Winter Regimes
Abstract
This technical note presents a back-to-basics approach to forecasting the stronger, more dynamic weather systems of winter. Although it is especially designed for new and inexperienced forecasters, it is also an excellent review for all forecasters. As winter approaches, the subtropical ridge begins to drift southeastward with its effects lessened. The polar jet shifts southward and results are drastic changes in weather conditions within as little as 24 hours as blasts of colder polar air become more frequent. This technical note presents synoptic patterns and regimes that routinely occur during the winter months. Synoptic pattern recognition remains one of the most important considerations when producing a forecast and will help in determining if model guidance is 'on track'.
