Opis:: This paper presents the results of the studies of metal content in precipitation water in 2013, recorded at measuring points within Lubelskie and Lubuskie Voivodeships. It provides a detailed description of the method of collecting and analysing water samples in respect of light- and heavy-metal determination. Based on the results, a general assessment was made of the condition of the environment in the areas in question. Also, the sources of pollution in wet precipitation, and the effects of their introduction into the environment, were determined. It was found that the main pollution elements of precipitation water were linked to anthropogenic sources. The study also established that precipitation water, especially in the sparsely industrialised Włodawa region in the Lubelskie Voivodeship, had generally low pollution levels. It was also noted that in 2013, due to low total precipitation, the environmental impact of metal content was lower than in the preceding years.

Opis:: The study aims at investigating the so-called precipitation gradient, i.e. changes in the amount of precipitation depending on the elevation above sea level in the mountainous areas of southern Poland. The gradient value is specified in mm of precipitation per 100 m elevation difference. Experimental studies were conducted in two small Beskids valleys, the Barbara stream valley and the Wilkówka stream valley. Five rain gauges were installed across land elevation profiles of said valleys. Decade precipitation amounts during the summer and autumn of 2015 were recorded. The precipitation data of the national environmental monitoring from the nearby mountain and foothill weather stations from 2014–2018 were also used for the analyses. The data analyses demonstrated a large spatial variation in the amount of precipitation. The occurrence of a varied gradient, and even inverse situations i.e. greater precipitation at the locations with lower elevation, were recorded. The precipitation gradient was differentiated, particularly by the terrain exposition relative to the dominant inflow direction of moist air masses, as well as the spatial arrangement of mountain ranges.

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.

Tematy:: relative vorticity
SSTA
precipitation anomaly
Opis:: Monthly relative vorticity and the relative vorticity anomaly at pressure level 850 hPa are computed to study circulation over Southeast Asia associated with the rainfall over Thailand. Monthly mean rainfall is averaged during the years 1979 to 2013 over Thailand to study the trends of rainfall and to analyze the difference between the SSTA in a dry year (1992) and a wet year (1999), and the precipitation anomaly. Rotation of the relative vorticity over Thailand during the rainy season in 1999 is supported by the westerly wind from the Indian Ocean. Relative vorticity over Thailand in October to December are brought by the wind from the east toward the west of the South China Sea. The positive value of relative vorticity in 1992 is less than in 1999. This is consistent with the precipitation anomalies in 1992 and 1999. Clearly, the rainfall and precipitation anomaly over Thailand in wet year 1992 and dry year 1999 are consistent with the relative vorticity at pressure level 850 hPa. Both years are also associated with the SSTA. It can be concluded that the large amounts of rainfall over Thailand are associated with the positive values of relative vorticity at pressure level 850 hPa and SSTA over Southeast Asia. The daily relative vorticity at pressure level 850 hPa and SSTA over Southeast Asia during Typhoon Linda is analyzed in the research. The positive value of relative vorticity is consistent with circulation during Typhoon Linda which is brought by winds from the South China Sea, and the SSTA is also unusual over the Gulf of Thailand and the Andaman Sea. These are the causes of violent storms in Thailand during Typhoon Linda.

Opis:: This elaboration was based on yields of nine medium-early cultivars of potato grown in Karżniczka station belonging to COBORU(Research Centre for Cultivar Testing) and on monthly precipitation sums during the growing season (April – August). For each of the cultivars separately in subsequent years and for precipitation sums in particular months of the growing season (IV–VII) polynomial regression models of precipitation – cultivar’s yield – were calculated. At the beginning of the growing season the yield of medium-early cultivars of potato was negatively correlated with monthly precipitation sums, while in the final stage of vegetation – this correlation was positive. The lowest yield of Stasia cultivar was noted with monthly precipitation sum of 34–38 mm in April, Tajfun cultivar with May precipitation from 100 to 120 mm, Finezja and Jurek cultivars with monthly June precipitation of 120 mm. Whereas maximum yield of Cekin and Jurek cultivars was noted with August precipitation of about 100 mm.

Opis:: The standardized precipitation index (SPI), standardized reference evapotranspiration index (SEI) and standardized climatic water balance index (SCWBI) were used to analyze moisture conditions in the vegetation seasons of 1954–1995 in Łódź. SPI and SEI were calculated on the assumption that empirical monthly precipitation sums and monthly sums of reference evapotraspiration are gamma distributed. Because monthly sums of climatic water balance are normally distributed, they required standardization to SCWBI. The aim of study was to compare those three indexes (SPI SEI and SCWBI) for years 1954–1995 in Łódź.

Opis:: Runoff water is an important medium transporting various types of pollution originating from the atmosphere and washed out from roofing materials. The study presents a quality assessment of runoff from different roofs in the context of trace metal concentrations. The analysed rooftops were covered with copper, tar paper and ceramic tile. The quality of the rain water collected at the same time satisfies the demands of the first grade of cleanliness according to (Journal of Laws, 2016 item1187). The highest content of copper was leached from the copper roof, containing 10.23 mg∙dm^-3. In the case of zinc, the highest concentration of 15.52 mg∙dm^-3 was present in the runoff from the roof covered with thermally bonded tar paper. The amount of trace metals in the ceramic roof runoff was the lowest and only for zinc slightly exceeded 1.47 mg∙dm^-3 – the value determined for II class of purity. In the paper, the different levels of heavy metals leaching from different roofing materials have been confirmed.

Opis:: The aim of the experiment presented in this paper is to assess the relationship between the height and diameter increase rate and the thermal conditions and precipitation during its growth. The experiment was carried out in the Agro- and Hydrometeorology Observatory of the Wrocław University of Environmental and Life Sciences in 2013–2015. The height and diameter measurement was made each time on the same 43 plants, randomly selected at the stage of setting up the experiment in 2012 and specially marked. Plants included in further analyses were divided into 5 classes and the classification criterion was their height in the 3rd year of cultivation. Initially, an analysis of relationships of selected morphological parameters of Scots pine was carried out, i.e. of the heights and diameters against the changing weather conditions, i.e. precipitations and air temperatures. Subsequently, an effect of the thermal conditions and the amount of precipitation on growth of Scots pine was assessed with the use of the two meteorological parameters mentioned above. These parameters were used as their accumulated sums, calculated as of the dates of biometric measurements, made at the end of each month (the last ten days of a month) in the summer half-year period. Multiple regression analysis was applied to evaluate the effect of thermal conditions and precipitation on the growth of Scots pine in both variants and the significance of the relationships under study was examined with the use of an adjusted coefficient of determination R2. The analyses and calculations indicate a close significant relationship between the height of pine trees and their diameter at the base on any measurement date. Analyses of different measurement periods indicated a decrease in significance of the relationships between the height of pine trees and their diameter at the base. A decrease in these relationships is becoming more and more pronounced with the age of the trees. Of the two weather parameters, i.e. total air temperature and total precipitation, the precipitation dominates in the relationship with the trees height and air temperature – with the trees diameter.

Opis:: This paper aims to analyze the variability of the surface and ground water levels in Ambona peatlands. The depth at which the ground water table occurred was studied with reference to the adopted land drainage standards. The studies were carried out in 2009/10–2015/16 for natural and regulated water outflows. The analysis of annual total precipitation suggests that in the analyzed period some years were very wet (2009/10 and 2013/14), some were wet (2010/11, 2012/13 and 2015/16), one year was dry (2014/15) and one year was normal (2011/12). The 7-year average seasonal precipitation amounted to 598 mm, which was 71 mm higher than the average precipitation recorded in 30 years. The level of water in the river under adjustable outflow conditions ranged from 55 to 77 cm. The level of water under natural outflow ranged from 18 to 49 cm. In the area with adjustable outflow, the average draining depth was 47 cm. In the remaining area, not covered by the irrigation system, the draining depth was 64 cm. Additionally, the dynamics of variance in the water level under natural outflow conditions was clearly higher.

Opis:: The basis of this elaboration constituted data concerning mean starch content in nine medium-early cultivars of potato grown in six experimental stations belonging to CO-BORU (Research Centre for Cultivar Testing) in years 2010–2013. Using stepwise regression analysis the influence of thermal and precipitation conditions on starch content in potato cultivars was examined. Such analysis was performed for locations, years and particular cultivars. The analysis showed that starch content in tubers of medium-early potato cultivars depends more on precipitation than on thermal condi-tions. The relationship between starch content in tubers and precipitation and thermal conditions varied in different stations. In four stations (Karżniczka, Sulejów, Uhnin, Węgrzce) it depended on precipitation noted in August, in two (Uhnin and Słupia) – in July and in other two (Naroczyce and Słupia) – in June. Positive influence of temperature on starch content was noted only in August in Karżniczka. Starch content in tubers of Ametyst and Gawin cultivars depended on precipitation sum in August, Satina cultivar – in July, Oberon cultivar – in June and July, and Cekin, Finezja, Jurek, Stasia and Tajfun cultivars – on precipitation in July and August.

Opis:: Global climate change has led to significant shifts in local climatic conditions of Ukraine with the trend to aridity aggravation. Sustainable crop production is at risk due to the aridity level increase. The study is aimed to evaluate aridity index in Ukraine (on the whole country and individual regions’ scales) and the needs in irrigation using hydro-meteorological data of the key regional stations for the periods of 1961-1990 and 2010-2020. The results of hydro-meteorological evaluation were supported by the data on the soil moisture regimes provided by Soil Explorer service. The general trend to aridity aggravation in Ukraine was proved. It was found out that modern climate in most territory of Ukraine is semi-arid, dry subhumid and humid zones are observed in the western regions only. Humid soil moisture regimes (ustic and udic) are observed in the West and the North of the country. As a result of combined analysis of both aridity index and soil moisture regimes the conclusion was drawn that 46.05% of Ukrainian croplands cannot provide sustainable crop production without irrigation, 42.65% need irrigation for the cultivation of crops with high water use, and just 11.30% of the arable land require little or no irrigation.

Opis:: The paper presents an assessment of atmospheric drought during vegetation season defined on the basis of standardized precipitation index (SPI). The data used in this paper come from nine IMWM stations from central-eastern region of Poland, and they were registered in 1971–2005. The frequency of occurrence of vegetation season’s months was determined in particular drought classes. Spatial distribution of SPI index values was shown in all of the vegetation season’s months on the area examined. The direction and significance of values changes tendency of the analyzed index during the vegetation season were also defined. It was noticed that extreme droughts appeared four times less frequently than the normal months. Very dry months were noted most frequently in September while moderately dry – in August. The analysis of the frequency of spatial distribution of particular drought classes showed that extreme dry and very dry months occurred most frequently in western part of the area examined, while the moderately dry months also in south-eastern part. On the basis of the linear trend analysis it can be said that the SPI index values were slightly decreasing year by year.

Opis:: An urban wastewater treatment system was developed in Portugal for posterior in situ feasibility testing at the Bulgarian Antarctic Base, using its domestic wastewater. The aim of this system was to develop a low cost, integrated approach for wastewater treatment and production of nutrient solutions (NS) for hydroponic cultivation of lettuce (Lactuca sativa var. crispa) in Antarctic stations, or any other place where the lack of resources and logistical hardships make the wastewater treatment and reuse impractical. The wastewater treatment system consisted in manual agitation lime chemical precipitation (LCPm) and effluent natural neutralization (NN) by atmospheric CO₂ carbonation reactions (with and without air injection). The resulting effluent/NS had macronutrient values (nitrogen and phosphorous) for the hydroponic cultivation of lettuce below the values of commercial NS and a high pH (pH ≈ 8). The treatment achieved a total coliform removal rate of 100%. Before the LCPm treatment system development, several lime-based reagents were tested under different reaction pH and using mechanical agitation, to access their organic matter removal efficiency, as chemical oxygen demand (COD). The best COD removal results obtained were: commercial Ca(OH)₂ (pH 11.5 – 89%), reagent grade Ca(OH)₂ (pH 11.5 – 79%) and CaO (pH 12.0 – 64%).
