Cycling Mechanism/Linguistic Fluidity
Dlabaja, Martin ; Lungová, Barbora (referee) ; Sterec, Pavel (advisor)
The main purpose of this work is to show relative scales of temperature changes during holocene and pleistocene [1.] using evaluated combined data sets from Greenland Ice Core Project and Vostok Ice Core project [2.]. Projects are researching values of CO2 in atmosphere using deep drills into sedimentary ice sheet layers corresponding in its maximum depth (approx. 3 km) to 800 kyr BP [3.] Values of CO2 correlates with temperature [4.]. Then we can lay out different cultural peak events on weather background and analyze the influence of temperature changes on rise and fall of empires, (Mesopotamia, Egypt, Shang, Indus, Rome) or study dramatic extinction events (Younger Dryas), watch the very beginning of culture in Fertile Crescent to witch trials in european “dark ages” in very close and evident correlation to weather change. Second goal is introduction to perceiving deep time as such.Third would be to raise questions and discussion about our own supposedly rigid timeline given to us by archeology by purposefully picked events such as meltwater pulses in Younger Dryas. (Lost cultures in Younger Dryas? Boloid impacts? Immediate emergence of writing systems without any proto evidence?) Of course a point of this work I didn’t mention is to present scientific data in aesthetically pleasing and effective way. These researches can be really “mind-blowing” if presented thoughtfully, (here in a way that is both attractive and shows scales and impact on our present day in a context of a global warming), but stays hidden from common knowledge due to for some “sterile” presentation in data sheets, which can be hard to read and make sense out of for people missing context.

Spatial and temporal distribution of precipitation in the Vosges mountain range area
Minářová, Jana ; Müller, Miloslav (advisor) ; Šmídová, Jana (referee)
Spatial and temporal distribution of precipitation in the Vosges mountain range area Abstract The aim of this work is to study the climatology of atmospheric precipitation in the studied area situated in the Northeastern France. Factors, e.g. the global circulation of the atmosphere, that influence the spatial and temporal distribution of precipitation in the mid-latitudes, especially in Western Europe and in mountainous regions, are discussed from the macro- to micro- scale in the first part. The term "ombric continentality" is clarified and a description of the physical geography of the studied area is performed, e.g. upward and windward asymmetry of Vosges slopes and contrasts between the mountain range and the Upper Rhine Plain. Secondly a demonstration is made that the Vosges mountain range affects, due to its position, the spatio-temporal distribution of precipitation at a regional scale. This is carried out by computing the daily rainfall on 14 meteorological stations out of the period 1951-2011. Three categories of stations were determined according to their annual precipitation repartition: (i) mountain stations with the winter precipitation maximum, (ii) leeward slope stations with two precipitation maxima, i.e. in winter and summer and (iii) leeward stations located in the Upper Rhine Plain East...

A climatological view of atmospheric fronts
Švábek, David ; Huth, Radan (advisor) ; Gvoždíková, Blanka (referee)
This bachelor thesis is focused on a climatological view of atmospheric fronts, which in middle latitudes greatly determine weather and its changes. Scientific literature is reviewed in the text, accompanied by manifestations of atmospheric fronts in a global and local scale for the areas of western and especially central Europe, whereas connection with temperatures, precipitation and other meteorological elements and it's long-term changes are emphasised. Further, the thesis is focused on problems connected with atmospheric fronts detection which is directly related to the most common places of occurence. The objective of the practical part is an analysis of the atmospheric fronts passages over the Praha-Ruzyně meteorological station during twenty year period from 1. 12. 2000 to 30. 11. 2020 with emphasis on winter and summer months. Key words: atmospheric fronts, climatology, temperature, precipitation, climate variability

Analysis of Selected Climatological Time Series
Kraitz, Petr ; Helman, Karel (advisor) ; Šimpach, Ondřej (referee)
Dissertation is focused on analysis of time series of monthly mean temperatures of seven meteorological stations between years 1960 to 2015. With the use of selected statistical methods time series are modelled in moving ten year long intervals and a forecast of elevenths year is constructed. The goal of this dissertation is to compare the success of different methods/models predictions of values for one year period, based on the data from last 10 years.

Influence of weather and climate on Ips typographus calamities in Šumava mountains
Tůma, Lukáš ; Sládek, Ivan (advisor) ; Kožnarová, Věra (referee)
European spruce bark beetle (Ips typographus) is a natural forest pest that feeds on coniferous trees, mainly on spruce. Previous studies showed that population growth of bark beetle is supported by warm and dry weather and hindered by cold and humid weather. Temperature affects development rates and influences the number of generations bark beetle may produce during one season; furthermore, it affects survival rates during the winter. Low precipitation leads to water stress of spruce trees which become more prone to bark beetle infestation. High precipitation promotes growth of mold and other natural enemies of bark beetle. The aim of the experimental part of this thesis was to analyze the relationship between population dynamics of bark beetle and weather, using data from the Šumava national park. Data did not show a significant effect of temperature and precipitation on the population growth rate of bark beetle. The growth rate was significantly correlated only with the abundance of bark beetle in the previous year. For further examination of population dynamics of bark beetle in connection with climate characteristics, it would be required to obtain better and more long-term data on bark beetle abundance; harvested bark beetle wood may be influenced by a variety of interfering (e.g....

Summary of hailstorm climatology
Brych, Jan ; Müller, Miloslav (advisor) ; Chládová, Zuzana (referee)
The aim of this thesis is to point out the frequency of hailstorm in the world per year. In the first part we describe the genesis of hailstorm and most used methods for hailstorm detection. In the last part we describe summary of areas in selected countries with the biggest frequency of hailstorm and its annual variation. Here we try to point out the spatial scatter of affected areas. Also we try to describe the most basic hailstorm - affecting factors with the analysis of frequency of distribution in individual countries. By these factors (geographical latitude, height above sea level, influence of topography and atmospheric circulation) we try to clarify the affecting reason of genesis and power of hailstorm. Key words: hailstorm, hailstone, detection of hailstorm, climatology, factors Powered by TCPDF (www.tcpdf.org)
