Opis:
The aim of the study was to evaluate the effect of different cultivars and weather conditions on the content of minerals: K, Na, Mg, Ca, Zn, Cu, Mn and Fe in linseed (Linum usitatissimum L.). In total, 11 common flax cultivars of four utility types were analysed. Field experiments were carried out in Poznań (Poland) between 2003 and 2005 and between 2008 and 2014. The study showed that the chemical composition of flax seeds was determined by differences between cultivars, the weather conditions and the cultivar-year interactions. The seeds of the Alba cultivar, representing the fibre type, had the highest content of all the elements measured in our study. The results demonstrated that none of the four types of utility cultivars was distinguished by a particularly high content of minerals in the seeds. Hence, the seeds of the flax cultivars of all the types used in our study may be used as sources of valuable macro- and microelements. The content of some minerals in the seeds of different flax cultivars was significantly correlated with the average temperatures and the average rainfall during the research period. The concentrations of calcium and zinc were not correlated with the weather conditions. The content of four elements (Na, Mg, Cu, Fe) was negatively correlated with temperature, whereas the content of potassium was positively correlated with this factor. Concentrations of three elements (K, Na, Fe) were negatively correlated with rainfall, whereas the concentration of manganese was positively correlated with this factor.

In October 2014 in a building of Rzeszow University of Technology, a series of measurements was taken to calculate the parameters of a solar system with a flat collector, as installed on the roof of the building. The following parameters were obtained: the value of solar radiation intensity, the temperature of external air, the temperature on the collector, the temperature of water in the tank and the temperature of glycol on the supply and return lines. On the basis of the data received, charts were made to visually present how changes of solar radiation intensity affected parameters of the system. The study was conducted in autumn when the intensity of solar radiation decreases, compared with summer months. The publication aims to show that the solar system brings energy gains in periods of transition, and the instantaneous intensity of solar radiation are comparable to those in the summer.

Opis:
Arctic, especially western coast of Spitsbergen has been a field of taking research by scientist from UMCS and AR in Lublin for more than 15 years. Researches have been taken there are connected with earth sciences like: meteorology and climatology, geomorphology, hydrography, geology and agriculture and botany. Meteorological observations were steady point of researches taking on every UMCS?s trips in Spitsbergen. At the beginning, at the 1986-1988 seasons were very wide, and measurements were taken every 3 hours. Between 1989 and 1999 measurements were taken 4 times a day a.e. every 6 hours. Since 1999 measurements have been doing by automatic stations. Appliance this equipment let us taking measurements with 10 minutes time step. The aim of this paper is to present course of meteorological conditions during the scientific trip to Spitsbergen in 2001 at the background of period 1986-2000. There were made comparisons of course mean daily four meteorological elements as: air temperature measured at 200 cm height [°C], wind speed [m/s], cloudiness, and precipitation [mm] from 2001 season with data collected during 15-years UMCS geographical trips on Spitsbergen. We can make statement that in thermic season 2001 was a bit cooler (0.1°C) than the period 1986-2000. At that season variability of mean daily temperatures was lower than in period. The lowest mean daily temperature was 2.5°C, and all days in period 2001 were lukewarm. The rate of mean daily cloudiness in period 1986-2000 is compensated. 2001 season was the same as other seasons during period. The air masses are strongly modified by circulation and orography. Season of 2001 was featured by lower mean daily wind speed (3.2 m/s) than in the period ? 4 m/s, also highest mean daily wind speed in 2001 was lower than in period 1986-2000. The greatest variability of four analysed elements on that period has precipitation. The variable of this element exceed 71.7 mm, which we can express as a ratio 1 to 20. 2001 season was dryer than mean of period about 11 mm.

Opis:
In recent years, the world, including Europe, has seen a much higher incidence of extreme weather phenomena. The ongoing climatic changes have a direct impact on the condition of surface waters. Groundwater is less affected by anthropogenic pollution than surface water, since groundwater can be used in distribution systems for municipal purposes, for food purposes, sold in unit packages, and for medicinal purposes (in drinking and bathing treatments). In Poland, a country with poor water resources, the problem of water scarcity due to climate change may even increase. One solution to this problem may be the increased use of Polish groundwater resources. Hydrogeological conditions favorable to the construction of drill wells, detailed identification of available groundwater resources throughout the country and the low degree of their usage (25% on average) make it possible to increase the intake of groundwater to cover this water deficit, especially in periods of drought.

W opracowaniu scharakteryzowano przebieg warunków pogodowych podczas XXVI Wyprawy Polarnej Uniwersytetu Marii Curie-Skłodowskiej na Spitsbergen. Pomiary wykonywano od 8 lipca do 1 września 2014 roku za pomocą automatycznej stacji meteorologicznej zainstalowanej w Calypsobyen (Bellsund, Svalbard). Analizie poddano temperaturę i wilgotność względną powietrza na wysokości 200 cm nad powierzchnią gruntu (n.p.g.), temperaturę powietrza przy gruncie (5 cm n.p.g.) oraz prędkość i kierunek wiatru. Uzyskane wyniki zostały porównanie z danymi, dla okresu wspólnego, z dwudziestu sezonów pomiarowych z lat 1986-2011 tj. od 10 lipca do 25 sierpnia.
Arctic is an area which rapidly react on the changes in environment. The weather conditions react the most quickly and determine other changes in geosystem. That is why the meteorology is the subject not only for meteorologist and climatologist but also for other researchers (like geomorphologists, hydrologists) and makes the background for their research in polar region. The region of Wedel Jarlsberg Land (western coast of Spitsbergen) has been a field of taking research by scientist from the Maria Curie-Skłodowska University (Lublin) for almost 30 years. Meteorological observations were carried out since 1986. At the beginning, measurements were taken every 3 or 6 hours. Since 1999 measurements have been doing by automatic stations taking measurements with 10 minutes time step (144 times per day). The aim of this paper is to present course of meteorological conditions during the XXVI Expe-dition of UMCS to Spitsbergen in 2014 on the background of multiyear 1986-2011. The station was located on Calypsostranda, a flat sea terrace, at the height of about 23 m a. s. l., at a distance of 200 m from Bellsund Fjord and 2 km from the Scott Glacier. The substratum was made of dry lichen-moss tundra. In 2014, the meteorological investigation began on 8th July and ended on 1st September. The mean daily air temperature at the altitude of 200 cm amounted to 5.9°C throughout the measurement period. The highest mean daily temperature (8.4°C) was recorded twice: the 23rd July and 4th August. The lowest mean daily temperature (3.1°C) was recorded the 31st August. Mean daily air temperature at the altitude of 5 cm also amounted to 5.9°C. The highest temperatures are recorded around 12 UTC, and the lowest just before midnight. In the 5-18 UTC temperature at 5 cm is higher than the temperature at 200 cm. The highest maximum temperature at the altitude of 200 cm (12.2°C) and at the altitude of 5 cm (14.0°C) was recorded the 4th August. Minimum temperature at the altitude of 200 cm (1.5°C) was recorded the 27th August and at the altitude of 5 cm (-1.7°C) the 25th August. The mean daily relative humidity at a height of 200 cm above the ground amounted to 85% and only twice (4th and 24th August), the humidity dropped below 60%, which was associated with the presence of foehn from the East. For the whole measurement period, the total precipitation amounted to 38.6 mm. 17 days with a precipitation ≥ 0.1 mm were observed (which means that rainfall occurred in 30% of the days). The highest rainfall amounted to 9.6 mm and occurred on 10th July when the air temperature at the altitude of 200 cm decreased from 10.2 do 5.6°C and the weak south wind changed direction to the west, and his speed increased to more than 7 m∙sˉ¹. The mean wind speed was 3,6 m∙sˉ¹ throughout the season. To compare selected meteorological weather conditions of the summer season 2014 against the multiyear 1986-2011, based on data for the period that is common (10th July – 25th August). The mean daily air temperature in 2014 was up to 1.1°C higher than the average temperature of period 1986-2011. Only season of 2002 was characterized by higher average temperature (6.3°C). The sum of the 2014 season precipitation was lower than in multiyear. The mean daily wind speed of season 2014 was 3.6 m sˉ¹ and was lower only by 0.7 m ·sˉ¹ from the mean of multiyear. During the season 2014, the winds from W were dominated (25.7%), while its frequency in other seasons does not exceed 5-10%.

For the prisoners of the concentration camps winter with its seasonal attributes as the icy cold or snow is more than a meteorogical phenomenon. The arrival of winter not only announces the annihilation of the prisonners, but also and perhaps above all their dashing and the unspeakable suffering to come out. In this paper we wish to study in the light of such authors as Robert Antelme, Charlotte Delbo, Primo Levi, David Rousset and Jorge Semprún how the hard weather conditions are able to redraw the space and the prisoners’Horizon of despair.

Every year a very large number of people die on the roads. From year to year, the value decreases, there are still a very high number of them. The pandemic has reduced the number of road accidents, but the value is still very high. For this reason, it is necessary to know under which weather conditions the highest number of road accidents occur, and to know the forecast of accidents according to the prevailing weather conditions for the coming years, in order to be able to do everything possible to minimize the number of road accidents. The purpose of the article is to make a forecast of the number of road accidents in Poland depending on the prevailing weather conditions. The research was divided into two parts. The first was the analysis of annual data from the Police statistics on the number of road accidents in Poland in 2001-2021, and on this basis the forecast of the number of road accidents for 2022-2031 was determined. The second part of the research, dealt with monthly data from 2007-2021. Again, the analyzed forecast for the period January 2022-December 2023 was determined. The results of the study indicate that we can still expect a decline in the number of accidents in the coming years, which is particularly evident when analyzing annual data. It is worth noting that the prevailing pandemic distorts the results obtained. The research was conducted in MS Excel, using selected trend models.

In the world weather derivatives play an important role in securing companies from energy industry. That industry was a pioneer in the use of weather derivatives and their creation was a natural response to the demand for this type of protection against weather risk. The article aims are to answer the question whether the energy industry companies in Poland are also vulnerable to the negative impact of not catastrophic weather risk and how a hedge instrument, diminishing the effects of prevailing weather conditions and securing the revenues of the industry might look like-. Owing to the analysis of the obtained results, we can conclude that weather conditions have a significant impact on the revenues of power companies. It is therefore reasonable to consider the introduction of weather derivatives on the Polish market. This article presents theoretical constructs of weather derivatives on the stock market and outside it.

The article presents some aspects of planning and conducting reconnaissance in mountainous terrain. The mountainous terrain has played a significant role in numerous battles and has been the key area creating opportunities for further actions. Intelligence staff is responsible for gaining the information necessary for military decision making process. Intelligence cell conducts IPB process during mission planning and throughout the operation. By applying intelligence preparation of the battlefield, commanders gain the information necessary to selectively apply and maximize operational effectiveness at critical points in time and space. There are many considerations affecting organization of reconnaissance in the mountainous terrain. IPB identifies the facts and assumptions about the enemy, terrain, weather, and civil considerations that allow effective staff planning. A reasonable estimate of the terrain and the enemy may pose many difficulties. The main task of the reconnaissance units in such a terrain is to find out the presence, the organization and positions of the enemy troops. The proper organization of observation system in mountainous terrain is one of the most important planning issues for intelligence cell. Knowledge about the terrain is a key factor to defeat your opponent in the battle.

The aim of the study washas been to determine the differences in the 24-hour means values of some selected meteorological elements between the stations analysed and also to determine the influence of atmospheric circulation on their distribution. Meteorological data collected at the Polar Station of the Institute of Geophysics of the Polish Academy of Sciences in Hornsund and the Calypsobyen Station of the Maria Curie-Skłodowska University of Lublin wasere used for the present research. The present studies showed that air temperature in Calypsobyen is on average 0.6°C higher than in Hornsund. Calypsobyen is warmer than Hornsund fromat almost all circulation directions. Hornsund is warmer only in the case of the NW direction. The highest levels of temperature differences (> 1°C) occur from theat S and SW directions. Calypsobyen was 0.3°C colder than Hornsund only in the case of the NWc type. Regarding the average total cloud coveriness of the sky [0-10], the difference between the two stations analysed was as small as 0.1. This results from thea high total cloud coveriness of the sky during summer. No differences were found in the case of medium wind velocity levels similarly as was in the case for the of cloud coveriness. The a mean difference forro this parameter was 0.1 m/s. The location of the station, as well as the orographic reletions in its surroundings, exerts a significant influence on the difference in thetiation of wind velocities in relation to the directions of the circulation directions. The total - taken ever twenty-four hour sums - of the atmospheric precipitation levels as an averaged with to the circulation directions in Hornsund were on average 0.8 mm higher than for in Calypsobyen. Precipitation levels were higher in Calypsobyen only from theat N and E directions and in the situation of a weather wedge over Spitsbergen (Ka), however, even then the values of these differences were small (0.1-0.2 mm). Analysis of the data analysis pointed to the significance of the direction of the circulation direction and its influence on the value of differences between the meteorological elements selected. In some cases (i.e. wind velocity, precipitation level) local factors - and including orographic relations and the location of the measuring site - are decisive.

Zastosowanie programowania dynamicznego obiektywizuje wybór drogi statku uwzględniając dynamicznie zmieniające się warunki pogodowe, charakterystykę statku jako obiektu sterowania i założone kryteria optymalizacji. W obliczeniach mogą być zastosowane różne typy algorytmów z teorii grafów skierowanych, programy ewolucyjne oparte na algorytmach genetycznych oraz algorytmy stosowane w metodzie izochron. Na przykładzie wyników podróży statków rekomendowanych przez armatorski Ośrodek Polskiej Żeglugi Morskiej uzyskano 3% oszczędności czasu podróży oceanicznych w stosunku do tras sezonowych.
Increasing accuracy of weather forecasts for ocean areas (wave factors, limits of ice), development of communication means, receiving and computations of navigational and weather information (satellite communication, computer programming) as well as development of theoretical basics of optimization and decision making process permit operational computations of optimal routes for ships on the oceans. Using dynamical programming, route selection is made objectively, taking into account dynamical changing weather conditions, ship characteristics and assumed optimization criteria. For computations different types of algorithms may be used: from graph theory, evolutionary algorithms based on genetic algorithms as well as isochrone ones. Following an example of results of ships voyages recommended by Polish Steamship Company routing centre, 3% of time voyage saving in comparison with seasonal voyages were obtained.

Renewable energy resources have become a promissory alternative to overcome the problems related to atmospheric pollution and limited sources of fossil fuel energy. The technologies in the field of renewable energy are used also to improve the ventilation and cooling in buildings by using the solar chimney and heat exchanger. This study addresses the design, construction and testing of a cooling system by using the above two techniques. The aim was to study the effects of weather conditions on the efficiency of this system which was installed in Baghdad for April and May 2020. The common weather in these months is hot in Baghdad. The test room of the design which has a size of 1 m3 was situated to face the geographical south. The test room is thermally insulated and connected to a solar chimney which generates a convection current to draw the air out of the room through a heat exchanger. The heat exchanger was submerged in a water tank of 2 m length, 1 m width and 1 m height. It was also covered with a layer of soil mixture with a thickness of 10 cm. The experiment simulates the natural conditions of a shallow water surface, connected to the room from the other side. The study results revealed that the air temperature inside the test room was lower than that of the ambient air outside. Pearson correlation coefficient showed that there was a strong direct relationship between solar radiation, temperature and wind speed from one side and the cooling efficiency from the other side. Also, there was a negative correlation between relative humidity and cooling efficiency.

During the last several years, as a consequence of the greenhouse effect, an increasing number of storms was observed in Poland. Storms are often categorized as catastrophic. This article demonstrates the main factors leading to serious damage of trees. Breaking and falling down trees or branches causes significant property damages and may contribute to deaths. It would be possible to prevent some accidents if there were any diagnostic methods that could predict imminent fracture of trees. In many cases competent care is enough, especially in canopy pruning and planting planning. To reach this goal, it is necessary to raise public awareness in this field.

Opis:
Zbadano częstość występowania posuch i pogody wybitnie wilgotnej w maju lat 1971-2000 na podstawie notowań sum opadów i średniej temperatury powietrza w 16 stacjach meteorologicznych zlokalizowanych w różnych regionach klimatycznych kraju. Na podstawie zastosowanej klasyfikacji warunków pogodowych ustalono, że 30% wszystkich notowań świadczy o wystąpieniu posuch różnego rodzaju i o różnym nasileniu. Posuchy występowały w całym kraju, najczęściej w okolicach Zielonej Góry, Poznania, Wrocławia i Torunia. Niezależnie od regionu, pogodę w czasie posuch charakteryzowały podobne wartości badanych elementów meteorologicznych. Miesiące uznane za wybitnie wilgotne stanowiły ok. 6% zbioru przypadków. Pogoda wybitnie wilgotna w maju wystąpić może w różnych regionach Polski, lecz najczęściej zdarza się w regionie nadmorskim (Koszalin) i na południu kraju (Rzeszów, Katowice i Kraków).
Frequency of semi-droughts and extremely wet weather events were analysed based on rainfall and mean air temperature recorded in May from 1971 to 2000 in 16 meteorological stations. Weather classification used in the present study showed that 30 % of all records pointed to the occurrence of sem-drought of various kind and intensity observed mainly in Zielona Góra, Poznań, Wrocław and Toruń. Irrespective of the region, similar values of meteorological elements characterized the weather during semi-drought events. Extremely wet months constituted about 6 % of records. In May extremely wet weather was observed in different regions of the country, most frequently in seaside (Koszalin) and southern part of Poland (Rzeszów, Katowice and Kraków).
