Abstract. Montenegro so far has been poorly investigated in terms of climate extremes. The aim of this paper was to analyse the extreme ETCCDI (Expert Team on Climate Change Detection and Indices) temperature indices in the Mediterranean region of Montenegro for the period of 1951-2010. Four stations in the coastal area of Montenegro have been analysed: Herceg Novi, Ulcinj, Budva and Bar. Two periods (before 1980 and after 1980) were separately investigated in this study due to a well-known climate shift that occurred in the late 1970s. Seven indices of temperature extremes have been chosen. The trend was analysed using a MannKendall non-parametric test, while the slope was estimated using Sen's slope estimator. A negative trend has been calculated for cold nights and cold days at almost all stations. The most significant positive trends were obtained for warm conditions. The two separately investigated periods have shown contrasting temperature trends.

Abstract. The aim of this paper is to analyse indices of extreme precipitation in Krivošije, Montenegro, the wettest Mediterranean region, from the period 1951-2007 and their relationships with atmospheric circulation using "SynopVis Grosswetterlagen" (SVG) series. Data from two stations were analysed, namely Crkvice (42 • 34 N and 18 • 39 E) and Herceg Novi (42 • 27 N and 18 • 31 E). Four indices of precipitation extremes (SDII, R75p, R95p, R95pTOT) were assessed including number of dry days. The results suggest that the number of days with precipitation decreased. To analyse the relationship between extreme precipitation events and circulation types we have used an efficiency coefficient (E c ). Regarding relation to atmospheric circulation, westerly, southwesterly and northwesterly circulation types with anticyclonic features over Central Europe are more frequent for dry days (days with R < 1.0 mm) and northerly, easterly and southerly types for wet and very wet days (R75p and R95p indices). The types with cyclonic condition over Central Europe show a large proportion of wet and very wet days. Also, activity of Genoa cyclogenesis and orographic influence over a small area are the main reasons for the high precipitation amounts recorded in the Krivošije region (Crkvice).

The main objective of this study is to emphasize the basic climate modificators and types in Montenegro. Rarely could you find such a small area with more climate types and several subtypes and varieties as it is the case here. The most important climate modificators in Montenegro have been discussed in the Part One of the study, such as: mathematical - geographical position, relief dissection, atmospheric circulation and the Adriatic Sea. Atlantic and Mediterranean aquatories and Eurasian landmass play an important part in climate modification in the area of Montenegro. These vast areas represent the source of atmospheric action centres and air masses. In the Part Two of this study, the climate regionalization of Montenegro is given according to the K?ppen criteria, as it has been proved that it gives a good basis for solving several practical and scientific problems.

Abstract. More intense rainfall may cause a range of negative impacts upon society and the environment. In this study we analysed trends in extreme ETCCDI (Expert Team on Climate Change Detection and Indices) rainfall indices in Montenegro for the period between 1951 and 2010. Montenegro has been poorly studied in terms of rainfall extremes, yet it contains the wettest Mediterranean region known as Krivošije. Several indices of precipitation extremes were assessed including the number of dry days and rainfall totals in order to identify trends and possible changes. A spatial pattern relationship between extreme rainfall indices and the North Atlantic Oscillation has also been examined. The results generally suggest that the number of days with precipitation decreased while rainfall intensity increased, particularly in south-western parts of the country. A slight tendency towards intense rainfall events is suggested. The examined rainfall indices and North Atlantic Oscillation over Montenegro seemed to be directly linked to changes in one of the major large-scale circulation modes such as the NAO pattern that is particularly evident during the winter season.

Changes in Europe's Temperature Extreme Values. In environmental researches several concerns on the evolution of temperatures. However, in the last decade we can observe intensification of extreme events, including that of temperatures. The present research investigates the evolution of extreme temperature values scaled at annual scale using frequency analysis on historical data. Three types of extreme temperatures were analyzed: annual minimum and maximum, and highest daily temperature fluctuation on annual scale. The results show both the dynamics of changes and probabilistic laws describing the extreme values, obtaining hazard related to these phenomena. We found risky evolutions in case of maximum annual temperatures, when in 55% of locations the associated hazard value was increasing for long or short time period, and in case of highest daily temperature fluctuation, when in 71% of cases the associated hazard value was increasing for long or short time period.
