Аннотация: The possibility is demonstrated of using intense interfering light fields to form a bulk, rectified, induced-light-pressure force, thereby making it possible to efficiently act on transport phenomena of a small resonant admixture in a buffer gas. This force is capable of inducing rotating or fixed spatially periodic structures in a dense gas. The symmetry and other characteristics of such a sharp periodic stratification of the gas are extremely sensitive to the spatial configuration, phases, and parameters of the fields acting on it.

Аннотация: In a brackish, temperate, 24-m-deep Lake Shira, the profiles of salinity, temperature, oxygen and sulfide concentrations were measured on a seasonal basis from 2002 to 2009. The lake was shown to be meromictic with autumnal overturn restricted to mixolimnion. The depth of mixolimnion and position of oxic-anoxic interface varied annually. The spring mixing processes contribute to the formation of mixolimnion in autumn. The exceptionally windy spring of 2007 caused the deepening of mixolimnion in the winter of 2008. The winter position of oxic-anoxic interface was affected by the position of lower boundary of mixolimnion in all winters. The salinity in the winter mixolimnion increased compared with the autumn because of freezing out of salts from the upper water layers meters during ice formation and their dissolution in water below. The profiles of salinity and temperature were simulated by the mathematical 1-D model of temperature and salinity conditions taking into account ice formation. The simulated profiles generally coincided with the measured ones. The coincidence implies that simplified one-dimensional model can be applied to roughly describe salinity and density profiles and mixing behavior of Lake Shira.

Аннотация: A one-dimensional numerical model and a two-dimensional numerical model of the hydrodynamic and thermal structure of Lake Shira during summer have been developed, with several original physical and numerical features. These models are well suited to simulate the formation and dynamics of vertical stratification and provide a basis for an ecological water-quality model of the lake. They allow for the quantification of the vertical mixing processes that govern not only the thermal structure but also the nutrient exchange, and more generally, the exchange of dissolved and particulate matter between different parts of the lake. The outcome of the calculations has been compared with the field data on vertical temperature and salinity distributions in Lake Shira. Lake Shira is meromictic and exhibits very stable annual stratification. The stratification is so stable because of the high salinity of the water. If the water in Lake Shira were fresh and other parameters (depth, volume, and meteorology) were the same, as now, the lake would be mixed in autumn. Using the newly developed models and using common meteorological parameters, we conclude that Lake Shira will remain stratified in autumn as long as the average salinity is higher than 3%.

Аннотация: In meromictic lakes such as Lake Shira, horizontal inhomogeneity is small in comparison with vertical gradients. To determine the vertical distribution of temperature, salinity, and density of water in a deep zone of a Lake Shira, or other saline lakes, a one-dimensional (in vertical direction) mathematical model is presented. A special feature of this model is that it takes into account the process of ice formation. The model of ice formation is based on the one-phase Stefan problem with the linear temperature distribution in the solid phase. A convective mixed layer is formed under an ice cover due to salt extraction in the ice formation process. To obtain analytical solutions for the vertical distribution of temperature, salinity, and density of water, we use a scheme of vertical structure in the form of several layers. In spring, the ice melts as top and bottom. These processes are taken into account in the model. The calculated profiles of salinity and temperature of Shira Lake are in good agreement with field measurement data for each season. Additionally, we focussed on the redox zone, which is the zone in which the aerobic layers of a water column meet the anaerobic ones. Hyperactivity of plankton communities is observed in this zone in lakes with hydrogen sulphide monimolimnion, and Lake Shira is among them. The location of the redox zone in the lake, which is estimated from field measurements, coincides with a sharp increase in density (the pycnocline) during autumn and winter. During spring and summer, the redox zone is deeper than the pycnocline. The location of pycnocline calculated with the hydro physical model is in good agreement with field measurement data.

Аннотация: Two mathematical models of admixture dispersion in a surface turbulent layer of the pool are considered. All hydrodynamic characteristics required for the models are determined using a thermodynamic model of the horizontally homogeneous upper turbulent layer of the ocean. Numerical experiments have been performed to estimate the influence of stratification on the admixture diffusion. The advantages and drawbacks of the models are discussed. The importance of consideration of the influence of stratification on admixture diffusion is shown.

Аннотация: The problem of linear baroclinic seiches in rectangular basin is considered. It is supposed that density is stratified into three layers. Internal waves are not taken into account. It is shown that one-dimensional model allows one to determine the positions of thermocline and halocline. The model also allows one to determine the values of temperature and salinity in the surface and bottom layers with satisfactory accuracy. Fluctuations of temperature and salinity in pycnocline are estimated by calculating parameters of baroclinic seiches. The results of calculations and measurements in Lake Shira are compared. © Siberian Federal University. All rights reserved.

Аннотация: Wind flows in meromictic saline lakes in which the water column is not mixed to the bottom for at least one year are studied. This leads to the formation of upper and depth layers with small density gradients, between which there is a water layer with a large density gradient. It has been shown that, depending on the density stratification and the wind speed, wind flows (in the vertical plane) of two types are possible: with one or two circulation zones. For a two-layer lake model, a criterion for the change in the wind flow regime is proposed.

Аннотация: Исследованы ветровые течения в соленых меромиктических озерах, в которых в течение как минимум одного года толща воды не перемешивается до дна. При этом формируются верхний и глубинный слои, в которых градиенты плотности малы, между ними располагается слой воды с большим градиентом плотности. Показано, что в зависимости от плотностной стратификации и скорости ветра возможны ветровые течения (в вертикальной плоскости) двух типов: с одной или двумя циркуляционными зонами. Для двухслойной модели озера предложен критерий смены режимов ветровых течений.

Аннотация: The in-situ data on the vertical structure and stability of the vertical stratification of saline Lake Shira over the past decade (2007–2015) are analyzed. Simplified mathematical models have shown that strong wind in the autumn of 2014 together with rather thick ice in the winter of 2015 caused a change in the circulation regime of this water reservoir from meromictic (incomplete mixing) to holomictic (compete mixing). Based on the results obtained, a circulation regime for deep saline lakes located in the continental climate zone, in particular, in the arid zones of Southern Siberia (Khakassia, Transbaikal, and Altai) can be predicted under various climate scenarios of the future. © 2017, Pleiades Publishing, Ltd.

Аннотация: Saline Lake Shira (Southern Siberia, Russia) was meromictic through the observation period 2002–2015. During the under-ice periods of 2015 and 2016, complete mixing of the water column was recorded for the first time, and hydrogen sulphide temporarily disappeared from the water column of the lake; i.e. in those years the lake turned to holomixis. In the summer of 2015, a sharp increase in chlorophyll a, organic carbon, zooplankton, and phytoflagellates was observed in the lake, which was probably due to the release of nutrients from the monimolimnion. Purple sulfur bacteria completely disappeared from the lake after the first mixing in 2015, and did not reappear despite the restoration of meromixis in 2017. Thus, it was demonstrated that purple sulfur bacteria are sensitive to the weakening of the stratification of Lake Shira. Based on the data of the seasonal monitoring of temperature and salinity profiles over the period 2002–2017, it was presumed that the main cause of deep mixing in 2015 was the weakening of the salinity gradient due to strong wind impact and early ice retreat in the spring of 2014. In addition, it was shown that in previous years a significant contribution to the maintenance of meromixis was made by an additional influx of fresh water, which caused a rise in the lake level in the period 2002–2007. Thus, we identified a relationship between the stratification regime of the lake and the change in its level, which provides valuable information both for the forecast of water quality and for reconstruction of the Holocene climate humidity in this region of Southern Siberia from the sediment cores of Lake Shira. © 2017 Elsevier GmbH

Аннотация: The development of modern technologies allows us to solve the problem of carrying out long-term measurements of velocity and temperature in lakes. The long-term local measurements of velocity have been conducted in Lake Shira (Khakassia) in the period 2014-2015.The velocity profile along the column of the liquid in Lake Shira occurs due to density summer stratification and wind. The horizontal velocities vary greatly in depth as well as in time. The principal component method has been performed to analyze the horizontal velocities. This method is widely used to evaluate complex space-time structures, since it allowsto describe the data compactly.The obtained data have been decomposed into empirically determined modes with different scales. This makes it possible to extract dominant modes in the data and in some cases to determine the corresponding physical process.The first empirical modes in all measures are analogous to the Ekman spiral of the stationary motion of a homogeneous liquid and the remaining modes can correspond to internal waves. © SGEM2017 All Rights Reserved.

Аннотация: Mathematical model was developed for simulation of Krasnoyarsk hydropower station (HPS) intake regime influence on ice and water temperature downstream of the dam. Current reservoir vertical temperature profile and water temperatures of downstream river were used for the verification of the model. Using this model we estimated influence of stratification, withdrawal position and discharge on temperature of water inflow into HPS. It was estimated that changeover to upper-layer intake from current deep-layers intake allows to increase water temperature of Yenisey at Krasnoyarsk city on 6-8 C at summer period

Аннотация: Mathematical models of hydrothermal processes for stratified flows in flow-through reservoirs are considered in the paper. Models are based on the equations of fluid mechanics and heat transfer. They are applied to describe the hydrothermal regime of the Krasnoyarsk Reservoir. It is assumed that the reservoir depth is varied continuously, and the reservoir width is varied in a stepwise way. A numerical algorithm to study two-dimensional vertically stratified flows in terms of the streamfunction and the vorticity is considered. Parametrization of coefficients of the vertical turbulent exchange is proposed. Numerical results for currents at the dam area of the Krasnoyarsk reservoir are presented. The numerical model allows one to determine the temperature of water entering the intake openings in relation to the stratification, the position of water intake and the flow rate of water.

Аннотация: Currents in lakes affect the distribution of hydrophysical and hydrobiological characteristics. Three-dimensional model study is an important step toward an improved understanding and reliable prediction of the distribution of hydrophysical fields. Salt stratified lake Shira refers to meromictic reservoirs. The depth of the upper mixed layer depends on many factors (even a few isolated, fairly rare facts of its complete mixing are known). The study of the influence of each of them separately is the task of mathematical modeling. The model results indicate that strong wind stress in the autumn can result in unstable density stratification, leading to intense vertical circulation. © 2019 IOP Publishing Ltd.
