Subject of research: air basin of Akhangaran valley affects adversely on the ecological zone due to a greater number of waste of the anthropogene origin.
Purpose of work: study of the synoptic and meteorological conditions of contaminants propagation in the Akhanagaran valley on the basis of hydrodynamic model of the transport taking into account topography of the valley; elaboration of recommendations to monitoring, diagnosis and short-term prognosis of contaminants propagation in the valley.
Methods of research: methods of scientific cognition including the methods of morphometric analysis, methods of climatic and statistical, cartographic and synoptic analysis, method of finite differences of solving hydrodynamic tasks.
The results obtained and their novelty: the technique which allows to use experimental data on wind regime in one of the valleys of Western Tian-Shan for other valleys with similar morphometric characteristics was defined; assessment of the state of air basin of the Akhangaran valley with various types of circulation during the worm and cold periods of the year was performed; the values of wind velocity which provide favorable and unfavorable conditions for purifying atmosphere against contaminants waste in the valley was found; link of favorable and unfavorable conditions purifying air with types of synoptic processes in Central Asia was established; the chart for monitoring, which includes short-term prognosis of the state of air basin was developed.
Practical value: methodic approaches, algorithm and recommendations of the thesis research can be used during drawing up the projects for positioning enterprises; during monitoring for the state of atmosphere in the ecologically tensed industrial areas of the valleys of Western Tian-Shan; when drawing up maps for evaluation of the state of contamination by industrial waste as well as during the teaching of the special courses: “Fundamentals of Ecology”, “Numerical methods of weather forecast”, “Physics of Atmosphere”, “Ecological Monitoring” etc.
Degree of embed and economic effectivity: the results obtained can be used in making managerial decisions on regulation of industries activity by Khakimiat of Akhangaran district of Tashkent region.
Field of application: elaboration of projects for positioning new enterprises, monitoring and prognosis for the state of air quality, teaching courses: “Fundamentals of Ecology”, “Numerical methods of weather forecast”, “Physics of Atmosphere”, “Ecological Monitoring”.
