(University of Zilina, 2019) Jarošová, Miriam
Weather is limiting factor in planning of our activities. We often have to change our plans to avoid problems that the weather could bring. Transport, especially air transport is very sensitive to sudden changes of weather. For any mode of transport, safety, speed and efficiency is heavily dependent on current and expected weather conditions. Therefore, it is important to know very well the phenomena related to the atmosphere and selected mode of transport.
Comparison of fog occurrence at Slovak international airports for the period 1998-2018
(University of Zilina, 2021) Michalovič, Adam; Jarošová, Miriam
The aim of the paper is to analyze and compare the occurrence of fog at the international airports of the Slovak Republic in the years 1998-2018. 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%.

Flying in wave conditions, priciple of lfying in wave, history and dangers
(University of Zilina, 2021) Bajana, Ivan; Jarošová, Miriam
Flying in wave is becoming increasingly popular for pilots of gliders and sport engine airplanes. The growing trend of flying inwave conditions can be seen not only in Slovakia but almost all over the world The reason for the increase in the number of the high-altitude flights in the wave is their great potential, which has been demostrated several times in the record books. On the cotrary, for navigation and training flights, the occurence of wave current is unsuitable. It brings with it great risks and dangers that have ended tragically many times in history. For this reason, there is a long and extesive meteorological preparation behind the wave flights. The aim of wave conditions research is to provide information on how to predict wave flow, under what conditions and with at least what equipment it is possible to fly sadely in wave current and what pitfalls and risks wave wave brings with it. The result is a range of information that can be used not only for flights into the wave but also for normal navigation or training flights.

Weather influence on flight in mountain terrain
(University of Zilina, 2021) Galko, Róbert; Jarošová, Miriam
The 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.
