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.

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.

Some of the world’s most intense thunderstorms, associated with destructive impacts like high winds, large hail, and flash floods, occur in the tropical and subtropical regions, including parts of the southern U.S. However, scientists have been uncertain about how such storms will respond in the context of warming temperatures.

Two new datasets, funded in part by NOAA Research’s Modeling, Analysis, Predictions, and Projections (MAPP) Program, now provide easy public access to 60 terabytes of climate forecasts containing predictions of rainfall, temperature, winds and other variables at the subseasonal level (two weeks to two months ahead).
