Long-range forecasts are given as a probability (or chance) of exceeding a specific threshold.Due to the high variability of rainfall, and that in some locations just one or two extremely wet years can substantially change the overall average, using the median is the best representation of typical rainfall that would be expected.ĭetails: Medians Rainfall long-range forecasts The median is the middle value when a set of values are ranked from lowest to highest. Download schedule as calendar file (ICS).ġ Median is a measure of what is considered typical rainfall or temperature for a specific location similar to mean.Climate and water long-range forecast videos: twice a month on Thursdays.One and three month forecasts: Thursdays at 3pm AEST/AEDT.One and two week forecasts: Daily around 3pm AEST/AEDT.Read our blog: What to expect from the climate when the forecasts are neutral The greatest benefits of using Bureau long-range forecasts will accrue from use over a number of seasons or years. Probability-based long-range forecasts are designed to be used as one of several planning tools within risk management and decision-making.Advances in modelling and computing power have allowed us to look at shorter timescales, making possible accurate predictions for sub-monthly timescales. However, longer-term forecasts of seasonal statistics, such as whether rainfall or temperature will generally be above or below median, are possible to accurately predict. This is because the further we look ahead, the more small random changes can amplify into different weather patterns. While weather forecasts can tell you what the temperature will be tomorrow and how much rain to expect, long-range forecasts cannot be this specific.Model: The long-range forecasts are generated from the Australian Community Climate Earth-System Simulator–Seasonal (ACCESS-S), the Bureau's dynamical (physics based) climate model.Temperature: the likelihood of unusually cool/warm or wet/dry conditions is provided by the chance that the forecast will result in conditions in the top or bottom 20% of historical observations.ĭifferences between 'Long-range forecasts' and 'Weather forecasts'.The values provided are the middle of the predicted scenarios-also known as the ensemble mean. ![]() They show how far above or below the 1981–2018 average the temperature is likely to be (1981–2018 is the model period see Medians tab). Available for the weekly and fortnightly timescales.
