Opis:
The author discusses the impact of hydro-meteorological factors on the safety of fishing vessels through the presentation and discussion of the events that have taken place on the Polish fishing ships in the area of the Baltic Sea. Because it is not possible to compare the hydro-meteorological conditions on the ocean with the conditions of the closed sea, what is the Baltic Sea – the author has limited consideration to the South and the South-East Baltic which is the main area operation of Polish fisheries.It focuses mainly on criteria which have a direct impact on the safety of the fleet due to the size and nature of the work of fishermen.

Opis:
This study aims at studying the characteristics of some meteorological variables in Sokoto and its vicinity using probability distribution models. The thirty one (31) years data (i.e 1980-2010) were collected at Nigerian Meteorological Agency (Nimet) Oshodi and the data were subjected to various probability distribution analyses in order to resolute the best fit probability functions for each meteorological variables. The variables measured consist of Relative humidity, Rainfall, Temperature, Sunshine hours, Solar radiation, wind speed and Evaporation pitche. Whereas the probability distribution models adopt were Normal, Gumbel, Pearson type III and Log-Pearson type III distribution functions. Numerical equation were recognized and used to forecast the variables. Goodness of fit tests such as chi-square, correlation coefficient and coefficient of determination were carried out to obtain the reliability of the forecasted values. The model that satisfies the statistical tests conditions mostly was selected as the best fit model. The study revealed that Rainfall, wind speed, evaporation pitche are best fitted by Log-pearson type III probability distribution model, whereas the Relative humidity, solar radiation, sunshine hours and temperature the best model is Gumbel probability distribution.

Opis:
The aim of the present study was to analyse the Rumex pollen season dynamics in Lublin in 2001-2010 and to find relationships between season parameters and meteorological conditions. This study was carried out by the volumetric method using a Lanzoni VPPS 2000 trap. The start and end dates of each season were determined based on the 98% method. The effects of meteorological factors on the Rumex pollen seasons were analysed by employing Spearman’s correlation test. On average, the sorrel pollen season started on 13 May (±7 days), ended on 7 September (±6 days), and lasted nearly four months (±9 days). The highest pollen concentrations were recorded in June and July. A significantly negative correlation was found between season duration and Seasonal Pollen Index (SPI). During shorter pollen seasons, higher pollen counts were recorded. In all study years, the seasons were right-skewed. The pollen concentration was most strongly correlated with humidity and mean air temperature. The season parameters (onset, end, peak date, peak value, SPI value) were primarily dependent on air temperature before and during the pollen season.
Celem badań była analiza dynamiki sezonów pyłkowych Rumex w Lublinie w latach 2001-2010 oraz znalezienie zależności między parametrami sezonu a warunkami meteorologicznymi. Badania prowadzono metodą wolumetryczną przy użyciu aparatu Lanzoni VPPS 2000. Początek i koniec sezonu ustalono w oparciu o metodę 98%. Wpływ czynników meteorologicznych na sezony pyłkowe szczawiu analizowano stosując test korelacji Spearmana. Sezon pyłkowy szczawiu rozpoczynał się średnio 13.05 (±7 dni), kończył 7.09 (±6 dni) i trwał prawie cztery miesiące (±9 dni). Najwyższe stężenia pyłku notowano w czerwcu i lipcu. Stwierdzono negatywną istotną statystycznie korelację między długością sezonu a wartością SPI. W czasie krótszych sezonów pyłkowych notowano wyższe sumy ziaren pyłku. We wszystkich latach badań sezony były prawostronnie asymetryczne. Stężenie ziaren pyłku szczawiu w sezonie było najsilniej skorelowane z wilgotnością i średnią temperaturą powietrza. Cechy sezonu (początek, koniec, data wartości maksymalnej, wartość maksymalna, SPI) uzależnione były przede wszystkim od temperatury powietrza przed lub w czasie sezonu pyłkowego.

Opis:
The objective of the work was to determine the influence of selected meteorological elements on the concentration of PM10 and PM2.5 in the air as well as arsenic, cadmium, lead and benzoapirene contents in PM10. The work is based on the data collected by the automatic measurement station located on ul. Konarskiego, Siedlce, in 2013-2017. ANOVA demonstrated that the heavy metal content throughout the year was significantly influenced by the month of the year. The lowest concentration of arsenic was recorded from May to August, and cadmium from January to March as well as from October to December. Similarly to cadmium, the lead content was the highest in the winter months (from October to March). The analysis of correlation revealed that air pollution was predominantly affected by air temperature, wind speed and air humidity. The relationship between the air temperature and pollutant content was negative. As the temperature increased, arsenic, cadmium, lead, benzoapirene and the PM10 contents declined. It was found that an increase in wind speed contributed to a significant decline in the concentration of PM10 and PM2.5. Moreover, wind speed affected the heavy metal content. Relative air humidity influenced the metal concentration from November to May, whereas an increase in wind speed contributed to a significant decline in the concentration of only PM10 in the period from January to November.

Opis:
Meteorological hazard maps are one of the components of the IT System for Country Protection against extreme hazards (ISOK) created by a consortium of Polish institutions, including the Institute of Meteorology and Water Management – National Research Institute. These maps present meteorological phenomena such as: temperature extremes, heavy and flood-producing rainfall, strong winds, intensive snowfall, fogs, glaze, rime and thunderstorms with hail. These elements were chosen arbitrarily due to recorded or estimated losses. The main aim of the maps is to present visualization methods of hazard forecast with consideration of climatological (historical) background. To identify areas especially exposed to the above meteorological hazards, extensive climatological analyses were performed, based on long-term daily data (mainly the 1951-2010 period). The main component of the warning system is a set of prediction maps created automatically on the basis of scientific algorithms that provide the probability of the occurrence of particular phenomena, or the conditions favourable for them. The algorithms’ structure, based on information about physical processes in the atmosphere, as well as detailed climatological analysis, enables the reclassification of the forecast values – predicted by the ALADIN mesoscale atmospheric model – into four groups of any hazard at the gridded points. Finally, the information will be interpolated and will result in the production of maps of spatial distribution presenting the objective probability of a particular hazard, i.e. its actual risk. Results of historical analysis are to be presented for the public by a number of climatological maps, and accompanied by additional fact sheets to provide society with an actual view of the spatial distribution of the distinguished weather phenomena, and the interrelated risks.

Opis:
In the article, a brief review is presented of the definition of meteorological and agricultural droughts, drought indices and the operational systems of monitoring droughts in Poland. Drought is a widespread and frequent disaster which occurs more often within humid climate zones. Meteorological drought is the result of deficiencies in precipitation. Agricultural drought is an effect of various characteristics of meteorological and hydrological drought in agriculture comprising the reduction of evapotranspiration, soil water deficits, and reduced crop yield. Drought indicators are the common measures for drought assessment. The paper contains an inventory of drought measures (indicators) that are applied to evaluate meteorological and agricultural drought in Poland. For meteorological drought monitoring and the assessment of its intensity, four different indices have been used in Poland: relative precipitation index (RPI), effective drought index (EDI), standardised precipitation index (SPI) and climatic water balance (CWB). Agricultural drought is monitored by soil moisture index (SMI), agricultural drought index (CDI) and the potential reduction of final yield (yield reduction ratio YR). The working drought monitoring systems give information for the whole country or for a specific region but they are directed to some specific drought analyses. Four different drought monitoring systems have been under operation in Poland since 2005. The Institute of Meteorology and Water Management (IMGW) conducts the system called “POSUCH@”. The Institute of Soil Science and Plant Cultivation conducts the agricultural drought monitoring system. The Institute of Technology and Life Sciences (ITP) has developed two systems: the regional drought monitoring system in the Kujawy region and the nationwide system of monitoring and forecasting water deficit and surplus in agriculture.

Opis:
It is well known that the temporal dynamic of indoor and outdoor radon concentrations show complex patterns, which are partly not easy to interpret. Clearly, for physical reasons, they must be related to possibly variable conditions of radon generation, migration and atmospheric dispersion and accumulation. The aim of this study was to analyse long-time series of simultaneously measured indoor and outdoor radon concentrations, together with environmental quantities, which may act as control variables of Rn. The study was performed in Chiba, Japan, using two ionization chambers for parallel indoor and outdoor radon concentrations measurements over 4 years. Meteorological and seismic data were obtained from the Japan Metrological Agency (JMA).

Opis:
Road accidents are one of the basic road safety determinants. Most research covers large territorial areas. The results of such research do not take into account the differences between individual regions, which often leads to incorrect results and their interpretation. What makes it difficult to conduct analyses in a narrow territorial area is the small number of observations. The narrowing of the research area means that the number of accidents in time units is often very low. There are many zero observations in the data sets, which may affect the reliability of the research results. Such data are usually aggregated, which leads to information loss. The authors have therefore applied a model that addresses such problems. They proposed a method that does not require data aggregation and allows for the analysis of sets with an excess of zero observations. The presented model can be implemented in different territorial areas.
