Климат определенной местности нельзя рассматривать изолированно. Особенности климата отдельных регионов это преломление общих закономерностей в конкретной обстановке. Так, погодные условия высокогорных об ластей Кавказа зависят от высотной поясности, циркуляции атмосферы, географического положения, особенностей растительного покрова и других факторов. Результатами данного исследования являются обработка пятилетних дан ных (с 2011 2015 гг.) по температуре воздуха приземного слоя атмосферы и их сравнительный анализ. Данные получены с помощью автоматической метеостанции, расположенной на высоте 1700 м н. у. м. в Безенгийском ущелье. В ходе ис следований было выявлено, что среднегодовая температура приземного слоя атмосферы за 2014 г. была выше таковой в другие годы в 1,5 2,2 раза. The Climate of an area cannot be considered isolated. The climate of certain regions is the refraction of the General laws in a speci c situation. So weather conditions in high mountainous regions of the Caucasus depend on altitudinal zonation circulation of the atmosphere, geographical position, peculiarities of the vegetation cover and other factors. The results of this study are veyears treatment data on the air temperature in the atmospheric surface layer and their comparative analysis. These results obtained at the meteorological station located in Bezengi valley, Kabardino Balkar highmountain reserve.

Temperature And Precipitation

Abstract 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.

Heating Test

Turnouts are key parts of rail roads and are exposed to adverse weather conditions such as snowfall, snow drifts, low temperatures, or sleet. Effective protection assures good turnout function and contributes to rail traffic efficiency and safety. Presently, resistance heating (RH) is the most common system of turnout heating in Europe. In this study, we attempted to implement energy-saving induction heating (IH) in order to cut costs of operation and electricity. A turnout heating test stand, including a stock-rail and a switch-rail, was executed in a climatic chamber. Air temperature was constant at the time of heating. Active power received by both the systems was identical for any measurement (450 W). Test results enabled an assessment of switch-rail position and variations of climatic chamber air temperature on growth of turnout temperatures. Effects of heating type on correct lubrication of the slide plate surface were compared. Dynamics of heating variations and their impact on effectiveness of snow or ice removal were defined for both heating systems. Turnout’s readiness for switch-rail shifting and lubrication conditions of turnout’s moving parts were compared. An in-depth comparative analysis of efficiency of RH and IH turnout heating was undertaken in the conclusion.

The paper contains the comparative analysis results of the rows of hydro/meteorological observations over 2017 in the Mayma River basin according to the Rosgidromet data (a hydro/post in the village of Mayma and a meteorological station in the village of Kyzyl-Ozek) and an autonomous gauging system (AK «Mayma») developed in Russian Academy of Sciences Siberian Branch Institute for Climatic and Ecological Systems Monitoring. We have found that in spite of the distance between the observation points («Mayma» is 4 km from the Kyzyl-Ozek meteorological station and 22 km from the Mayma village hydro/post) dynamics of changes of the Mayma River water level, air temperature and precipitation amount according to Rosgidromet data and the AK «Mayma» data agrees. We established a close correlation between rows of daily observations of the water level and air temperature (correlation indices 0.996 and 0.929, respectively). Correlation between observation rows of daily precipitation amount is weaker (correlation index 0.713), this is caused by spatial variations of precipitation distribution. Based on the conducted investigation results, we have made a conclusion about representativeness of the AK «Mayma» observation data. Reliability of observations, autonomous character of operations and possibility to transmit the observation operative data over some distance make «Mayma» gauging system a suitable instrument for the Mayma River basin hydro/meteorological status monitoring. It is possible to use the obtained hydro/meteorological information to forecast the river level regime and to provide operative data for executive bodies, units of Ministry of Emergencies and the population.
