Opis:
The development of climate change is evaluated on the basis of trends in a long-term time series (1951-2018) of individual climatic elements by comparing values from individual years with the normal period in climatology of 1961-1990. The aim of the article is to present the manifestations of climate change in Slovakia (since its inception) according to selected indicators: (1) average annual air temperature, (2) soil temperature, (3) total atmospheric precipitation and (4) drought index over the last decade. The data presented in the article were obtained from public reports on the state of the environment in the Slovakia and other related documents. Slovakia, during the years 1881-2018, underwent significant changes in all monitored climatic elements. The most significant changes were in 2017 and 2018.
Postęp zmian klimatu ocenia się na podstawie trendów w długoterminowych szeregach czasowych (1951-2018) poszczególnych elementów klimatu, na podstawie porównania wartości z wielu lat, z normalnym okresem w klimatologii 1961-1990. Celem artykułu jest przedstawienie przejawów zmian klimatycznych na Słowacji (od ich powstania) według wybranych wskaźników: (1) średnia roczna temperatura powietrza, (2) temperatura gleby, (3) suma opadów atmosferycznych, (4) susza indeks w ciągu ostatniej dekady. Dane przedstawione w artykule pochodzą z publicznych raportów na temat stanu środowiska w Republice Słowackiej i innych powiązanych dokumentów. W Słowacji w latach 1881-2018 znaczącym zmianom uległy wszystkie monitorowane elementy klimatyczne. Największe zmiany zaobserwowano w latach 2017 i 2018 roku.

Opis:
The relationship between tree-ring growth and climate in Quercus brantii, a widespread and dominant tree species in Zagros-Anti-Taurus Mountains, was investigated by both age-dependent and independent approaches. A total number of 118 trees were sampled in a region where severe Mediterranean climate prevailed. An overall chronology plus three age-dependent chronologies of <80, 80 to 160 and >160 years old were constructed to study growth-climate relationships based on an integrated approach of principle component stepwise regression followed by complementary response function analysis. High age heterogeneity of overall chronology diminished its climatic signals and growth priority was significantly presented in the models. Biennial and triennial precipitation variations were highly related with annual tree ring growth of young and old oaks, respectively. However, hot growing season negatively affected all age-dependent chronology indices. By increasing tree ages the negative effects of warm autumn prior to growth decreased and late winter fall became a limiting climatic factor in old trees. Results of response function analysis also revealed that all oak trees from each age classes were sensitive to increasing April temperature. It’s anticipated that, regarding the trends of late frost, this species will face with many challenges in this region and similar areas.

Opis:
In this paper, the long-term variability of global solar radiation in the agricultural area of Lower Silesia is analyzed based on a 56-year long (1961-2016) measurement series recorded at the Agro- and Hydro-meteorological Wrocław-Swojec Observatory (SW Poland). Yearly and monthly global radiation sums with their extreme and mean values were compared with radiation data from Warsaw (Central Poland) and Potsdam (East Germany). The dynamics of variability between consecutive months, seasons and years was also taken into account. The conducted positive trends show a significant increase in the investigated global radiation sums for Lower Silesia and also for Central Poland and the eastern part of Germany. The trends are strongly related to long-term macro-circulation changes in the North Hemisphere, particularly with the phases and sub-phases of the North Atlantic Oscillation (NAO). The relations between the investigated values of global solar radiation and these macro-circulation patterns are very complicated and they very often have an asynchronous character. The first, juvenile stage of the NAO positive phase (the 1970s and 1980s), when annual sums of global solar radiation in Wrocław-Swojec reached only the average level of about 3700 MJ·m-2 and warm half-year about 2800 MJ·m-2 respectively, was cloudy and rainy. This period was distinctly different than the advanced stage of one (the 1990’s and later years) with bigger sunshine duration and smaller annual precipitation, when the adequate radiation sums amount to 3 900-4000 MJ·m-2 and 3 000-3 100 MJ·m-2 respectively.

Opis:
Studies associated with climate change and variability are of great importance at both the global and local scale in the global climate crisis. In this study, change-point detection and trend analysis were carried out on mean, maximum, minimum air temperatures and total precipitation based on monthly, seasonal and annual scale in Bartın province located in the western Black Sea Region of Turkey. For this aim, 4-different homogeneity tests (von Neumann test, Pettitt test, Buishand range test and standard normal homogeneity test) for changepoint detection, Modified Mann–Kendall test and Şen’s innovative trend test for trend analysis, and Sen’s slope test for the magnitude estimation of trends were used. According to the test results, the summer temperatures in particular show increasing trends at the 0.001 significance level. Mean maximum temperature in August, mean minimum temperature in June and August, and mean temperature in July and August are in increasing trend at the 0.001 significance level. Over a 51 year period (1965–2015) in Bartın province, the highest rate of change per decade in air temperatures is in August (0.55°C for Tmax, 0.46°C for Tmin and 0.43°C for Tmean) based on Sen’s slope. However, the study showed that apart from October precipitation, there is no significant trend in monthly, seasonal and annual precipitation in Bartın. Increasing trends in mentioned climate variables are also visually very clear and strong in Şen’s innovative trend method, and they comply with the statistical results. As a result, the study revealed some evidence that temperatures will increase in the future in Bartın and its environs.
