Using WRF mesoscale model to restore temperature profile in atmosphere boundary layer in Tomsk

In the paper, the possible use of a WRF mesoscale model for the detailed restoring of a temperature profile in the atmosphere boundary layer (ABL) during winter anticyclone is studied. The correctness of air temperature modeling as well as the possible use of a WRF model for predicting a vertical temperature distribution was show

Meteorological optical range predictability with the use of high resolution mesoscale models

The report describes and argues in favor of the data base for numerical experiments with hydrodynamic and photochemical atmospheric models with the purpose of the meteorological visibility forecast. The obtained results demonstrate methodological potential of this approach. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

Forecast of extreme weather conditions that promote aircraft icing during take-off or landing

This work presents the results of forecasting meteorological conditions that promote aircrafts icing in the atmospheric boundary layer; the forecasting results were obtained based on mesoscale meteorological model TSU-NM3. Godske formula which is based on the calculation of saturation temperature above ice, NCEP method, and statistical method of Hydrometeorological Centre of Russia were used as criteria of probability of aircraft icing during take-off or landing. Numeric forecast results were compared with physical observations made in the atmospheric boundary layer in October 2012 at the Tomsk airport. A good agreement obtained provided an opportunity to be certain about the above approach viability. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

Analysis of observations and results of numerical modeling of meteorological parameters and atmospheric air pollution under weak wind conditions in the city of Tomsk

The results of calculation of meteorological parameters using a meteorological model, TSU-NM3, as well as prediction of some indices of atmospheric air pollution in the city of Tomsk obtained from a mesoscale photochemical model are presented. The calculation results are compared with observational data on the atmosphere and pollutants

Pilot studies of the unique highland palsa mire in Western Sayan (Tuva Republic, Russian Federation)

In contrast to the well-studied West Siberian sector of frozen bogs in the Russian Arctic, the frozen mound bogs (so-called “palsas”) on the highlands of Southern Siberia have not yet been studied, but they are suspected to be even more sensitive to ongoing climate change. This article provides the pilot study on palsa mire Kara-Sug in the highland areas of Western Sayan mountain system, Tuva Republic. The study focuses on the current state of palsa mire and surrounding landscapes, providing wide range of ecological characteristics while describing ongoing transformations of natural landscapes under a changing climate. The study used a variety of field and laboratory methods: the integrated landscape-ecological approach, the study of peat deposits, geobotanical analysis, and modern analysis of the chemical composition of water, peat, and soils. The study shows that highland palsa mires are distinguished by their compactness and high variety of cryogenic landforms leading to high floristic and ecosystem diversity compared with lowland palsa mires. This information brings new insights and contributes to a better understanding of extrazonal highland palsa mires, which remain a “white spot” in the global environmental sciences
