MIT scientists unveil an AI model that doubles forecast accuracy at 2-6 weeks
MIT researchers Judah Cohen and Lester Mackey published in Nature an AI-based weather prediction model with post-processing that learns from its errors by comparing them with historical data. In the subseasonal range of 2 to 6 weeks, known as the "desert of predictability", overall forecast accuracy doubled compared with current models. The results could be useful for farmers and energy providers, and for predicting extreme events such as floods or cold waves.
In 35 seconds
- The model uses AI post-processing that compares its inaccuracies with historical data to correct them.
- In the 2 to 6 week range, overall forecast accuracy doubled.
- Three versions of the model were tested with the ECMWF system, based on historical climate averages.
