Abstract. We present the elements of a new advanced non-stationary theory of global mechanisms in atmospheric low-frequency processes, teleconnection effects to modelling global atmospheric behaviour, dispersion of radionuclides, assessing radioactivity impact of the Fukushima (Chernobyl) nuclear accidents on the environment. The approach is based on the energy, moment balance relationships for the global atmospheric low-frequency processes, atmospheric macroturbulence theory, link of tropospheric waveguides with atmospheric moisture circulation and, accordingly, with the shape of the atmospheric circulation over the position of the front sections of (atmospheric fronts as the main drives moisture). Atmospheric moisture cycle is linked with such typical low-frequency process as the angular momentum balance; the latter accounts violation of the atmosphere rotating balance with the Earth, which may be under developing meridional processes with the implementation of the mass transfer of air and steam between the tropical latitudes (with a large linear velocity) and slowly rotating А.

The approach is realized and implemented into the new microsystem technology "GeoMath-RadEnv" and focused on the testing and prediction of the air mass (particles) flows in the global atmospheric picture, determination of the new predictors for long-term and very long-forecasts of low-frequency atmospheric processes. PC experiments demonstrated the effectiveness of the approach in applying to modeling the balance of angular momentum, the transfer of atmospheric masses (moisture flow) with respect to the genesis of tropospheric waveguides, the continuity of atmospheric circulation forms (telecommunication, frontgenesis). The application of the method to the modeling of global atmospheric behavior, the scattering of radionuclides after accidents at the nuclear power plant in Fukushima (Chernobyl) demonstrates its effectiveness, which is confirmed by the physically reasonable agreement between the predicted and measured spatial distribution of radionuclides in the atmosphere, the direction and dynamics of the flows of air masses (particles).Keywords: atmospheric low-frequency processes, energy and angular momentum balance, teleconnection, global atmospheric behaviour and dispersion of radionuclides, nuclear power plant accidents and radiation-environmental consequences НОВИЙ БАЛАНСОВИЙ ПІДХІД ДО МОДЕЛЮВАННЯ МАКРОТУРБУЛЕНТНОЇ АТМОСФЕРНОЇ ДИНАМІКИ, ПРОСТОРОВОГО РОЗПОДІЛУ РАДІОНУКЛІДІВ В ГЛОБАЛЬНІЙ АТМОСФЕРІ, ЇХ ВПЛИВУ НА НАВКОЛИШНЄ СЕРЕДОВИЩЕ ПІСЛЯ ЯДЕРНОЇ АВАРІЇ НА АЕС ФУКУСІМААнотація.

Understanding sedimentation patterns in small coastal watersheds due to landscape perturbations is critical for connecting hillslope and fluvial processes, in addition to managing aquatic habitats for anadromous fish and other aquatic species in the Oregon Coast Range (OCR). Changes in sedimentation patterns spanning the last 250 years are preserved in two landslide‐dammed lakes in small watersheds (< 10 km2) underlain by the Tyee Formation in the central OCR. Dendrochronology of drowned Douglas‐fir stumps in both lakes provided precise timing of the damming and formation of the lakes, with Klickitat Lake forming in winter ad 1751/52 and Wasson Lake in winter ad 1819/20. Perturbations from wildfires, logging and road development, and previously underappreciated snow events affect sedimentation rates in the lakes to different degrees, and are identified in the sediment record using cesium‐137 (137Cs), high‐resolution charcoal stratigraphy, local fire records, and aerial photography. Each lake has variable sedimentation accumulation rates (0.05–4.4 cm yr−1) and mass accumulation rates (0.02–1.42 g cm−2 yr−1). Sedimentation rates remained low from the landslide‐damming events until the mid‐19th century, when they increased following stand‐replacing wildfires. Aside from a sediment remobilization triggered by human modification of the landslide dam at Klickitat Lake around 1960, the largest peaks in mass accumulation rates in the mid‐20th century at both lakes in the early 1950s precede major road construction and logging activity in the watersheds. Subsequent sedimentation rates are lower, but variable, and possible effects of logging and road development might be exacerbated by abnormal precipitation and heavy snow events. A comparison of previous studies of landslide‐dammed lakes in larger watershed of the OCR are consistent with our findings of increased sedimentation in the mid‐20th century, as well as higher sedimentation rates in the debris‐flow dominated southern Tyee Formation than in the lower‐relief northern Tyee Formation.

Definitions and dimensions of energy security: a literature review

This paper sheds light on an integral aspect of the global energy system: energy security. Energy security is a universal topic that shapes policies and regulations in order to achieve higher levels of energy security and thus provides societies with a better life. Understanding the concept and its implications requires a holistic definition, but current research literature lacks a commonly accepted, precisely defined definition. Therefore, the research gap is the absence of a comprehensive definition that takes into account all energy security dimensions, and the absence of well-studied relationships between energy security and its dimensions. Taking that in mind, the gap is addressed by a systematic review of energy security definitions and by building a structural dimensionalization of energy security. Thus, this review aims to track changing definitions of energy security in modern times and formulate a concise and comprehensive definition. Furthermore, using a structural approach, 15 dimensions, and related parameters of energy security are determined and categorized to illustrate the range of issues covered by the term and to enable precise evaluation of the energy security of energy systems. The results of this review show clearly how energy security could be defined generically to account all dimensions, and show the relationships between these 15 dimensions and energy security. Understanding all dimensions of energy security provides insights for policymakers to formulate policies that account for all of these dimensions.
