The presented project was completed using modern, widely used IoT based devices. These include the ESP-01 microcontroller, which is programmable using the Arduino IDE (with its integrated ESP8266 interpreter), and a Raspberry Pi Zero W single board computer, which requires a Raspbian Linux distribution. In this project, an original meteorological station was created (complete with data acquisition), employing various sensors.
This paper presents the structure of weather types at four Siberian synoptic stations: Ostrov Kotelnyj, Verkhoyansk, Oymyakon and Yakutsk. The analysis has been performed on the basis of data published in the Internet database of synoptic messages OGIMET for the period of December 1999 to November 2013. Types of weather were determined based on the modified classification of weather types by Ferdynus (1997, 2004, 2013). The occurrence of particular groups, classes, and types of weather, and sequences of days with predominant weather types was identified. During the research period the structure of the weather types at the selected stations is characterized by a large number of observed types of weather, with the majority of them occurring with a low frequency. Frosty weather was predominant. The most frequently reported was the weather marked with numerical code 1100 (extremely frosty, clear without precipitation and calm) in Verkhoyansk (12.5%), 1300 (extremely frosty, cloudy without precipitation and calm) in Yakutsk (12.2%), 1200 (extremely frosty, partly clouded without precipitation and calm) in Oymyakon (11.6%) and 2201 (exceptionally frosty, partly clouded without precipitation and light breeze) in Ostrov Kotelnyj (6.7%).
2011 ). The aim of the study is to examine the variability of selected weather phenomena that are hazardous to aviation (thunderstorms, hail, fog and glaze) in central Poland, on the example of Bydgoszcz airport in the period 1971–2010. Methods and materials Bydgoszcz is a city in north-central Poland, on the Brda and Vistula rivers ( Fig. 1 ). The work uses 1971–2010 meteorological data from the Bydgoszcz-Airport meteorologicalstation. In the years 1951–82 the station operated under the auspices of the Institute of Meteorology and Water Management (IMGW) according
In order to assess the nature of climate change, it is important to analyze the indicators of climate variability in different scales: spatial and temporal. The analysis at different scales can lead to understanding of the nature of variations. Climate change studies are essential for comprehending the nature of global processes, to refine global climate patterns and also develop further research for natural processes (; ). Processes in nature are united, continuous and in constant interaction. Variance of interaction types are immeasurable, types can be connected with different scales and science fields, for example, biological, ecological, physical etc. If interaction is taking place between the land and atmosphere, it is defined as hydrological interaction. As water is significantly important for many purposes on the Earth, it is relevant to analyze precipitation and water runoff on a local scale. In the territory of Latvia, the amount of precipitation exceeds the level of evapotranspiration. Long-term monitoring data show that precipitation leads to average runoff of 250 mm per year (). The monitoring data collected at three research sites located in Latvia was used for this research including Berze (Lielupe river basin, meteorological station in Dobele), Mellupite (Venta river basin, meteorological station in Saldus monitoring) and Vienziemite (Gauja river basin, meteorological station in Zoseni). The results from this study show that there is a pronounced interaction between runoff and precipitation with an average of 53 to 82%.
In the paper, the results of field studies using automatic meteorological stations are presented. The studies were conducted in July 2005 – July 2006 in the vertical profile of Natural National Park of Carpathians. The results show that the thermal conditions in the area under research is strongly differentiated. Particularly large differences have been observed between the lowerings of the terrain (where the range of annual air temperature changes reaches almost 70°C, exceptionally high and exceptionally low temperature occurs often, and thermal inversions are frequently encountered) and the summit region (where the range of annual air temperature changes barely exceeds 50°C and the mean changes of daily air temperature are consideraly smaller).
This paper outlines the results of a study of Lviv’s specific thermal characteristics. The study relied on a series of measurements taken over a 15-month period (from February 2007, through April 2008) at 6 automatic meteorological stations, representing a variety of physiogeographic conditions and land use. The study reveals substantial variations of temperature levels (annual [1-3°C], seasonal [2-4°C], and daily [2-12°C] averages), indicating the presence of an urban heat island. The result of the study is a map of the distribution of average annual air temperatures on the territory of Lviv.
The following article presents the results of research on the influence of atmospheric circulation on air temperature and atmospheric precipitation in the Bydgoszcz-Toruń region (Poland) in the period 1921-2000. In order to do this, we have constructed a daily calendar of synoptic situations using criteria proposed by Niedźwiedź (1981). Daily values of air temperature and atmospheric precipitation were collected from the meteorological station in Toruń. Research results show that weather conditions in the study area are influenced predominantly by the direction of air mass advection and, to a lesser extent, by the prevailing type of isobaric system.
Assessing of IDF curves for hydrological design by simple scaling of 1-day precipitation totals
In this paper the scaling properties of short term extreme rainfall in Slovakia were investigated. The simple scaling theory was applied to the intensity-duration-frequency (IDF) characteristics of a short duration rainfall. This method allows for the estimation of the design values of rainfall of selected recurrence intervals and durations shorter than a day by using only the daily data. The scaling behavior of rainfall intensities was examined, and the possibility of using simple scaling in Slovakia was verified. The methodology for the simple scaling of rainfall is demonstrated using an example of the meteorological station in Ilava.
