Item type:Publication, Investigating relationships between PM10 and Climatic parameters using PCA in the three largest urban areas in North Macedonia(2025-06-26) ;Manevska, Emilija; ; ; Kuzmanoski, ArseThis study applies Principal Component Analysis (PCA) to evaluate how meteorological factors influence PM10 pollution in Skopje, Kumanovo and Bitola from 2012 to 2020. PCA reduces data complexity while identifying key weather variables that impact air pollution levels. Findings indicate that temperature and wind speed have the strongest negative correlation with PM10 concentrations, meaning lower temperatures and weaker winds are linked to higher pollution levels. These conditions limit pollutant dispersion, leading to worse air quality. Humidity and precipitation have mixed effects—humidity can promote both the removal and formation of pollutants, while precipitation aids in PM10 reduction through wet season, depending on intensity and duration. The extracted principal components explain a significant portion of pollution variability, highlighting the dominant meteorological influences on air quality trends. By clarifying these relationships, PCA enhances the understanding of air pollution dynamics in the three largest urban areas in North Macedonia. This analysis provides valuable insights for air quality management in North Macedonia. By identifying the key meteorological drivers of pollution, policymakers can develop more targeted and effective strategies to mitigate PM10 levels and improve public health. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, ANTHROPOGENIC PRESSURES ON AIR QUALITY IN THE SKOPJE AGGLOMERATION(Macedonian Geographical Society, 2025-02-01) ;Manevska, Emilija; ; ; Kuzmanoski, ArseAir pollution in the Skopje agglomeration represents a decades-long, complex problem, which requires a profound approach. The expansion of the urban space, which has been especially intensified in the last decade, as well as other socio-economic factors in the capital, have led to an additional serious threat to the health of the population through air pollution. This paper aims to analyze the socio-economic characteristics of the Skopje agglomeration, which exert a great pressure on the environment, and are reflected with the greatest consequences on the air quality in the agglomeration. The location for the research was determined due to the fact that the largest population of residents from the Republic of North Macedonia is concentrated in the Skopje agglomeration and it has high concentrations of air pollutants from all types of pollution sources and pollutants, where the concentration of the population and industrial facilities cause a threat to the quality of the basic components of the environment. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Unveiling Torrential Flood Dynamics: A Comprehensive Study of Spatio-Temporal Patterns in the Šumadija Region, Serbia(MDPI AG, 2024-03-29) ;Petrović, Ana M. ;Leščešen, Igor<jats:p>This paper presents a comprehensive analysis of flood frequency and a spatio-temporal characterization of historical torrential floods in the Šumadija region using water discharge datasets and documented events. A chronology of 344 recorded torrential flood events, spanning from 1929 to 2020, illustrates the region’s vulnerability, with a death toll exceeding 43. The study defines the intra-annual primary and secondary peaks of torrential flood occurrences and explains their spatial distribution. Furthermore, the identification of suitable probability distribution functions underscores the necessity of tailored approaches for effective flood risk management in this diverse geographical environment. The study employed Flood Frequency Analysis (FFA) and goodness-of-fit tests, including the Kolmogorov–Smirnov (K-S) and Cramér–von Mises (CvM) tests, to assess the frequency and magnitude of flood events and evaluate diverse distribution functions. The main results include the identification of suitable probability distribution functions for each river within the region, emphasizing the need for tailored approaches in flood risk management. Additionally, discharge values for various return periods offer crucial insights for informed decision-making in flood risk management and infrastructure planning.</jats:p> - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Characteristics of annual and seasonal precipitation in North Macedonia: change analysis and correlation with the North Atlantic Oscillation (1951–2010)(Idojaras, 2024); ;Hall, Julia; ;Arse Kuzmanoski, Ana M. PetrovićManevska, Emilija<jats:p>Studying the spatiotemporal precipitation characteristics in North Macedonia (1951–2010) is important as no spatially concurrent precipitation changes across the Balkan Peninsula have been identified. North Macedonia lies at the intersection between Mediterranean and continental climate zones and an improved understanding might help to better understand the regional precipitation patterns. The analysis shows a spatially consistent, high inter-annual variability, which makes trend detection difficult. Statistically significant decreasing trends were only found in seasonal precipitation at three stations. Changes in all other precipitation series were non-significant. Trends in winter, spring, and at annual scale are generally decreasing, whereas in summer are increasing. To better understand possible mechanisms behind the observed variability and change, correlations with the North Atlantic Ocsillation (NAO) were assessed. Significant and regionally concurrent correlations were detected. A strong correlation of the previous winter NAO-index with spring precipitation was found, which is valuable information for anticipatory water resources management in the region.</jats:p>
