Forecasting Return Time of Extreme Precipitation by Large Deviation Theory

The Takeaway
Predicting extreme rainfall is notoriously difficult and usually relies on statistics from past weather events. This paper discovered a 'hidden connection'—a mathematical pattern called the Landau distribution, normally used in high-energy plasma physics, describes extreme rainfall better than anything else. In fact, it accurately predicts rainfall at 93% of locations across the globe. This means a tool designed for stars and fusion reactors is actually the 'correct' way to predict catastrophic floods on Earth. For regular people, this could lead to much more accurate early-warning systems, potentially saving lives by predicting 'once-in-a-century' storms using the same logic we use to study the sun.
From the abstract
Forecasting extreme precipitation is essential yet challenging due to its rarity and complexity. We develop a large deviation framework to estimate the return times of extreme precipitation events. We first find that the Landau distribution, originally introduced in plasma physics, accurately captures extreme precipitation at approximately 93% of global locations, outperforming conventional extreme value distributions with 76% matched locations under the same accuracy criterion.
