20.500.12556/RUL-174778 Analiza mestnega toplotnega otoka Ljubljane Analysis of Ljubljana's urban heat island Diplomsko delo obravnava vpliv vremenskih dejavnikov na intenzivnost mestnega toplotnega otoka (MTO) v Ljubljani v obdobju 2020–2022. MTO se kaže kot višja temperatura v mestnem središču v primerjavi z njegovo podeželsko okolico, pri čemer se pojav najizraziteje kaže ponoči in v jutranjih urah. Namen raziskave je bil ugotoviti, kako na intenzivnost MTO vplivajo megla, padavine in veter. Uporabljeni so bili podatki več meteoroloških postaj, ki so bili analizirani s pomočjo spletne aplikacije preglednice Google, pri čemer smo izračunavali temperaturne razlike med mestnim in obrobnim območjem. S pregledom literature smo ugotovili, da je intenziteta MTO v Ljubljani nekje med 2,5 in 7 °C. Rezultati so pokazali, da megla in padavine močno vplivajo na intenzivnost MTO, saj je v primeru megle ta znašala 0,7 °C, v primeru padavin pa le še 0,3 °C, medtem ko veter, ker je v Ljubljani velik del leta prevladuje brezveterje in prevladujejo šibki vetrovi, ni imel odločilnega vpliva, saj razlike med mestom in obrobjem praktično ni bilo. Ugotovitve prispevajo k boljšemu razumevanju mikroklime v urbanih okoljih in so lahko osnova za načrtovanje prilagoditvenih ukrepov v prihodnosti. The thesis addresses the influence of weather factors on the intensity of the urban heat island (UHI) in Ljubljana in the period 2020–2022. The UHI manifests as higher temperatures in the city centre compared to its rural surroundings, with the phenomenon being most pronounced during the night and early morning hours. The aim of the research was to determine how fog, precipitation, and wind affect the intensity of the UHI. Data from several meteorological stations were used and analysed using the online application Google Sheets, calculating temperature differences between the city and its outskirts. A literature review found that the intensity of the UHI in Ljubljana ranges between approximately 2.5 °C and 7 °C. The results showed that fog and precipitation significantly influence the UHI intensity, with the difference being 0.7 °C in foggy conditions and only 0.3 °C during precipitation. Wind, on the other hand, had no decisive impact due to a large portion of calm conditions and prevailing weak winds in Ljubljana, resulting in practically no temperature difference between the city and its outskirts. The findings contribute to a better understanding of the microclimate in urban environments and can serve as a basis for planning adaptation measures in the future.
