Flight planning and performing according meteorological forecasts
Zapletal, Jan ; Hammer, Jaromír (referee) ; Krška, Karel (advisor)
This bachelor thesis deals with meteorological elements and phenomena with respect to aviation. It focuses on sources from which it is possible to obtain the necessary forecasts and weather information, both in flight planning and execution. The author, as a competition pilot, performs an analysis of specific flights, during which he had the opportunity to evaluate and compare the quality of weather information from various sources and their implications for sports performance.

Meteorological information sources for air crews
Polanský, Lukáš ; Šplíchal, Miroslav (referee) ; Krška, Karel (advisor)
This bachelor thesis is focused on the description of meteorological phenomena factors and clouds affecting air transport. Furthermore, the potential avenues of disseminating available meteorological information and a modern way of providing the aircrew with information is described. The aim was to create a comprehensive set of information on aeronautical meteorology that may be beneficial for the general public.

Dependence of aerosol activation on meteorological conditions
Zíková, Naděžda ; Pokorná, Petra ; Sedlák, Pavel ; Ždímal, Vladimír
Four intensive in-situ campaigns focused on aerosol-cloud interactions were performed in the autumn and spring months from Nov 2018 to Apr 2020 at Milešovka Mountain in Czechia to bring more insight into size-dependent aerosol activation and dependence on its origin for a wide variety of meteorological parameters. Most activated particles were larger than 100 nm, with a mode over 200 nm. For the description of the changes in the activation, no effect of photochemistry was found, in contrast, some dependence on relative humidity, temperature, wind speed, and liquid water content (LWC) proved to be useful. The strongest connection was found between activation and LWC. For LWC below 0.1 g/m3, in the LWC-limited regime, the LWC values and variables effecting the LWC were the main factors influencing the activation, while different parameters could have played a role at LWCs over 0.1 g/m3, in the LWC-independent regime.

What is a connection between atmospheric aerosols, meteorological parameters and gaseous pollutants?
Slezáčková Zíková, Naděžda ; Ždímal, Vladimír (advisor) ; Hovorka, Jan (referee) ; Sedlák, Pavel (referee)
Title: What is the connection between atmospheric aerosols, meteorological pa- rameters and gaseous pollutants? Author: RNDr. Naděžda Slezáčková Zíková Department: Department of Meteorology and Environment Protection Supervisor: Ing. Vladimír Ždímal, Dr. Laboratory of Aerosol Chemistry and Physics, Institute of Chemical Process Fun- damentals, Czech Academy of Sciences, v.v.i. Abstract: Five years of atmospheric aerosol (AA) measurements at rural back- ground station Košetice were compared with meteorological records and gaseous pollutants concentrations. The sampling and data analysis of AA data is de- scribed, and the statistical evaluation is done. The variability in the AA con- centrations is significant; the long-term measurements of AA, over the period at least several years, and the differentiation according to the season of the year are thus necessary. The clearly expressed annual cycle of AA concentrations is mainly influenced by two phenomena. From April to September, the total AA concentration cycle is driven mainly by the new particles formation events, from October to March, the concentrations are strongly influenced by particles coming from long-range transport and/or from the regional pollution. The relationship between AA and meteorological parameters, however, is not only season...
