Quizplus · Accepted Answer

During changeable weather conditions, the persistence forecast, which assumes that the weather will remain the same as it is currently, is usually the least accurate method. The trend method and analogue method take into account changes in weather patterns and historical weather data, respectively, making them more accurate. Probability forecasts use mathematical models to calculate the likelihood of a certain weather outcome, making them more accurate than persistence forecasts but not necessarily the best choice in changeable weather conditions.
