The digital spectral analysis was carried out for centennial datasets of mean daily values of the surface air temperature anomalies at De Bilt and Lugano weather stations. In the power spectra of datasets peaks are found, which are associated with the influence of various terrestrial and space factors: the quasi-biennial oscillation, the pole tide, luni-solar tides, the rotation of the Earth – Moon system around the barycenter, and the solar activity.

The digital spectral analysis was carried out for centennial dataset of mean daily values of the surface air temperature anomalies at Basel weather station. In the power spectra of dataset peaks are found, which are associated with the influence of various terrestrial and space factors: the quasibiennialoscillation, the pole tide, luni-solar tides, the rotation of the Earth – Moon system around the barycenter, and the solar activity.

We carried out the analysis of the power spectrum of the time series of the daily values of the atmospheric pressure measured in high-level Alpine station Jungfraujoch in the time interval from 1968 through 1992.
