Conditions for tornadoes forming over the Czech Republic
Seidlová, Jana ; Vokoun, Martin (advisor) ; Soukupová, Jana (referee)
The goal of this bachelor's thesis is to review a situation of tornadoes, occurrences of tornadoes and also results of violent winds which accompany thunderstorms above Czech Republic region.
The first part looks at conditions required for the formations of tornadoes starting from a clear sky up to thunderstorm cloud. Then it describes development from a thunderstorm and associated hazards up to a tornado. Between main conditions belongs an unstable air mass which reaches high altitudes, high relative humidity, wind shear and vorticity. It also describes real occurrences of stronger tornadoes at Czech Republic.
In following part there are processed results including comments with graphical outputs from individual data gathered from particular occurrences. The time span of this thesis is limited by availability of historical data (chronicles, etc.) and they are processed from year 1500 up to year 2015. Results of analysis include remarks and they are refined
in discussion. For further and more complex overview about tornado occurrences at our country is necessary to have larger quantity of more precise data.

Climatic Changes After The Eruption of Tambora in 1815
Zhao, Shuran ; Soukupová, Jana (advisor) ; Bašta, Petr (referee)
Volcanic activities belongs to the most common natural events on this planet. They are as old as our planet. Some volcanoes have very long life cycle, their interval of eruptions can be up to tens or hundreds of thousands years. In general, the long interval the large eruption. The super-eruptions on VEI 8 are able to destroy the whole human civilization on the world. Fortunately this kind of eruptions is very rare from the human perspective.
Other weaker eruptions happen more frequently. Human civilization experienced an eruption of VEI 7 in 1815, which was the biggest eruption during last 10 000 years and led to global cooling and famine. That was the biggest volcanic eruption in human history, eruption of volcano Tambora in 1815.
Tambora during its eruption released a tremendous amount of magma and volcanic gases. It has been unsurpassed till now. It had severe consequences, many people were killed by the eruption but even more people died as a result of diseases or starvation related to eruption. In next 2 to 3 years after eruption, Northern Hemisphere was in an unstable condition. A huge amount of volcanic gases and ash released by this eruption was transported into stratosphere that led to global cooling. Just the cooling destroyed many fields and killed lots of people. So that year 1816 get a name as year without summer. In my work I collected information and data of weather during 1815 to 1817 around Northern Hemisphere to compare them and to find out whether the eruption changed the climate after 1815. Many sources recorded an unusual weather in North America, Asia and Europe. In these years, it was always cloudy and persistently rained. The Czech lands were also affected by this eruption. Many Czech sources recorded cold weather in 1815-1817 that related with widespread rise in price of agricultural products. It undoubtedly worsened the already grave situation.
Such these eruptions are big threat to human civilization. We cannot avoid them, but we can reduce the consequences to a minimum by monitoring volcanoes and their activities.
The aim of this work is describe the climatic changes accompanied with the big volcanic eruption of 1815 and its consequences. I am trying to restoring the details of volcanic eruption. My aim is to draw attention to the danger of volcanic activity and the importance of monitoring volcanoes.

Pluvial and climatically favorable years 1770-1773
Mičková, Iva ; Soukupová, Jana (advisor) ; Vokoun, Martin (referee)
The purpose of this thesis is to offer a complex picture of climate change during a short fourth pluvial period and its impact on humankind. Since there are countless number of sources and literature for every particular state, I focused mainly on a summary for the Czech Republic and touched on its neighboring countries. For a better comprehension of the whole picture of contexts, I have also mentioned Little Ice Age period, where the third and the fourth pluvial period belong to, and its possible causes and causes of the climate change in general in the beginning of the thesis. In its final part the thesis has evaluated the impact of this period on humankind. The purpose of the thesis is to draw credible consequences from the available sources for the analysed territory.

Biogas plant Žákava
Saláková, Veronika ; Synáčková, Marcela (advisor) ; Soukupová, Jana (referee)
The bachelor thesis deals with the production of energy from renewable sources using biogas. The introduction talks about the history of these special-purpose constructions, which are able to produce a range of products. These products are mainly biomass and biogas, extracted from many processes from sewage sludge and containing a substantial portion of methane, generally known as the main component of natural gas. Combustion of biogas in cogeneration units produce electricity and thermal energy.
The theoretical part is devoted mainly to the production of green energy from organogenous sludge draining to the wastewater treatment plant, agricultural sludge and other kinds of sewage sludge. Next objective in sewage sludge cleaning is to prevent emissions and other adverse effects affect human health and the environment in accordance with legislation.
An example is the selected agricultural biogas plant Žákava, which deals mainly with the production of biogas from organic materials and its main source of income is the sale of electricity.
The intention of the bachelor thesis is a comparison of production of alternative energy not only using biogas plants and determination of limits for the disposal of sewage sludge due to the waste policy of the EU.
