Meteorological station system
Čada, Jan ; Balík, Miroslav (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with the design and implementation of a online meteorological station system, which consists of individual weather stations that communicate via the Internet with the server. The first part of the thesis discusses the principles of measuring major meteorological variables and deals with the selection of suitable sensors for measuring temperature, atmospheric pressure, humidity, wind speed and rainfall. In the practical part, one of the weather stations based on Raspberry Pi Zero microcomputer is designed and realized. As a complement to the measured data, the station includes a camera that captures the view from the site where the meteostation is installed. 3D printing is used to realize most of the mechanical parts, it has the advantage of speed, accuracy and easy reproducibility. For the measurement of temperature, pressure and humidity, a combined sensor BME280 from Bosch is used, which is placed in a small Stevenson screen. The wind speed is measured by a cup anemometer whose rotation is sensed by an integrated Hall sensor. The output pulses are then counted using the PCF8583 circuit, which has an I2C interface for reading the values with a Raspberry Pi microcomputer. Special attention is paid to the construction of a custom calibratable tipping bucket rain gauge with a resolution of 0,5 mm, whose mechanical motion is also sensed by a Hall sensor as in the anemometer. The reading of the data from sensors and sending it to the server is handled by a Python script. For storing and presenting data to users, a custom server solution based on LAMP webserver is implemented, its source codes are written in PHP, HTML, JavaScript and CSS. In addition to the web interface, which displays the data in graphs, the measured data can be also presented to the user via an application for mobile devices based on Android. The application was developed in C# using the Xamarin framework in the Microsoft Visual Studio development environment. Among other things, it implements a widget for quick access to the measured values directly from the home screen. In the final part of the thesis, interesting findings obtained by observing the measured values are mentioned.

Use of meteorology and historical comparisons atmospheric conditions for yachting and water sports
Hájek, Petr ; Jindra, Matouš (advisor) ; Dvorský, Jaroslav (referee)
Title: Use of meteorology and historicalcomparisons atmospheric conditions for yachting and water. Objectives: At work I use two basic methods of research. The method of content analysis and interview. Content analysis, I get the information for the theoretical part of the work, using professional sailing and meteorological publications. Furthermore, the method of non-standardized interview, which I took while visiting Mathematics - Physics Faculty at Charles University, Department of Meteorology and Climatology. Here I have discussed his work with Dr.. Joseph Brechler, PhD. Furthermore, with top windsurfing in the Black foothills and Nechranické dam. Methods: At work I used as a basic research methods method of content analysis and interview. Content analysis, I gained information for the theoretical part, the professional sailing and meteorological publications that deal with the issue. Non-standardized interview method I used when visiting Mathematics - Physics Faculty at Charles University, Department of Meteorology and Climatology. Here I discuss my work with Dr.. Joseph Brechler, PhD., Then Ing. Ružbatský in the foothills of the Black and F.Kasík of Nechranice. For wider acquaintance with the issues I was trying to get other sources of information on various internet portals related to...

Platform for Measurement of Atmospheric Quantities
Hanák, Jiří ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
This work is dealing with the design and implementation of an embedded system for aerology measuring. The aim of the system is to monitor atmospheric states during an ascent in the suspension under an meteorological balloon. First of all, attention is given to the Earth's atmosphere and its quantities, then an overview of existing systems for performing aerological measurements. The core of the work is focused on the choice of measurement techniques and the selection of suitable measuring elements for a given scenario. The aerological probe is using atmospheric sensors HIH-8131-021-001, MS5611-01BA03 and PT1000-550 for temperature sensing, while GNSS data is received using the MAX-M8Q-0 module and the measured data is stored on a microSD card and transmitted in parallel using the MTX2-434.650-10 radio module. The system is controlled by STM32L1 from STMicroelectronics programmed in C using HAL abstraction layer.

Volumetric Clouds
Barvíř, Marek ; Matýšek, Michal (referee) ; Starka, Tomáš (advisor)
This master thesis deals with creation of library for volumetric clouds. The paper describes specific techniques for creation and rendering volumetric clouds as clouds and atmospheric scattering. For rendering this type of effects we have to cover theory for participating media.

Emo Weather
Drštičková, Hana ; Šlesingerová,, Eva (referee) ; Sterec, Pavel (advisor)
The artwork was created by linking two thematic areas, mental health and atmospheric phenomena aka weather. I am examining forms of alienation and emotional numbness, which I follow by thematizing the isolation of people from the external environment and manifestations of local weather. I touch upon the topics of current weather representations, such as meteorological satellite images, and last but not least, I contemplate the fact of climate crisis. The work takes the form of a 100-minute long video, a set of 21 paintings by aniline colors on paper, sound track played in a loop and additional literature, texts and sketches available for public.

Platnost pranostik na území Jihočeského kraje v období 1981 - 2010
UHLÍKOVÁ, Renata
The bachelor thesis is occupying with chosen proverbs at the area of the Southern Bohemia in the period 19812010. As a part of my bachelor thesis I have used physical and geographical characteristics of the surveyed area with the focus on its windy conditions. My thesis as well contains the basic information about the athmosphere, proverbs and reformation of the calendar. The main part of bachelor thesis is describing the individual proverbs in detail and is applying several analitical methods for checking the indivisual sayings, their validation and evaluation. Last part of thesis is the outcome of the gathered checkings and evaluation of the given hypothesis.
