Opis:
The present paper concentrates on the basic features of an annual precipitation course (monthly, seasonal and annual sums) registered between 1861-2000. The paper also defines an amount of precipitation sums’ deviations from the many years’ average, factor of monthly precipitation sums’ changeability and trends of their changes. The characteristics of the annual precipitation sums in an annual course allow to define which months, seasons and half-years were characterized by more intensive changeability and discover if there was recorded a considerable asymmetry between the particular months, seasons and half-years and what were the reasons of the asymmetry.
Celem pracy było określenie trendów zmian wielkości opadów i odchylenie od średniej wieloletniej w okresie 1861-2000 oraz ocena, które miesiące, pory roku i półrocza charakteryzowały się większą zmiennością, czy wystąpiła duża asymetria między poszczególnymi miesiącami, porami roku i półroczami i jakie były jej przyczyny. Na podstawie przeprowadzonej analizy stwierdzono, że przebieg roczny sum opadów w Lęborku charakteryzował się dużą zmiennością. Wynika ona z wahań oddziaływania cyrkulacji znad Oceanu Atlantyckie-go, Morza Bałtyckiego i obszaru kontynentalnego oraz uwarunkowań lokalnych, między innymi położenia w pradolinie Redy-Łeby. Częste występowanie maksimum opadów nie tylko w lipcu, ale również w sierpniu, wrześniu i październiku i niskie sumy w lutym, marcu i kwietniu świadczą o dużym wpływie Morza Bałtyckiego. Wiosną i wczesnym latem jest on ochładzający i powoduje obniżenie sum opadów, natomiast od lipca do listopada wzrost kontrastów na granicy ląd-morze przyczynia się do znacznego ich wzrostu, dlatego jesień charakteryzuje się wysokimi sumami opadów (w 84% lat były one wyższe od sum wiosennych i zimowych oraz w 37% od sum letnich). Zmienność opadów jest również widoczna w wielkości odchyleń od średniej wieloletniej. Wszystkie miesiące charakteryzowały się bardzo dużymi wahaniami (szczególnie październik), podobnie sumy opadów w porach roku, półroczach i roku. Tak duże wahania świadczą o występowaniu na przemian okresów z nadmiarem lub niedoborem sum opadów, czyli każ-dy miesiąc, pora roku, półrocze lub rok w jednym roku mogły być suche, a w następnym wilgotne. Największe odchylenie standardowe sum opadów wystąpiło od lipca do października, wśród pór roku były to lato i jesień, zaś w półroczu ciepłym odchylenie było większe niż w chłodnym. Współczynnik zmienności był największy w październiku, większy wiosną niż latem, wskazuje on również na większą zmienność opadów w półroczu chłodnym niż ciepłym. Trend wzrostu sum opadów wystąpił we wszystkich miesiącach, porach roku i półroczach. Największym wzrostem charakteryzowały się: miesiące – październik (0,11 mm/rok), grudzień (0,09 mm/rok), styczeń (0,09 mm/rok) i czerwiec (0,08 mm/rok); pory roku – jesień (0,23 mm/rok) i zima (0,23 mm/rok), natomiast w przypadku półroczy, w obu tendencja wzrostu była duża: w półroczu ciepłym – 0,41 mm/rok, w półroczu chłodnym – 0,34 mm/rok. W całym wieloleciu wystąpił trend wzrostu rocznych sum opadów – 0,77 mm/rok.

Opis:
Air temperature and precipitation conditions in the Kaffiøyra region in the summer season (21st July–31st August) for the period of 1975–2010 are described: 1) on the basis of data gathered in 18 expeditions during which meteorological measurements were done, and 2) on the basis of complete series of data combining both original and reconstructed data. The latter ones were obtained using data from Ny Ålesund meteorological station, which are strongly correlated with the data from Kaffiøyra. Seasonal statistics presented for air temperature and precipitation based on these two sets of data reveal only slight changes. Temperature parameters (daily mean, maximum and minimum) for summer in Kaffiøyra in the study period (1975–2010) show upward trends, which are, however, statistically significant only for the daily mean. On the other hand, precipitation totals in the study period reveal a downward trend, but not statistically significant. Such thermal-precipitation behaviour in the study part of Spitsbergen in general terms is similar to those in other parts of Spitsbergen.

Opis:
Climate change is determined as a severe threat to water resource availability in Semi-Arid Areas. Therefore, it is crucial to examine the drought trends to develop and sustain water resources. This study evaluates the effects of climate change in Jordan by investigating the long-term precipitation trends in the Amman Zarqa Basin over the water from 1971 to 2016. Daily precipitation data were gathered to analyze different rainfall stations over and around the basin. The standardized precipitation index (SPI) variations were investigated at monthly intervals. Control charts, hypothesis testing, T-test, differences of variances, and trend analysis were used to determine climatic trends. The analysis results showed that 2003 marks an acceleration point in the precipitation decrease rate; therefore, the SPI showed a decrease and a high DI for the area in the tested year 2005 and 2010 to be a mild drought in the following years. Additionally, a change in the precipitation pattern was observed as seasonal precipitation contribution varied for the pre-2003 period compared to the post-2003 period. The SPI results show that 1995 reflects the higher drought periods, and the following years showed mild drought events; nevertheless, the year 2016 displayed lower drought events, reflecting wet events.

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.

Opis:
Extreme rainfall is one of the environmental hazards with disastrous effects on the human environment. Water resources management is very vulnerable to any changes in rainfall intensities. A spatiotemporal analysis is essential for study the impact of climate change and variability on extreme rainfall. In this study, daily rainfall data for 36 meteorological stations in Iraq during 1981–2017 were used to investigate the spatiotemporal pattern of 10 extreme rainfall indices using RClimDex package. These indices were classified into two categories: rainfall total (PRCPTOT, SDII, R95p, R99p, RX1day, and RX5day) and rainfall days (CDD, CWD, R10, and R20). Depending on the mean annual precipitation data, the study area was divided into three climatic zones to examine the time series features of those 10 indices. Results showed a tendency to increase in precipitation toward the northwestern part of Iraq, and more than 70% of stations achieved a positive trend for most indices. The most frequent negative trend appeared in eight stations distributed in the western and southern parts of Iraq, namely (Heet, Haditha, Anah, Rutba, Qaim, Nukheb, Najaf, and Fao). A significant positive trend appeared obviously in PRCPTOT and R95p with a rate of 0.1–4.6 and 0.5–2.7 mm per year, respectively. Additionally, the least trend increasing appeared in all precipitation days indices specifically in R10 and R20. Time series analyses revealed a positive trend in all regions under study, except SDII in the southern region. The most significant rate of change was noticed in regions one and two (northern and middle parts of Iraq), particularly for PRCPTOT and R95p 3.26 and 2.45 mm per day, respectively. Only the northern and eastern regions of Iraq experienced a high probability of significant extreme rainfall.

Opis:
The purpose of the paper is to analyze the spatial variability of precipitation in Poland in the years 1981–2010. The average annual rainfall was 607 mm. Precipitation in Poland is characterized by high spatial and temporal variability. The lowest annual precipitation was recorded in the central part of the country, where they equaled 500 mm. The highest annual precipitation totals were determined in the south, equaling 970 mm. The average precipitation in the summer half-year is 382 mm (63% of the annual total). On the basis of data from 53 climate stations, maps were made of the spatial distribution of precipitation for the period of the year and winter and summer half-year. The kriging method was used to map rainfall distribution in Poland. In the case study, cross-validation was used to compare the prediction performances of three periods. Kriging, with exponential type of semivariogram, gave the best performance in the statistical sense. Their application is justices especially in areas where landform is very complex. In accordance with the assumptions, the mean prediction error (ME), mean standardized prediction error (MSE), and root mean-square standardized prediction error (RMSSE) values are approximately zero, and root-mean-square prediction error (RMSE) and average standard error (ASE) reach values well below 100.

The purpose of the work is to characterise pluvial conditions in central-eastern Poland from the beginning of the 21st century (2001-2020). The analysis involved seven meteorological stations of the Institute of Meteorology and Water Management - National Research Institute (IMGW-PIB): Białowieża, Legionowo, Pułtusk, Siedlce, Szepietowo, Terespol and Warsaw. The work contains the analysis of the annual and seasonal atmospheric precipitation pattern (summer, winter, spring and autumn) and its temporal and spatial variation throughout a 20-year period. Moreover, the percentage share of precipitation in each season in the annual sum was calculated. In order to analyse precipitation patterns in the study period, the Innovative Trend Analysis (ITA) was applied. The average long-term annual atmospheric precipitation sum ranged from 557 mm at Terespol to 653 mm at Białowieża. The highest seasonal precipitation sum in the studied region was recorded for the summer (218 mm) whereas in spring and autumn, precipitation stayed at a similar level and amounted to 130 and 131 mm, respectively. The lowest precipitation was recorded in winter (109 mm). The highest percentage share of the atmospheric precipitation sum was associated with summer rainfall (from 35 to 38%), whereas the lowest in winter (from 18 to 20%). Comparisons of 2001-2010 and 2011-2020 decades revealed a decline in the share of summer precipitation in the annual sum at most of the stations, and an increase in the share of winter precipitation. The ITA demonstrated that the most significant trends in precipitation change occurred in summer and winter and the directions of the trends were different for each station.

Opis:
Heavy and/or long-lasting precipitation events in the Tatra Mountains and their northern foothills may cause floods that propagate downstream in the Vistula River and inundate large areas of Poland. In a warmer climate, future precipitation extremes could be higher than they are today, hence the flood risk potential is likely to grow. Therefore, assessment of these future changes and adaptation to changes in flood risk are of considerable interest and importance. In this study, seven global climate models were used to get insight into a range of changes in the characteristics of mean and heavy precipitation: this was done for two climate scenarios – A1B and A2 of the SRES family. With the help of the so-called delta-change method and based on responses from global climate models, projections were made for 11 precipitation stations in the region. Analyses were made of various indices, such as annual totals, maximum 24 h, 5-day; 10-day, monthly maximum sums of precipitation and also numbers of days with intense precipitation equal or above the thresholds of 30 and 50 mm per day. It was found that all GCM models under examination projected an increase in mean annual precipitation totals as well as in heavy precipitation in the future time horizon studied here (2080-2100).

Opis:
The present research has aimed at estimating the water requirements of grapevine in 2016-2050 in the Bydgoszcz region based on the anticipated temperature changes. . The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the grapevine have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016- 2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In the 2016-2050 period in the Bydgoszcz region, in the light of the anticipated temperature change scenarios, one can expect increased grapevine water requirements. Determined with the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for the grapevine from 440 mm to 576 mm (by 136 mm, namely by 31 %). The optimal precipitation trend equations demonstrate that in the reference period (1981-2015), calculated with the Kemmer and Schulz, the optimal annual precipitation was increasing in grapevine in each pentad by 2.2-2.6 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad in a much greater range (8.0-8.9 mm). In the summer period (May-September) determined by Kemmer and Schulz, the total precipitation optimal for the grapevine, expressing the water requirements, in 2016-2050 will increase by 68 mm.

Opis:
Daily precipitation data from 40 stations are used to investigate the temporal variability of precipitation extremes in Estonia. The period covered is 1961–2008, characterized by a uniformity of observational practice. Precipitation extremes are quantified by yearly and seasonal values of two different parameters: daycount indices based on 95th and 99th percentile thresholds. Trend significance was assessed with the Mann-Kendall test. Results show that the frequency of both indices has increased. No significant negative trends were found. An increase of 15.8 events over the 99th percentile per decade was observed for Estonia. The indices selected for this study may be called ‘soft’ climate extremes, but the number of such events is large enough to allow for meaningful trend analysis in a roughly half-century long time series.

Opis:
This study provides an assessment of the current and future changes (in terms of both direction and value) in air temperature, precipitation, snow, wind and their extremes over the territory of Belarus using information from 42 meteorological stations and 92 regional circulation model (RCM) simulations with the highest available horizontal resolution (EUR-11). Three representative concentration pathway scenarios, namely, RCP2.6, RCP4.5 and RCP8.5, are considered. Results demonstrate that in recent decades, temperature has increased over the territory of Belarus by 1.3°C, with the largest increase occurring during the cold season (2.1-2.3°C). Ensemble scenarios project further increases in air temperature in the current century by +0.5-1.5°C, +2.8°C, and +5.2°C under the RCP2.6, RCP4.5 and RCP8.5 scenarios, with the largest increase during the cold season under the RCP8.5 scenario. The annual means were observed to increase (insignificantly) by 5-7% and the summer precipitation extremes exhibited a 20-25% growth in recent decades. Moreover, dry conditions have intensified in Belarus, particularly during the growing season. Further increases in precipitation of 10-15% across Belarus are projected to occur in all seasons under the RCP4.5 and RCP8.5 scenarios. Simulation models predict greater increases in single day rainfall events compared to their multiday precipitation counterparts. The greatest increases in maximal dry period length (by 1-2) are expected to occur in summer and autumn. The models project the general decrease in snowfall across Belarus to continue into the current century, with a reduction in snow precipitation days of 10-30 days. Despite the reduced wind strength (by 0.9-1.0 m·s -1 ) since the 1970s over the territory of Belarus, the ensemble model reveals slight nonsignificant changes in seasonal and annual wind strengths until the end of the century. Significant changes of 1-3 days under varying directions of the wind regime were observed for days with a strong breeze and storms.

The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the apple tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In the 2016-2050 period in the Bydgoszcz region, in the light of the temperature change scenarios, one could expect increased apple-tree water requirements. Determined with the Kemmer and Schulz method, the required annual (January-December) optimal precipitation will increase for the apple tree from 681 mm to 849 mm (by 168 mm, namely by 25 %). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated with the Kemmer and Schulz numbers, the optimal annual precipitation for the apple tree was increasing in each pentad by 5.8-6.3 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad in a much greater range; from 8.5 to 9.6 mm. In the summer period (May-September) determined by Kemmer and Schulz, the optimal precipitation, expressing the water requirements, for the apple tree in 2016-2050 will increase by 84 mm.

Determined according to the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for peach from 486 mm to 612 mm (by 126 mm, which accounts for 26%). The optimal precipitation time variation trend equations show that in the reference period (1981-2015), calculated based on the Kemmer and Schulz number, the optimal annual precipitation was increasing in the peach tree in each pentad by 4.4-4.8 mm. In the forecast period (2016-2050) the water requirements of the peach tree will be increasing in each pentad in a greater range - from 6.4 to 7.2 mm. In the summer period (May-September) determined by Kemmer and Schulz, expressing water requirements, the total precipitation optimal for the peach tree in 2016-2050 will increase by 63 mm.

Opis:
The aim of the present research has been an attempt at evaluating the water requirements of plum trees over 2016-2050 in the Bydgoszcz region drawing on the forecast changes in temperature. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the plum tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In 2016-2050 in the Bydgoszcz region, in the light of the forecast temperature change scenarios, one should expect an increase in the water requirements of the plum tree. The annual (January-December) optimal total precipitation determined according to the Kemmer and Schulz method will increase for the plum tree from 712 mm to 807 mm (by 95 mm, which accounts for 13%). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated, drawing on the Kemmer and Schulz number, the optimal annual precipitation was increasing in the plum tree in each pentad by 7.1-7.5 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad within a much smaller range, from 2.6 to 3.0 mm. In the summer period (May-September) determined by Kemmer and Schulz, the total precipitation optimal for the plum tree, expressing water requirements, in 2016-2050 will increase by 47 mm.

The aim of the present research has been an attempt at evaluating the water requirements of pear trees over 2016-2050 in the Bydgoszcz region drawing on the forecast changes in temperature. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the pear tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In the period 2016-2050 in the Bydgoszcz region, in the light of the temperature change scenarios made, one should expect an increase in the water requirements of the pear tree. Determined with the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for the pear tree from 624 mm to 771 mm (by 147 mm, namely by 24 %). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated with the Kemmer and Schulz numbers, the optimal annual precipitation was increasing in the pear tree in each pentad by 5.1-5.5 mm. In the forecast period (2016-2050) the water requirements will increase, on the other hand, in each pentad within a much greater range (7.5-8.4 mm). In, determined by Kemmer and Schulz, summer period (May-September), the total precipitation, expressing water requirements, optimal for the pear tree in 2016-2050 will increase by 73 mm.
