Snow cover at the Čertova louka and the Modré sedlo sites (Krkonoše Mts) in winter 2010/2011
Tryzna, Vojtěch ; Engel, Zbyněk (advisor) ; Nyplová, Petra (referee)
Snow cover at the studied locations in the Eastern Giant Mountains in the winter of 2010/2011 were collected through periodic field measurements of snow cover height. For evaluation and interpretation of measurements was used data from the meteorological station on "Luční bouda" and published the results of previous measurements in the field. In the "Čertova louka" is located nivation hollow, which show an increase in the accumulation of snow, which melted in early June. In the "Modré sedlo" location, which is largely exposed to deflation, the snow lasted until the end of April. The distribution of snow cover at both sites in winter 2010/2011 were consistent with previous observations. Maximum height of snow cover was lowest (about 8.4 to 43.8 %) from the current observation and were recorded aproximately one month earlier (18. 2.). The main reason for the development of unusual snow was warm front with rainfall, which affected the studied area during March. Winter 2010/2011 has been in terms of power and duration of snow cover at the studied locations below average.

Variability in snow cover conditions at the Čertova louka and the Modré sedlo sites (Krkonoše Mts) during the period 2003-2013
Tryzna, Vojtěch ; Engel, Zbyněk (advisor) ; Jeníček, Michal (referee)
This work summarizes one decade of spatial snow cover distribution research on the highest plateau of Eastern Krkonoše. This research was done in respect to periglacial landforms, which develop on these localities. The research was carried out during winter seasons 2003/2004 until 2012/2013 on Čertova louka meadow and Modré sedlo saddle. The main goal of the study was to analyze spatial snow depth variability during the season. Next goal was to analyze of possible interaction of snow distribution between both localities.The measurement was carried out manually by snow probe within regular net of 141 points. Our data were further compared with snow depth on professional meteorological station near Luční bouda chalet and with regular measurements of mountain rescue guards. As the main indicator of spatial snow distribution during the season was calculated general variability index. The highest values of snow depth were regularly reached at central terrain depression at Čertova louka meadow (max. 570 cm). On the other hand the lowest values were reached on the edge of Modré sedlo saddle (min. 35 cm). The difference between those two localities is also documented by values of general variability index for Čertova louka meadow (97) and for Modré sedlo saddle (33). The greatest values were usually...
