Abstract
Synoptic climatological analyses associated with the large day-to-day variation of air temperature around Germany in winter were performed based mainly on the NCEP/NCAR reanalysis data for 2000/2001 to 2010/2011 winters, with an interest in the relationship to the “seasonal feeling” in “Fasnacht”, the festival for driving the winter away. The intermittent appearance of the extremely cold days with rather large day-to-day variation in winter as pointed out by Kato et al. (2017) for around Germany was seen also to the north and to the east of Germany. According to a case study for the 2000/2001 winter, such large daily mean temperature fluctuation was closely related to the intraseasonal variation of the Icelandic low with about one month period, i.e., while the temperature around Germany was relatively higher at the eastward shift phase of the Icelandic low due to the strong warm air advection by the SW-ly wind, the temperature was extremely low there when the Icelandic low was weakened and retreated westward.
