A study on the influence of Dukovany power station on microclimate for the EIA documentation
Sokol, Zbyněk ; Řezáčová, Daniela
The study stems from the previous studies. We adapted the basic mathematical model CT-PLUME to assess the impact of cooling towers with natural draft, stationed in Dukovany site, on the given model area of 60 km x 60 km. The evaluation used meteorological data from 2010-2015 and compared the effect of the current towers with the new system EDU1-4 specified by the customer. This study differs significantly from the previous works in two aspects. It uses 6-year period (years 2010-2015) of data and analyzes the impact of 8 configurations with natural draft cooling towers contemplated in connection with the expansion of the Dukovany power station. The mathematical model CT-PLUME was adapted to the conditions of a specific task and is referred to as CT-PLUME / EDU_3.

Quantitative estimation of releases of airborne dust from the mine Bílina (Stage 2)
Sokol, Zbyněk ; Svoboda, Jaroslav
The aim of this study was to calculate the relative deposition of dust in the mine Bílina during the year 2012. The relative deposition was expressed in percentage of a total mass of dust that was created as a result of mining activities . These calculations were made for two sizes of dust (PM10 , PM2.5) and for different types of resources excavators, loaders, etc.). The annual average of the relative deposition was obtained by statistical processing of the calculated deposition for various meteorological scenarios. The scenarios were determined using the local meteorological measurements.

The impact of new water area on microclimate
Bartůňková, Kristýna ; Sokol, Zbyněk
In this contribution the impact of new water area on local climate is studied. The area of interest is newly originated lake Most in northern Bohemia. The impacts on microclimate that are evoked by physic-geographical changes in the area are studied by the help of the NWP model COSMO. The part of this model is Lake Model FLake. Input data are measured at the meteorological observatory Kopisty and at the lake station that measures also the water temperature in 16 vertical levels to the depth of 20 m. First results show significant influence of lake existence on air temperature, especially in summer months (June, July and August). The maximum influence is 1.2°C cooling in the surface level of the atmosphere. With the rising distance from the surface the impact on air temperature is decreasing.
