Prognosehorisonter

Prognosehorisonter refers to the time span into the future for which a forecast is made. Different fields use this term with varying specific meanings, but the core concept remains the duration of the prediction. In meteorology, a short-range prognosehorison might extend a few hours or days, while a long-range forecast could cover weeks or months. Economic forecasts also have distinct prognosehorisonter, such as quarterly reports or annual projections. The reliability of a prognosis generally decreases as the prognosehorison increases. Factors that are predictable in the short term can become highly uncertain over longer periods due to the accumulation of small errors or the emergence of unforeseen events. Understanding the prognosehorison is crucial for interpreting the confidence associated with a particular forecast and for making informed decisions based on its predictions. The choice of an appropriate prognosehorison depends on the nature of the phenomenon being forecasted and the purpose of the forecast itself. For instance, a business planning inventory might require a shorter prognosehorison than a government agency planning infrastructure development.
