	Statistical model of urban heat island characteristics in Central Europe Vacík, Pavel ; Hošek, Jiří (advisor) ; Láska, Kamil (referee) Urban heat island (UHI) is a region of increased air temperature in the canopy layer and boundary layer of the atmosphere above the town or industrial agglomeration in comparison with rural surroundings. The difference in temperature increases with the size of the city. This study describes the dependence of the intensity UHI Central European cities on their size and position of their weather station. It uses a multiple linear regression model. The dependent variable Y entering the model (data from 40 cities) are UHImean and UHImax. They are calculated as difference in air temperature between the urban and the relevant rural weather station. The average intensity of the urban heat island (UHImean) is the average value of the UHI of all available data in the analyzed period (hourly measurements of air temperature [řC] for the years 1994-2012). The data are only taken from night times records between 21:00 and 4:00 UTC and on days with the average total cloud cover at the city weather station less than 0,5. The maximum intensity of the urban heat island (UHImax) is the average maximum value of the UHI per night. The data are taken under the same conditions as in the case of UHImean. Independent variables X are the size of built-up area (X1) and the position of the weather station calculated using the... Detailed record
	Climatological and phenological conditions of Tušimice observatory Hájková, Lenka ; Sládek, Ivan (advisor) ; Láska, Kamil (referee) ; Žalud, Zdeněk (referee) The thesis is aimed at climatological, agroclimatological and phenological conditions at Tušimice observatory during 45 years of observations (1968-2012) on basis of meteorological and phenological data by using statistical methods, method of cumulative series and geographical information system. Basic climatic elements (air temperature, precipitation total, snow cover, cloudiness, wind, humidity, sunshine duration, fog and thunderstorm), agroclimatic characteristics according to the WMO recommendation, selected phenological phases (mainly beginning of flowering 10 %) of herb and wooden species were processed in the study. The literature overview was made on climatic and phenological conditions at Tušimice station, in the Czech Republic and other countries. Apart from statistical analysis, the elements were also evaluated in the interaction with the changing air circulation in Central Europe. In addition, results were compared to Quitt's classification based on long-term averages of meteorological data (1961-1990 versus 1981-2010). The drought occurrence was evaluated in 45 years of observations period. The thesis is divided into three main parts - Climatic conditions of Tušimice observatory (part 5.1), Agroclimatic conditions of Tušimice observatory (part 5.2) and Phenological conditions of...
