Why weather forecasts can’t ever be 100% accurate
Forecasts rely on limited real-time data and chaotic atmospheric behavior, resulting in unavoidable uncertainty despite advances in technology and modeling.
- Meteorologists say predicting Earth's atmosphere isn't perfect because we sample roughly one data point per trillion cubic feet using satellites and ground-based sensors, leaving gaps in real-time observations.
- Over the world's oceans, large gaps force computer models to guess conditions because satellites can't measure everything, so scientists rely on buoys, ships and aircraft despite sparse coverage.
- Supercomputers solve thousands of equations for each of the millions of cubes, with global models updated every few minutes, hours, and days, according to meteorologists.
- Meteorologists note that today's forecasts are more accurate than ever, helping save lives and guiding farmers, shipping interests and communities.
- Despite added data from private-sector weather satellites, artificial intelligence , and crowd-sourced home weather stations and smartphone sensors, the atmosphere as a chaotic system causes forecast uncertainty to grow beyond a week.
