measurements for solar cycles 19 till 23 according to particular data availability. For the analyses
we have used long term data with 1-day sampling. By mean of Continuous Wavelet Transform
(CWT) we have found common spectral domains within solar and atmospheric and ionospheric
time series. Further we have identified terms when particular pairs of signals show high
coherence applying Wavelet Transform Coherence (WTC). Despite wide oscillation ranges
detected in particular time series CWT spectra we found only limited domains with high
coherence by mean of WTC. Wavelet Transform Coherence reveals significant high power
domains with stable phase difference for periods 1 month, 2 months, 6 months, 1 year, 2 years
and 3 years between pairs of solar data and atmospheric and ionospheric data. The detected
domains vary significantly during particular solar cycle (SC) and from cycle to the following
one. It indicates the changing solar forcing and/or atmospheric sensitivity with time.Pracoviště Ústav fyziky atmosféry Kontakt Kateřina Adamovičová, adamovicova@ufa.cas.cz, Tel.: 272 016 012 ; Kateřina Potužníková, kaca@ufa.cas.cz, Tel.: 272 016 019 Rok sběru 2018
