A new study says that teleconnections with certain phases of a recurring tropical rainfall pattern could extend predictions up to 20-25 days in advance. The authors’ findings provide guidance on which tropical conditions might lead to improved forecasts beyond our current capability – and more time to prepare for extreme events.

New line of information could help predict the storms’ future strength
A new study has found that seemingly trivial vibrations in the earth's surface can actually encode the power of hurricanes moving over ocean waters. The findings may make it possible to estimate the strength of past hurricanes, to reveal long term changes in the severity and frequency of these storms, and help scientists understand potential future changes.

“Flash drought” has become a popular term in the media, but the debate of what a flash drought really is has caused confusion that affects scientists’ ability to detect their onset, monitor their development, and understand how they evolve.

In many parts of North America, a fluctuating air-pressure pattern that enhances or blocks the storm-steering jet stream, called the Arctic Oscillation (AO), explains more variability in the weather than a primary influencer called the El Niño-Southern Oscillation (ENSO). However, the AO’s prediction skill has been known to be limited, until now.

Seven leading U.S. academic institutions recently released announcements about their new NOAA Research awards for cutting-edge projects to tackle coastal flooding, changing marine resources and drought. The releases highlight the importance of the federal funding, received from the NOAA Research Modeling, Analysis, Predictions, and Projections (MAPP) Program, for the universities and NOAA’s services advancement, as well as the potential significant societal and economic impacts of their new projects.
