Abstract
V posledných desaťročiach sa v strednej Európe čoraz častejšie diskutuje o vzťahu medzi klimatickou zmenou a zvyšujúcou sa intenzitou konvektívnych búrok. Pre letecké prevádzky predstavujú búrky významné bezpečnostné riziko, najmä v blízkosti letísk. Táto problematika nadobúda na význame v kontexte globálneho otepľovania, ktoré ovplyvňuje energetickú bilanciu atmosféry a podmienky pre vznik silných konvekčných javov.
Cieľom tejto práce je analyzovať, či sa v dôsledku klimatickej zmeny prejavuje zmena intenzity búrok v oblasti Moravy a to prostredníctvom hodnotenia vývoja kľúčových konvektívnych indexov v posledných dekádach. Analýza bola založená na aerologických meraniach z meteorologickej stanice v Prostějove, ktoré boli doplnené o správy METAR z letiska Ostrava Mošnov.
Z vybraných dní s búrkovou činnosťou boli vypočítané hodnoty konvektívnych parametrov, najmä CAPE a BWD, a ich dlhodobý trend bol štatisticky vyhodnotený. Výsledky ukazujú zvýšenie mediánovej hodnoty indexu CAPE, čo naznačuje rastúci potenciál atmosféry pre vznik silnejšej konvekcie. Naopak, v prípade indexu BWD (Bulk Wind Difference) nebola zistená výrazná dlhodobá zmena.
Zistenia poukazujú na možný nárast intenzity búrok v regióne Ostravy v súvislosti s klimatickou zmenou, čo podčiarkuje potrebu prispôsobenia leteckých postupov a zlepšenia predpovedných modelov. Práca tak prispieva k zvýšeniu povedomia o meteorologických rizikách a k podpore bezpečnosti leteckej prevádzky.
In recent decades, the relationship between climate change and the increasing intensity of convective storms has been increasingly discussed in Central Europe. For aviation operations, thunderstorms represent a significant safety risk, particularly in the vicinity of airports. This issue is gaining importance in the context of global warming, which affects the atmospheric energy balance and the conditions for the development of strong convective phenomena. The aim of this thesis is to analyze whether climate change manifests itself in a change in storm intensity in the Moravia region by evaluating the development of key convective indices over the past decades. The analysis was based on aerological measurements from the meteorological station in Prostějov, supplemented by METAR reports from OstravaMošnov Airport. From selected days with thunderstorm activity, values of convective parameters, particularly CAPE and BWD, were calculated and their long-term trends were statistically evaluated. The results show an increase in the median value of the CAPE index, indicating a growing potential of the atmosphere for the formation of stronger convection. In contrast, for the BWD (Bulk Wind Difference) index, no significant long-term change was observed. The findings indicate a possible increase in storm intensity in the Ostrava region in connection with climate change, highlighting the need to adapt aviation procedures and improve forecasting models. The thesis thus contributes to raising awareness of meteorological risks and enhancing aviation safety.
