Description
  • Teplotní variabilita ČR je analyzována metodou vejvletů. Tato pokročilá časově-frekvenční analýza poskytuje informace o teplotních oscilacích. Zpracování je provedeno pro teplotní řady Prahy-Klementina, Brna, Milešovky a řadu ČR. Výsledky jsou prezentovány v podobě: a) trendů, b) periodičnosti a kolísání. Výsledky jsou prezentovány pro společné období 1930-2000 pomocí variančních spekter (významné cykly 8 a 12-14 let) a ukazují významný vzestupný trend ve všech případech. Vejvlet analýza byla provedena také pro kombinovanou teplotní řadu Severní polokoule podle Hadleyho centra. Diskutovány jsou některeé výsledky analýzy. (cs)
  • Temperature variability in the Czech Republic is analyzed by means of the wavelet transform. This advanced time-frequency analysis provides information about the nature and time-frequency localization of present oscillations. The data-set comprises four mean monthly temperature series from Prague-Klementinum, Brno, Mt. Milešovka and the gridded temperature series for the Czech Republic. The results of their wavelet transforms are presented as a) trend analysis (computed by the inverse wavelet transform) and b) periodicities and oscillations (distinguishable from the series wavelet power spectra and global wavelet spectra). The results show considerable similarity among individual series. Examples are the common time period between 1930 and 2002 expressed in all power spectra, the pronounced oscillations of about 8 and 12-14 years in all series, and the noticeable increase of temperatures in all cases. As a supplement to this study, wavelet transforms were performed on the variance-adjusted version of
