AI weather forecasting is good for 15 days out.

This is the latest news from an article published in Barron's called, "Google Says AI Weather Model Masters 15-day Forecast". Check it out.

The top takeaways from the article are these:

"The European Centre for Medium-Range Weather Forecasts (ECMWF) produces predictions for 35 countries and is considered the global benchmark for meteorological accuracy. But DeepMind said GenCast surpassed the precision of the center's forecasts in more than 97 percent of the 1,320 real-world scenarios from 2019 which they were both tested on."

"The model was trained on four decades of temperature, wind speed and air pressure data from 1979 to 2018 and can produce a 15-day forecast in just eight minutes -- compared to the hours it currently takes."

"GenCast provides better forecasts of both day-to-day weather and extreme events than the top operational system... up to 15 days in advance," a DeepMind statement said."
