Local climate and climate changes during the period between 1961–2019 in the coastal area of Slovenian Istria and Škofije

Glavni namen diplomske naloge je študija spreminjanja podnebja v daljšem časovnem obdobju na obalnem območju Slovenske Istre. Poleg tega pa sem se osredotočil še na trenutno podnebje na obalnem območju Slovenske Istre in Škofij. Tako je diplomsko delo razdeljeno na dva tematska dela. V prvem sem se osredotočil na trenutno podnebje, pri čemer sem uporabil podatke iz dveh glavnih meteoroloških postaj (Portorož Beli Križ in Letališče Portorož) in podatke lastne vremenske postaje na Škofijah. Analiziral sem podatke o temperaturi zraka, padavinah ter hitrosti in smeri vetra. Ugotoviti sem skušal razlike v podnebju, ki se zaradi vpliva reliefa, različne oddaljenosti od morja in drugih dejavnikov pojavljajo na lokalnem nivoju. V drugem delu sem s pomočjo podatkov glavnih meteoroloških postaj Koper Markovec, Portorož Beli Križ in Letališče Portorož ugotavljal trende spreminjanja podnebja v obdobju 1961–2019. Pri analizi sem se naslonil na tri osnovne spremenljivke: temperaturo zraka, količino padavin in Sončevo obsevanje. S pomočjo analize pridobljenih podatkov sem ugotovil, da je na podlagi dolgoročnih homogeniziranih meritev prisotna rast temperature, in sicer približno 0,34 stopinje na desetletje, upad količine padavin na letni ravni za 0,26 % in povečevanje Sončevega obsevanja na letni ravni za 0,1 %.The main purpose of the diploma thesis was to study climate change over a longer period in the coastal part of Slovenian Istria. In addition, I focused on the current climate in the coastal part of Slovenian Istria and Škofije and thus the thesis is divided into two topic sections. In the first section I focused on the current climate and obtained the data from two main meteorological stations (Portorož Beli Križ and Portorož airport) and my own meteorological station located in Škofije. I gathered weather data on temperature, precipitation, and wind speed and direction. I observed the differences in the local climate which occur on short distances due to the diversity of relief, different distances from the sea and other factors. In the second section I studied the trends of climate change over the period 1961 - 2019 based on the data obtained from the main meteorological stations located in Koper – Markovec, Portorož Beli Križ and Portorož airport. The analysis included three core variables – temperature, precipitation amount and solar radiation, which are measured at the main meteorological stations. The analysis of the data based on long-term measurements that were homogenized showed an increase in temperature for 0,34 degree Celsius/decade, a decrease in the amount of precipitation for 0,26% and an increase in solar radiation for 0,1%
