Weather Forecasting Accuracy and Models

The video discusses the evolution of weather forecasting accuracy, noting that today's 3-day forecasts are as accurate as 1-day forecasts from the 1970s. It highlights the role of Chaos Theory in limiting long-term predictions and compares the performance of the American GFS model and the European model, with the latter generally being more accurate. The video concludes by comparing weather forecasting accuracy to other professions, emphasizing its relative reliability.

How does the accuracy of a 3-day weather forecast today compare to a 1-day forecast in the 1970s?

• It is less accurate.

• It is equally accurate.

• It is more accurate.

• It is not comparable.

What percentage of the time are one-day temperature forecasts within 3 to 4 degrees of being correct?

• 80%

What does Chaos Theory suggest about the predictability of weather forecasts?

• Forecasts become more accurate over time.

• Weather patterns are completely random.

• There is no limit to how far out you can predict.

• Random fluctuations can lead to significant changes over time.
