The applicability of the Hess-Brezowsky synoptic classification to the description of climate elements in Europe
Sýkorová, Petra ; Huth, Radan (advisor) ; Racko, Stanislav (referee)
This thesis deals with the applicability of the Hess-Brezowsky synoptic classification to the description of climate elements, minimal and maximal temperatures and precipitation, in Europe. The first part of the thesis is an overview of the knowledge concerning circulation classifications (with emphasis on the Hess-Brezowsky synoptic classification) and its applicability to the description of climatic elements. In the second part of this thesis, the suitability of the Hess-Brezowsky classification for this purpose in the European domain is analyzed, using the two-sample Kolmogorov-Smirnov test. The test was performed on ECA&D data from 113 climatic stations for the years 1961 - 2000. The suitability of the classification for describing climatic elements at a given station was assessed according to the percentage of the synoptic types, during which the elements' probability distribution functions differed from the rest of the values. The classification was deemed most suitable for describing climatic elements in Germany and its neighboring states and least suitable in the Mediterranean and Eastern Europe. The classification was more suitable for the description of minimal and maximal temperatures than precipitation and less suitable for description of all climatic elements in the summer months than...

Changes in climate elements in central Europe and the Czech Republic from the mid-20th century, focusing on autumn
Maryško, Kryštof ; Huth, Radan (advisor) ; Cahynová, Monika (referee)
This thesis deals with climate elements changes in Central Europe in the 2nd half of the 20th century which are being compared to changes in global and European scale. The entire thesis is divided into three main chapters according to the climate elements. The most described are temperature indicators which the authors of papers study most frequently. Also the precipitation forms a separate chapter, while other elements are all summarized in one chapter, because there are not that many studies about them. The average annual temperature and precipitation trends calculated for Europe or the world were similar to those in Central Europe. As for the temperature indicators, during the 2nd half of the 20th century warming was found in most cases and insignificant trends prevailed for precipitation indicators. Among the seasonal changes in climate, autumn stood out. Its trends were in some cases (especially for temperature indicators) different from the other seasons. Whilst there is warming in Central Europe in spring, summer and winter, it cools in autumn. Keywords: climate elements, long-term changes, Central Europe, autumn

HAS THE CLIMATE CHANGE IN CENTRAL EUROPE BEEN ACCELERATING OR DECELERATING?
Maryško, Kryštof ; Huth, Radan (advisor) ; Pokorná, Lucie (referee)
6 Abstract The thesis deals with detailed analysis of the climate change rate throughout the European continent with an emphasis on Central Europe in the period 1951-2005. The main aim was to find out whether the rate of climate change is getting lower or higher during the monitored period and identify when the changes in the rate occurred. Changes of three climatic elements - minimum air temperature, maximum air temperature, and precipitation, were described for climatic seasons of the year. Other climatic elements were also available, however, amount of data is insufficient for such a detailed trend analysis for the entire second half of the 20th century. First part of the thesis summarizes current knowledge of changes in climate change rate, which is so far rather scarce. Most scientific articles are limited to detecting warming or cooling, decrease or increase in precipitation during a certain period. They, however, do not research when these changes of climatic elements occurred. For my analysis, which tries to offer a detailed insight into changes in European climate, daily records from European Climate Assessment and Dataset (ECA&D) database of 122 stations (spaced as evenly as possible) were used. For examining variability trends (i.e. the rate of climate change) I tested moving 20-year trend (15-...
