On the Ever-Increasing Accuracy of Weather Forecasts
Hannah Ritchie, writing for Our World in Data:
It wasn’t until 1859 that the UK’s Meteorological Service (the Met
Office) issued its first weather forecast for shipping.
Two years later, it broadcasted its first public weather forecast.
While meteorological measurements improved over time, the massive
step-change in predictions came with the use of computerized
numerical modeling. This didn’t start until a century later, in
the 1960s.
Forecasts have improved a lot since then. We can see this across a
range of measurements, and different national meteorological
organizations. The Met Office says its four-day forecasts
are now as accurate as its one-day forecasts were 30 years ago.
When I was a kid it was a running gag that weathermen were always wrong. I can’t remember the last time I heard anyone joke about weather forecasts being useless. Over the last 40 years, 7-day forecasts have gone from a coin toss to “highly accurate”. (Via Kottke.)
