Scientists have found that internal variability can make one season twice as active as another, even when large-scale hurricane-shaping elements are unchanged. The research suggests that seasonal hurricane forecasts could be improved by conveying the amount of unavoidable uncertainty in the outlook.

More than 1,000 forecasters, researchers, and other professionals from around the globe will convene in Montréal on August 16–21 for a first-of-a-kind meeting aimed at pooling international thought on where weather prediction is headed. NCAR and UCAR participants are on tap to cover a wide range of promising developments.

A field project this June and July will study gravity waves, towering atmospheric features little-known to the public. Novel instruments to be deployed for the international DEEPWAVE project, based in New Zealand, will provide an unprecedented view of gravity waves, a major shaper of atmospheric variability at multiple heights.
