This scientific thesis was developed under the supervision of the thesis supervisor. For the analysis, we used METAR reports provided by the Slovak Hydrometeorological Institute.Item Influence of meteorological conditions on aircraft take - off and landing(University of Zilina, 2022) Chynoranský, Jakub; Jarošová, MiriamThe division of meteorology is an integral part of aviation that informs about meteorological phenomena and defines their nature. This article focuses on the types of meteorological conditions with which the aircraft comes into contact during the flight, with a closer focus on the take-off and landing phases of the aircraft. The topic of meteorological conditions and their effects was chosen due to the enormous importance of this segment of aviation for the safety and operation of air traffic. The paper has a theoretical character and approaches the connection between individual meteorological conditions and their effect on the behavior of the aircraft. For air safety, a proper interpretation and subsequent adaptation to the corresponding weather events and deviations from standard conditions is essential. The aim of the publication is to define the basic meteorological conditions, weather phenomena and to underline their considerable importance for air traffic. The final part is devoted to the analysis of air accidents during takeoff and landing, which were caused by adverse weather conditions and their underestimation.Item Meteorological information resources for aircraft crews(University of Zilina, 2022) Slušný, Radoslav; Jarošová, MiriamThis article addresses the issue of available meteorological information resources and their importance for aircraft crews, with special regard to the ways of disseminating meteorological information and the possibilities of providing it to crews. The aim of the article is to process a comprehensive set of information about meteorological information resources and methods of obtaining meteorological information in aviation. The article has a theoretical character. It summarizes the basic terminology and defined concepts of the processed issues, with an effort for a logical focus of the chapters that are adequately addressed. In the discussion and conclusion, we pointed out the importance of meteorological resources for aircraft crews, the need for proper assessment and evaluation of the obtained meteorological information, in order to ensure the safe course of the flight.Item Turbulence as a dangerous weather phenomenon(University of Zilina, 2022) Martincová, Alexandra; Jarošová, MiriamThe aim of the theme is to examine and clarify the turbulent flow on a larger scale, especially for better flight preparation in the field of turbulence. The work explains the air flow, the formation of turbulent flow and its division into important species. It is solved how the Förchtgott classification is divided according to the type of flow on the leeward side of the mountain obstacle. At the end, it contains information on the written topic. The information is found to be that turbulence is a dangerous weather phenomenon to be taken into account, especially by the pilot so as the turbulence information has been clarified.Item Impact of clouds on the aviation(University of Zilina, 2022) Švancárová, Nikola; Jarošová, MiriamThe aim of the paper is to study concepts and types of cloud coverage and clouds itself.

The paper explains the influence of weather on the flight, the influence of meteorological conditions on visibility, defines the fog and describes the international airports - M. R. Štefánik Airport in Bratislava, Košice Airport, Poprad - Tatry Airport and Žilina Airport. Based on the analysis of METAR reports, we found that the average number of foggy days in the monitored period at Žilina Airport was 132.24 days per year. It is followed by Košice Airport (81.33 days), Poprad Airport (77.81 days) and Bratislava Airport (61.33 days). We attributed the high number of days with the occurrence of fog at Žilina Airport to its location, as there are up to nine water reservoirs and the main course of the Váh River in its vicinity. Bratislava Airport has ideal conditions in terms of visibility. According to METAR, 37 % of foggy days were recorded in autumn, 31% of foggy days in winter, 17 % of foggy days in summer and 15 % of foggy days in spring. At international airports, fog in the autumn meteorological period in the observed period from 1998 to 2018 occurred most often from 00:00 to 12:00, ie mainly in the morning and in the morning, with an incidence of 57 % to 71%.Item Weather influence on flight in mountain terrain(University of Zilina, 2021) Galko, Róbert; Jarošová, MiriamThe aim of the paper is to approach and get acquainted with meteorological elements that occur in mountain areas and how their occurrence affects the fluidity and safety of air traffic. The first part of the work was devoted to the history of observing meteorological conditions together with the development of monitored variables, their measurement scales and units used. Subsequently, climatology and meteorology were specified as scientific disciplines and weather in general. Furthermore, in the work we discussed in more detail the part of the atmosphere where the biggest changes in the weather and its creation take place. To illustrate the importance of monitoring and not underestimating meteorological phenomena, we emphasized the failure of the human factor in the most tragic aviation accident that occurred on the island of Tenerife. In the penultimate part of the theoretical part, we paid attention to the meteorological elements themselves, which have the greatest impact on aviation in mountainous areas. In the last theoretical part, we talked about aerial weather reports, which we also decoded. In the practical part, we characterized the airport Poprad-Tatry in terms of location in relation to the surrounding mountains and observed how the investigated meteorological elements affect the area.
