Vliv chodu počasí na ekonomiku chovu skotu v podhorských oblastech
SVOBODA, Pavel
This thesis is focused on assessing the impact of weather changes on the performance and economics of grazing cattle in the border areas of south Bohemia. The aim of the study was to compare the progress of meteorological parameters observed in three years and put them into the context of the economy of livestock production. In the actual experimental part I focused on the search and processing of data for calculation of economic indicators and processing of meteorological data that provided me with the department of landscape management.
Solar-geomagnetic activity and weather changes. Observation results
Bochníček, Josef ; Hejda, Pavel ; Pýcha, Josef
The impact of solar and geomagnetic activity on pressure and temperature changes in the winter lower troposphere was investigated. It was found that although correlations between solar and geomagnetic activity in individual winter periods are weak, the pressure and temperature changes show similar magnitudes.
Solar-geomagnetic activity and weather changes. The mechanisms
Pýcha, Josef ; Bochníček, Josef ; Hejda, Pavel
The mechanisms in the paper described were based on the ideas enabling to explain the observed associations between the short-term changes in solar/geomagnetic activity and short-term changes in the lower atmosphere pressure and temperature fields. Special attention was devoted to the role of planetary waves, electrostatic fields and various phases of the QBO.
