Trendy slunečního svitu na meteorologických stanicích s dlouhou dobou měření
Opatrná, Petra ; Sládek, Ivan (vedoucí práce) ; Hostýnek, Jiří (oponent)
One of the main objectives of this thesis is to identify the trends of sunshine which was measured on the meteorological stations and to explain it by the help of synoptical situations. Further, I would like to define the period, in which the days without sunshine dominate and the period, when the total of sunshine is higher, and to determine their influence on human's organism by means of the T and H index. I used data from eight meteorological stations, which are equable dislocated all around Czech Republic and are situated in the different elevations above sea level. Two of these meteorological stations (Praha - Karlov and Milešovka) have series of measurements which are in time longer than eighty years. In the first part of this thesis, I describe the measurement of sunshine and the factors, which affect it. Then I focus on the year totals of sunshine and I uncover their trends. The final chapters deal with the periods without sunshine which are called the dark periods and with the periods with higher total of sunshine which are called the periods of sunshine plentitude and their peripheries. The amount of sunshine had been going up until the fifties of the last century, after that came a distinct fall to the eighties when the trend was changing again and was raising up slowly. This fact harmonizes with...
