On the Duration of Widespread Fog and Low Ceiling in Central Europe and Some Aspects of Predictability
Abstract
The duration of adverse weather over Central Europe has been analyzed. After a definition of adverse weather, the duration in hours and days is given. While the median of the frequency for the hours fluctuates between 4 to 8 hours in winter at a single station, the duration in days ranges in the average between 2 and 3 hours. In 10% of the cases, adverse weather exceeds between 16 to 24 hours, while 10% of the cases lasts more than 4 to 7 days in the winter months. Station combinations to assess the duration of adverse weather over an extended area provide the same result in days. Several models have been considered and speculative numbers were obtained. Evaluation is based on the large-scale weather patterns over Central Europe (Grosswetteriagen (GWL)) and their relationship with adverse weather.
