| Description | Extremely cold/mild winters (DJF) and extremely cold/warm summers (JJA) were derived from series of temperature indices (1500-1854) based on documentary evidence and from series of measured air temperatures at the Prague-Klementinum station (1771-2007) in the Czech Lands over the past 500 years. Altogether 24 cold winters, 23 mild winters, 18 cold summers and 21 warm summers emerged. Czech extremes were compared with the Central European temperature series and series of documentary-based temperature indices for the Low Countries, Switzerland and Germany. Analysis of composite sea level pressure fields confirms advections of cold air from the north-west (extremely cold JJAs) or from the east (extremely cold DJFs). Mild DJFs are related to warm airflow from the west or south-west and extremely warm JJAs to the influence of higher pressure related to the Azores High. Spatial correlations of extremes for DJF proved better than for JJA. We demonstrate that documentary evidence explains temperature variability for DJF better than it does for the other seasons. |
