    Identifikácia poveternostných podmienok na základe výskytu oblakov
    (University of Žilina, 2025) Fomina, Anna; Jarošová, Miriam
    This article focuses on the relationship between different cloud types and specific weather phenomena, as well as the potential of using cloud observations for short-term weather forecasting. The research is based on the analysis of METAR reports collected at Žilina Airport during the summer months of 2024 (June–August). The study aims to identify typical features of cloud development under various synoptic conditions—such as the passage of cold fronts, periods of atmospheric stabilization, and the occurrence of convective storms. The goal is to evaluate the extent to which visual observations of clouds can improve the effectiveness of short-term forecasts and complement standard meteorological methods, thereby supporting aviation safety.

    História leteckej meteorológie
    (University of Žilina, 2025) Havlík, Timon; Jarošová, Miriam
    This article traces the evolution of aviation meteorology from its earliest synoptic observations to today’s AI-driven forecasting systems. Through a structured literature review and analysis of key milestones—ranging from Aristotle’s Meteorologica and early instruments (anemometer, barometer) to the establishment of Meteor R.E. in World War I, the METAR/TAF standardization in 1968, and the founding of ECMWF—this study highlights how terminology, data formats and distribution methods have continuously advanced. A comparative assessment of past and present practices reveals dramatic improvements in data timeliness (hours to seconds), measurement accuracy, and global coverage via SOS/AWOS, GTS/SWIM and satellite networks (MetOp, Meteosat). Finally, it examines emerging applications of AI and support vector machines for hyperlocal nowcasting and 4D trajectory planning, underscoring the need for ongoing international collaboration and technological innovation to meet the challenges of an ever-changing atmosphere.

    Výška základne oblačnosti na Letisku Žilina pri rozličných poveternostných situáciách
    (University of Žilina, 2025) Hromadík, Matej; Jarošová, Miriam
    This paper focuses on the analysis of cloud base height at Žilina Airport under various weather conditions. The objective of the paper is to analyze the cloud base height in relation to atmospheric fronts, pressure systems, and associated meteorological phenomena that directly affect the safety of air operations, with particular emphasis on training flights conducted under Visual Flight Rules (VFR). The study utilizes METAR reports and synoptic maps provided by the Slovak Hydrometeorological Institute (SHMÚ). The months of August and November 2024, and January 2025, were selected for examination. Based on these data, an analysis was conducted of the occurrence of different cloud types, their base heights, and related weather phenomena such as fog, rain, thunderstorms, and reduced visibility. The results highlight typical cloud development patterns under specific synoptic conditions, contributing to better planning of air operations and enhancing safety, especially during training flights. The thesis also provides recommendations for increased attention during particular weather situations that may lead to limitations or complete suspension of flight operations.

    Projevy klimatické změny na vybraných letištích Slovenska
    (University of Žilina, 2025) Janošková, Alena; Jarošová, Miriam
    The topic of this article is focused on the impact of climate change on the increasing tendency in the occurrence of hazardous weather phenomena at selected airports in Slovakia. The aim of the article is to confirm or refute the influence of climate change on the increasing frequency of meteorological phenomena in the specified time frame from 2000 to 2019 by means of a comprehensive statistical analysis and statistical summarization of meteorological data. The first part of the article defines the basic terminology related to the climate change and specifies the importance of addressing the issue in the context of aviation safety. For the practical part of the article meteorological reports provided by the Slovak Hydrometeorological Institute were used. In the practical part, various statistical methods, and a comprehensive evaluation of the frequency of individual weather phenomena during the analyzed years, were used. The hypothesis of increasing frequency of weather phenomena over the years was statistically confirmed only for thunderstorm activity at one meteorological station.
