SOLAR SIGNATURES WITHIN ATMOSPHERIC AND IONOSPHERIC PARAMETERS
Original language description
We have analyzed time series of solar data together with the atmospheric and ionosphericnmeasurements for last four solar cycles according to their availability. Within data of 1-daynsampling rate, we have searched for common spectral domains. As a convenient mathematicalntool we used Continuous Wavelet Transform (CWT) that is favorable for detection of wave-likenoscillations with limited duration and variable period. Then we looked for common oscillationndomains in the datasets using Wavelet Transform Coherence (WTC), which is a measure of thenintensity of the covariance of the two series in time-period space with stable phase difference.nDespite wide oscillation ranges detected by mean of CWT we found only limited domains bynmean of WTC, particularly significant high power domains (with stable phase difference) fornperiods 1 month, 2 months, 6 months, 1 year and 2 years between pairs of solar data, andnatmospheric or ionospheric data. The detected domains vary during particular solar cycle andnfrom cycle to the following one. These results indicate the changing solar forcing of thenatmosphere and/or its sensitivity with time.
