Abstract

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%.

Highlights

  • Jedná sa o problematiku mimoriadne širokú, v diplomovej práci nás zaujíma práve počasie, konkrétne výskyt hmly na medzinárodných letiskách SR

  • Graf 2 Výskyt hmly na medzinárodných letiskách v sledovanom období v meteorologických obdobiach

  • Na medzinárodných letiskách sa hmla v meteorologickom období jeseň v sledovanom období rokov 1998 až 2018 vyskytovala najčastejšie od 00:00 do 12:00, teda prevažne ráno a doobeda, s výskytom 57 % až 71 %

Summary

Introduction

Leteckú prevádzku najviac ovplyvňujú teplota vzduchu, tlak vzduchu, rýchlosť a smer vetra, oblačnosť, dohľadnosť, tvorba hmiel, zrážok a námrazy. METAR je označenie pre meteorologické správy z meteorologických staníc, ktoré letecká meteorologická služba prevádzkuje na letiskách s riadenou leteckou prevádzkou Bratislava, Košice, Poprad, Piešťany, Žilina a Sliač. Graf 1 Priemerný počet hmlistých dní na medzinárodných letiskách v sledovanom období. Práve vyparovanie vody z vodných nádrží a vodných plôch vplýva na zvýšený výskyt hmly na letisku Žilina.
