Autumn Regimes
Abstract
This technical note presents a back-to-basics approach to forecasting the weather in this transition from the weaker, slower moving weather systems of summer to the stronger more dynamic weather systems of winter. It is especially designed for new and inexperienced forecasters but it is also an excellent review for all forecasters. As summer ends, the subtropical ridge begins to retreat drift southeastward. The polar jet begins to shift farther southward and polar air intrusions become more frequent as autumn progresses. By the end of the autumn transition period into winter drastic changes in weather conditions become more common. This technical note presents synoptic patterns and regimes that routinely occur during the autumn months. Synoptic pattern recognition remains one of the most important considerations when producing a forecast and will help in determining if forecast model guidance is "on track."
