Opis:
Characteristics of rainfall rate useful in the estimation of attenuation due to rain are presented. Rain data collected at Ogbomoso between January-October, 2009 were used in the analysis. Result shows that power law relationship exists between the equiprobable rain rates of two different integration times. The value of conversion factor CE and CR obtained for Ogbomoso are 0.28(60) and 0.64(90) respectively. Our result then shows that different conversion factor is required for different location even within the same climatic region.

Opis:
The study analyzes the temporal and spatial variability of atmospheric precipitation and the impact of global climate changes on precipitation in Wielkopolska. The study was based on data provided by the IMGW-PIB and collected from 5 synoptic stations located in central Poland. The average multiannual sums of precipitation, the average number of days with precipitation in total and the particular types of precipitation in 1981–2020 were calculated, and their spatial distribution presented. Moreover, seasonal precipitation totals and statistics for days with precipitation were also calculated, and trends of individual pluviometric characteristics presented. The average annual rainfall was 523 mm, and the average annual rainfall frequency was 163 days. Days with rainfall were more frequent than days with snow (35 days). Over the course of many years, there was an apparent decrease in days with snowfall (-6.5 per decade) and an increase in the number of rainy days (4.3 per decade). Annual precipitation totals show no significant long-term changes.

This paper presents data on daily precipitation totals from six meteorological stations and the climatic water balance for the stations located throughout Poland in 2011-2015. The following sequences of days without precipitation were distinguished: from 11 to 15 days, from 16 to 20 days, and of more than 20 days. The number of precipitation-free sequences during the growing season in 2011-2015 was highly variable. Over the studied period, there were from 1.0 rainless sequence in Wtelno to 2.4 such sequences in Gołębiów per one growing season. The most frequently occurring were sequences of 11-15 days, while those of 16-20 days were less frequent. In the years under analysis, all of the different sequences occurred most frequently in July, and the least frequently in April. The highest numbers of sequences without precipitation were recorded in the south-east of Poland (Zakalniki, Gołębiów).

For ungauged rivers, when there are no hydrological measurements and there is a lack of data on perennial flow rates, the latter one to be determined based on other hydrological data. The river Suhareka catchment represents a similar case. Since there is no data on Suhareka’s flow rates, the authors of this study aimed for the flow rate determination based on rainfall measurements. From the available data on annual precipitation (monthly sums) provided by the Kosovo Hydrometeorological Institute for the Suhareka hydrometric station, the observed monthly rainfall data for 30 years were analysed. Those gaps were initially filled by connecting the hydrometric station in Suhareka with those of Prishtina, Prizren and Ferizaj, and as a result a fairly good fit was ensured. Moreover, the intensity-duration-frequency curves were formed using the expression of Sokolovsky, as a mathematical model of the dependence I (T, P). For a transformation of rainfall into flow, the American method SCS was used. As a result, the equation for the Suhareka River basin was derived, which enabled the determination of maximum inflows, for different return periods. The results obtained through this paper, indicates that even for ungauged river basins the peak flows can be determined from available rainfall data.

Opis:
In this paper I propose to show: 1) that in Phys. II 8 Aristotle takes Empedocles as a paradigm for a theoretical position common to all philosophers who preceded him: the view that materialism implies a mechanistic explanation of natural becoming; and 2) that, since Empedocles is regarded as a philosopher who clearly expresses the position of all mechanistic materialists, Aristotle builds his teleological arguments precisely to refute him. Indeed, Aristotle believes that refuting the arguments of Empedocles – the champion of mechanism – means refuting the mechanistic theory itself. In order to illustrate this point, I will discuss some passages from Phys. II 8, while also turning to consider the Neoplatonic commentators on Aristotle’s Physics. I will then endeavour to explain why in 198b19 ff. Aristotle formulates the argument of rain, which has attracted so much attention from scholars of the Physics: I will consider whether Aristotle believes that rain serves a purpose, contrary to what he claims with regard to meteorological phenomena in Meteorologica.

Opis:
Przeprowadzone badania czasowo-przestrzennego zróżnicowania opadów we Wrocławiu na podstawie wieloletnich pomiarów wykazały, że obecna sieć pomiarowo-obserwacyjna nie sprosta zapotrzebowaniu na informacje, niezbędne do projektowania bądź modernizacji, w tym modelowania hydrodynamicznego, systemów odwodnieniowych. Dotyczy to zwłaszcza intensywnych opadów krótkotrwałych stwarzających duże zagrożenie funkcjonowania kanalizacji deszczowej i ogólnospławnej. W pracy wykazano znaczne różnice ilościowe wysokości i intensywności opadów w różnych rejonach Wrocławia. W szczególności w rejonie stacji meteorologicznej Wrocław-Strachowice (na zachodzie miasta) występują wyższe wartości natężeń opadów o ok. 20% w stosunku do rejonu stacji Wrocław-Swojec (na wschodzie). Wnioskowanie oparte na materiałach pochodzących z dwóch stacji może zatem powodować niedoszacowanie natężeń opadów w rejonach północnym i południowym miasta, na co wskazują wyższe wartości opadów dobowych na Psim Polu czy Oporowie. Należy zatem zwiększyć liczbę stacji automatycznie rejestrujących wysokość opadów w czasie, co w efekcie przyczyni się do lepszej ochrony całej aglomeracji wrocławskiej przed lokalnymi wylewami z kanalizacji czy podtopieniami.
Analysis of the space-time distribution of precipitation for the city of Wroclaw obtained from many years' measurements has demonstrated that the existing net-work of gauging stations fails to provide reliable data for the design or modernization, and primarily for the hydrodynamic modeling of draining systems. This finding holds true particularly for high-intensity rainfalls of a short duration, as they pose a real threat to the functioning of the storm water drain and combined sewage systems. The results of the study have revealed considerable differences in the amount and intensity of precipitation between particular parts of the city. Within the area of the Wroclaw-Strachowice station (in the western part of the city) the amount of precipitation received was by approx. 20% higher as compared to that within the Wroclaw-Swojec station (in the eastern part of the city). Drawing conclusions based on the data obtained from the two meteorological stations may lead to the underestimation of the precipitation amounts received in the northern and southern parts of the city, as can be inferred from the higher values of daily precipitation amounts measured in Wroclaw-Psie Pole and Wroclaw-Oporów. It is therefore recommendable to increase the number of stations that will provide automatic records of the precipitation amounts received with time. This will guarantee a more efficient protection of the municipality of Wroclaw against local flooding or outflow from the sewerage system.

Opis:
The research issue focuses on potential interception, which is the maximum amount of water that can be stored on plant surface. Tests under controlled conditions remain the best way to enhance knowledge on interception determinants in forest communities. Such tests can provide data for identification of mathematical models based on ecological criteria. The study presented in this paper concerned tree interception under simulated rain in a range from 2 to 11 mm/h. To perform the experiment a set of sprinklers was designed and built. The study included two deciduous species: beech (Fagus sylvatica L.) and oak (Quercus robur L.). Descriptive characteristic and nonlinear estimation were suggested for the obtained data. Interdependence of potential interception, the intensity of rain and the size of raindrops were described using exponential equation. The intensity and drop size of simulated rainfall significantly influence the obtained values of potential interception. Data analysis shows a decrease of interception value with an increase of intensity of simulated rainfall for both analysed species. Every run of the experiment that differed in the intensity and size of raindrops reached an individual level of potential interception and time needed to realize it. The formation of ability of plants to intercept water depends both on the dynamics and the time of spraying.

Opis:
Climate change causes various events, such as El Niño , and we experience their larger frequency. This study based on a quantitative approach uses observation data from the Umbu Mehang Kunda Meteorological Station and the Ocean Niño Index (ONI). As a result, East Sumba, which has an arid climate, has more challenges in dealing with drought and water deficits during El Niño. This study identifies rainfall when the El Niño phenomenon takes place in East Sumba through data contributing to the ONI value and dry day series from 1982 to 2019. The analysis was carried out by reviewing these data descriptively and supported by previous literature studies. The research found that there was a decrease in the accumulative total rainfall in El Niño years. The annual rainfall in the last six El Niño events is lower than the annual rainfall in the first six El Niño events. The dry day series is dominated by an extreme drought (>60 days) which generally occurs from July to October. This drought clearly has a major impact on livelihoods and causes difficulties in agriculture as well as access to freshwater. This results in crop failure, food shortages, and decreased income. The phenomenon triggers price inflation in the market and potential increase in poverty, hunger, and pushes the country further away from the first and second Sustainable Development Goals. This phenomenon and problems related to it need to be dealt with by multistakeholders.

Opis:
As population rises, more people need to be fed. With increasing income, the potential exists for increases in the demand for cereals (i.e., barley). Since barley has a high level of tolerance to environmental stressors, this crop has been recommended as a potential crop for food security in marginal environments. In this study, a crop growth Agricultural Land Management Alternatives with Numerical Assessment Criteria model, was parameterized and used to simulate the yields of two barley types grown in a temperate environment at a latitude of 35°N. In order to apply this crop model to barley, 19 years of field data were used to model calibration and validation. As a result, the ALMANAC model accurately simulated yields for both barley types. The validated model was used to predict yields under three diverse seasonal rainfall scenarios associated with different patterns of the Central Pacific El Niño influence. According to the simulation results, excessively high seasonal rainfall decreased barley yields. Crop price and annual revenue of the two barley types were also evaluated using a non-linear regression model. For the malt type, the food price was higher with a higher rainfall, while naked barley had a higher revenue under the conditions of a lower rainfall.

Climate, land use, and land cover change can propagate alteration to the watershed environment. The interaction between natural and human activities probably accelerates the change, a phenomenon that will generate serious environmental problems. This study aims to evaluate the change in the hydrological regime due to natural and human-induced processes. The study was conducted in Brantas watershed, Indonesia, which is the largest watershed in East Java. This area is populated by more than 8 million inhabitants and is the most urbanized area in the region. An analysis of rainfall time series use to shows the change in natural phenomena. Two land-use maps at different time intervals were used to compare the rapid development of urbanization, and the discharge from two outlets of the sub-watersheds was employed to assess hydrological changes. The indicator of hydrological alteration (IHA) method was used to perform the analysis. The daily discharge data are from 1996 to 2017. The research results show an increase in flow (monthly, 1-day, 3-day, 7-day, 30-day, and 90-day flows) in the two sub-watersheds (Ploso and Kertosono) from the pre-period (1996–2006) to the post-period (2007–2017).
