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.
