Weather Forecast Accuracy
Hello dear visitors! This website investigates the accuracy of weather forecasts. We experimentally determine the accuracy of weather prediction on various weather websites for different cities. This allows us to determine the location of each weather website, depending on the accuracy of the forecast.
Forecasts for observed cities from different websites
And now look at today's forecast of the maximum daily temperature for Beijing from different websites.
Each column of the table corresponds to a certain depth of the forecast in days. The numbers in the cells are the estimates of the accuracy of the forecast (in this case these are the mean square deviations of the forecast errors) and the number of measurements. The smaller the estimates, the more accurate the forecast. Each cell is colored in a certain color, which determines the place of the website by accuracy. Green color corresponds to the best result, red - the worst.
