Moisture fluxes and precipitation in Europe
Lemarie, Petr ; Müller, Miloslav (advisor) ; Šmídová, Jana (referee)
The present thesis deals with the influnence of moisture flux and variables, it is derived from, on rainfall in Europe. Sources of this thesis are the NCAR/NCEP and the ERA-40 reanalysis and the GPCC and the ECA&D rainfall databases. A western moisture flux prevails on studied 850 hPa isobaric level, it reaches the highest intensities over the Atlantic around 55th parallel of latitude. There is the highest correlation between moisture flux magnitude and monthly rainfall in winter on the western coast of Europe and it decreases in summer and eastwards. The correlation is very weak or none in some parts of Europe, especially in the eastern Mediterranean. Extremely wet months are related with different intensive moisture flux directions in different parts of Europe, for example there is the highest correlation of monthly rainfall with the northern moisture flux in the Czech Republic. Several selected heavy precipitation episodes in Europe are presented in this thesis - during them the moisture flux anomaly is observed, but it differs in orientation and intensity. A high wind speed causes this anomaly more frequently than a humidity. This does not apply to every event, furher research is needed to draw general patterns of moisture flux during high precipitation events.

Wireless weather station
Filka, Tomáš ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This diploma thesis deals with a draft of wireless weather station, whose task is to measure basic values inside and outside the home. Measured variables are for example temperature, atmospheric pressure, relative humidity, wind speed and direction or concentration of carbon dioxide (CO2). These data will be transmitted to a web server for later processing. Possible technical solutions are described and the outcome is a designed printed circuit boards, which has been assembled and tested. Resulting system was tested in trial operation.

Simple FITkit Based Weather-Station
Podivínský, Jakub ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
In this bachelor thesis, the design and implementation of FITkit-based home weather-station is presented. In the thesis, various methods of measuring meteorological quantities are detailed and discussed together with advanteges and disadvantages of common electronic sensor parameters. Then, weather forecast methods are classified and principle of a simple weather-forecast algorithm based on the atmospheric pressure measurement and analysis is described and discussed according to its realization by the means of the FITkit platform. At the end of the thesis, design and realization of an additional hardware needed to operate the station on basis of FITkit is described.

Miniaturized Measurement System for Wind Speed Estimation.
Štěpánek, Michal ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
This thesis is analysis of thermal anemometer, which contains design and realization. For measuring wind speed there are not used any mechanical moving parts in this way. This measuring uses two thermistors. One of these measures temperature of air, which is very important for compensation of whole system. Temperature of second thermistor is kept on constant value. This value is higher than surrounding air temperature about constant difference. Fluctuant air cools this sensor and because of that systém must supply more of heat. By analysis of value of supplied heat, we can calculate the wind speed value.

Weather Station
Beneděla, Pavel ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This thesis deals with conception of proposal and implementation of a weather station. Weather station is composed of three main parts which are measuring station, showing station and USB wireless receiving module. Measuring station measures basic meteorologic variables and sends measured variables through wireless communication. Showing station is designed to present measured data with graphics user interface and generate data for a web server.

Passenger vessel consumption computation
Drbohlav, Lukáš ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
This thesis is focused on a design and an implementation of a power consumption computation for a passenger vessel using the industrial automation system Siemens Simatic S7-200 and the touch panel Weintek Easy View MT8150X. A part of the thesis represents a theoretical summary of features and parametres of the programmable logic controllers (PLC) and a way how they are programmed. The work includes a description of a computational algorithm, a block diagram of interconnections and a visualization software for testing. A greater part of this publication is devoted to a detailed decription of a program in the PLC and its visualization, especially the power consumption computation, a distance, an average speed and a wind speed and a direction. At the end, the thesis shows a procedure for an implementation and a measurement on the passenger ships at the Brno dam, including an evaluation of downloaded data.

Evaluation of meteorological data in the locality FME BTU Brno
Drábek, Ivo ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
Content of this bachelor´s thesis is evaluate meteorological data which were measured by sensors of temperature, humidity, barometric pressure, wind speed and wind direction which are placed on a station of Energy institute. Data were measured from the 1st October 2008 to the 30th September 2009. The thesis briefly characterizes evaluating quantities, sensors which were used for measuring, tables content evaluated data and their ilustration by graphs.
