear to be almost twice
as large as in neutral springs, according to a recent Journal of Climate paper led by Sang-Ki Lee (University of Miami/NOAA).
- The NOAA Climate Forecast System (CFS) now issues nine-month forecasts of U.S. circulation anomalies four times each day. This makes it a potential foundation for building weekly to seasonal tornado outlooks.
- High-resolution regional models that simulate thunderstorms directly—such as ARW, the NCAR-based Advanced Research Weather Research and Forecasting Model—can now be linked to larger-scale climate models..."
