The consistency in the direction of their errors was the key to my best predict. In other words, there are forecasts too high one day and weak the next year. They made their mistakes in the same way on several occasions.

The next logical question is whether the errors are also compatible in other parts of the country. As for the statistics could answer this. You can check the high and low estimates of the last 365 days, and check the actual temperature of the day. We can also see that the predicted probabilities of rain or snow were, and record what has actually occurred.

For example, suppose a forecaster expects a 50% chance of rain 24 times, but it actually rained 18 times. It was perhaps the best evidence, but he was too cautious in its application. It can not be a problem spot. This can be determined by performing a more statistical analysis. If his error has been online, you know something about the weather and give a more accurate prediction simply by saying “A 75% chance of rain tomorrow” every time he said there was a probability of 50 %.

This is the essence of how this idea of ??the prediction of new works. First, need to collect statistical information and several forecasters predict weather forecasting services. Then compared these predictions with the actual time it happened, and seek constant errors. Ideally, you want to create a computer program, the idea that entering into each of these provisions in it have been adjusted for all known trends. The result should be more accurate weather predictions.

An example may clarify this. Suppose that last year was a predictor to predict high temperatures with an average of 4 degrees in the high real. The team adjusted its forecast by four degrees. Perhaps a closer analysis shows that Predictor B is still very high probability of a forecast of rain fall, but very low chance of rain in summer. Once discovered and programmed, the computer can adjust the forecast of these factors. For clarity, the projections set of three or more sources could be an average. No need to know something about the weather. The underlying idea is that even when experts with the best knowledge and data can be applied incorrectly, and they do it constantly.
