Solar variability effects on characteristics of the Northern Hemisphere Circumpolar Vortex
Paličková, Lea ; Huth, Radan (advisor) ; Bochníček, Josef (referee)
This thesis contains an introduction to the problematics of solar activity variations in relation to tropospheric air circulation.It also contains thorough description of the influence of the solar activity on variable aspects of atmospheric circulation in the stratosphere and troposphere. The main target of this thesis is to determine, whether and how much is the Northern Hemisphere Circumpolar Vortex and its characteristics (surface, roundness, location of the centre) influenced by the level of solar activity. In the research part of this thesis, these characteristic values of the northern hemisphere circumpolar vortex from selected months in the years 1959-2001 are used. The thesis conributes to the international project COST ES1005 (Towards a more complete assessment of the impact of solar variability on the Earth's climate).

Analýza dlouhodobého vývoje jasu noční oblohy na Observatoři Pierre Augera
Podškubka, Radek ; Prouza, Michael (advisor) ; Trávníček, Petr (referee)
In this paper we compare night sky brightness at the Pierre Auger Observatory with the flux of the solar extreme UV radiation. The night sky brightness is measured for monitoring purposes during operation of fluorescence detectors. The data were processed several times under slightly different conditions that should exclude the impact of moonlight, artificial light pollution and cloudiness. If one does not consider the effects mentioned before, the main source of night sky brightness is an airglow. The goal is to show that night sky brightness correlates with the flux of solar extreme UV radiation, what will confirm that extreme UV radiation is the cause of the airglow origin.

Sun - exceptionally star
KARHAN, David
Aims of this bachelor work is create summary knowledge from areas of solar physicist. Works should catch history of research work naší nextdoor star, up to present day. Part of works atempt at understanding process at the core as well as in top particle solar atmospher, solar activity, rise and process Sun, upcountry structure, watcher organization in the Sun as well as watcher actions in connection with Sun and apparatuses for sightings Sun.
