Uticaj meteoroloških parametara na koncentraciju SO2 u Obrenovcu, Srbija

In this paper, the impacts of some meteorological parameters on the SO2 concentrations in the City of Obrenovac are presented. The City of Obrenovac is located in the north-west part of Serbia on the banks of the River Sava. The observed source emission, the power plants TENT A and B are situated on the bank of the Sava River in the vicinity of Obrenovac. During the period from January to November 2006, the concentrations of sulfur dioxide in the air at 4 monitoring sites in Obrenovac were measured. It was noticed that the maximal measured daily concentrations of sulfur dioxide ranged from 1 μg m-3 (16th November, 2006) to 98 μg m-3 (29th January 2006) and lie under the maximal allowed concentration value according to the Serbian Law on Environmental Protection. The measured sulfur dioxide concentrations mostly showed characteristics usual for a daily acidification sulfur dioxide cycle, excluding the specificities influenced by the measuring site itself. Sulfur dioxide transport was recorded at increased wind speeds, primarily from the southeast direction. Based on the impact of meteorological parameters on the sulfur dioxide concentration, a validation of the monitoring sites was also performed from the aspect of their representivity.U radu su predstavljeni rezultati monitoringa koncentracije SO2 u vazduhu u Obrenovcu koji se nalazi na severozapadu Srbije na obalama reke Save. Posmatran je uticaj meteoroloških parametara na koncentraciju SO2 emitovanog iz termoelektrana TENT A i B koji se smatraju najvećim izvorima emisije. U periodu od januara do novembra 2006. godine praćene su koncentracije sumpor-dioksida u vazduhu na 4 merna mesta lokalizovana na različitim udaljenostima od izvora emisije. Maksimalne izmerene dnevne koncentracije sumpor-dioksida su se kretale od 1 μg m-3 (16. novembra, 2006) do 24 μg m-3 (29. januara, 2006). Izmerene promene koncentracija sumpor-dioksida uglavnom pokazuju uobičajene karakteristike dnevne acidifikacije ciklusa uz razlike koje potiču od osobenosti mernih mesta. Transport sumpor-dioksida zabeležen je pri pojačanom vetru prvenstveno iz jugoistočnog pravca. Na osnovu korelacionih odnosa između koncentracije sumpor-dioksida i odgovarajućih meteroloških parametara izvršena je karakterizacija mernih mesta u pogledu njihove reprezentativnosti za merenje sumpor-dioksida

Is hail suppression useful in Serbia? – General review and new results

Anthropogenic influence on weather has been increasingly published and discussed in the last decades. Climate changes caused by inadvertent anthropogenic influence are well underway. Hail suppression, which has been proven to have no influence on weather, will be considered in the article. Even though hail suppression as scientifically ungrounded activity seemed to promise certain success several decades ago, it has spread over the whole territory of the Republic of Serbia after abundant experience, when many developed countries have given up on this activity. Reasons will be presented for the senselessness of hail suppression based on the latest research. By processing all hail data from the territory of Serbia in the period from 1967 to 2010, it was found out that the hail trend is rising which is in contrary to expectations and previous claims that hail suppression decreases hail frequency

Preliminary geosite assessment model (gam) and its application on Fruška gora mountain, potential geotourism destination of Serbia

This paper presents a preliminary geosite physical assessment model which has the potential to assist in the sustainable planning and management of natural heritage locations and their transformation into tourism destination. The methodology is based on several existing models and presented through two groups of values – main and additional, which are further divided into indicators and subindicators respectively. The resultant model is a graph that consists of nine fields, into which geosites can be classified as fitting into nine general areas of suitability for tourism in terms of their main (scientific/educational, aesthetic/scenic and protection as market appeal and conservation) and additional values (functional and tourism use as current stage of development). This could prove to be of great help to natural heritage protection and tourism managers, as they could assess the current state of a geosite and thence propose a future path for it

Rainfall erosivity and extreme precipitation in the Pannonian basin

In order to assess the rainfall erosivity in the Pannonian basin, several parameters which describe distribution, concentration and variability of precipitation were used, as well as 9 extreme precipitation indices. The precipitation data is obtained from the European Climate Assessment and Dataset project for the period 1961-2014, for 8 meteorological stations in northern Serbia, 5 in Hungary and 1 in eastern Croatia. The extreme values of precipitation were calculated following the indices developed by the ETCCDI. RclimDex software package was used for indices calculation. Based on statistical analysis and the calculated values, the results have been presented with Geographic Information System (GIS) to point out the most vulnerable parts of the Pannonian basin, with regard to pluvial erosion. This study presents the first result of combined rainfall erosivity and extreme precipitation indices for the investigated area. Results of PCI indicate presence of moderate precipitation concentration (mean value 11.6). Trend analysis of FI (mean value 22.7) and MFI (mean value 70.2) implies a shift from being largely in the low erosivity class, to being completely in the moderate erosivity class in the future, thus indicating an increase in rainfall erosivity for most of the investigated area (except in the northwestern parts). Furthermore, the observed precipitation extremes suggest that both the amount and the intensity of precipitation are increasing. The knowledge about the areas affected by strong soil erosion could lead to introducing effective measures in order to reduce it. Long term analysis of rainfall erosivity is a significant step concerning flood prevention, hazard mitigation, ecosystem services, land use change and agricultural production

Cultural events as part of cultural tourism development. Case study: Sombor and Apatin (Serbia)

Festivals and special events play a significant role in communities' lives because they provide important activities and spending outlets for both locals and visitors, and enhance the tourist image of local communities and their social cohesion. Backgrounds and contents of events are various, but the most attractive ones are those devoted to gastronomy or those that cherish tradition, customs, folklore and handicrafts. The municipalities of Sombor and Apatin are multiethnic regions with authentic folklore and food out of which numerous events of economic and entertainment content emerged. The authors of this study recognized the most significant ten. The research is aimed at determining the attitudes of the local population with regard to the organization, realization and economic importance of cultural events

Natural Disasters vs Hotel Industry Resilience: An Exploratory Study among Hotel Managers from Europe

Hotels, like any other businesses in a given location, can be threatened by natural disasters, usually with significant and long-term consequences. The hotel industry is particularly vulnerable and exposed to the risk of property being physically damaged or completely destroyed. Apart from the physical damage, there is also an accompanying economic risk of the tourism sector suffering as tourists avoid areas affected by a disaster event. Therefore, hotels in the areas prone to natural disasters must ensure they are resilient enough to carry on through the turbulent period until regular business levels return. This study is based on survey responses of 63 hotel managers from the 12 European countries most frequently affected by natural disasters. The study relies on multi-capital predictor based approach and examines hotel resilience to natural disasters. It has been found that managers’ previous experience of a natural disaster, duration of managerial experience, and organizational category and size have a positive effect on hotel resilience. Moreover, hotels must anticipate such situations and continuously drill how to respond efficiently and adapt quickly in order to ensure business sustainability. Practical implications, study limitations and future research recommendations are also discussed
