Central Military Archives as information system
Pýcha, Josef ; Vlasák, Rudolf (advisor) ; Procházka, Milan (referee)
SUMMARY: The aim of the thesis is to define a development and contemporary status of the Central Military Archives as a information system. It describes the entire information cycle of a document from its origin through the deposition at the department of conservation, in the administrative and final archive at last. It shows Central Military Archives and its importance as a significant entity in the field of digitization. Finally the thesis analyses the issues of implementation of the system of electronic record services. [Author's abstract]

Analysis of the relation between geomagnetic activity and the phase of the North Atlantic Oscillation
Bochníček, Josef ; Hejda, Pavel ; Pýcha, Josef
The North Atlantic Oscillation is considered to be a very robust phenomenon. The analysis of tropospheric pressure and temperature deviations from their long-term averages realised on the data set of winter (January-March) periods 1963-2001, as well as wind deviations from their long-term averages pointed at close association between high geomagnetic activity and the positive NAO phase.
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.
Physical plausibility of "Sun-weather" research
Bochníček, Josef ; Hejda, Pavel ; Pýcha, Josef
The paper deals with the importance of three basic objections against the existence of causal link between the changes of atmospheric fields in the lower troposphere.
Association among the QBO, geomagnetic/solar activity and winter air pressure changes in the Northern Hemisphere
Bochníček, Josef ; Hejda, Pavel ; Pýcha, Josef
Analysis of the sea-level pressure changes in winter periods (January + February) 1952-1996 showed their close association with the QBO-phase and solar and geomagnetic activity level. The importance of individual activities for analyzed changes is evaluated and the mechanism that could explain the analyzed processes is described.
