Six up-to-date reconstructions of hemispheric and global temperatures and two indices of volcanic activity were analyzed using both Fourier and wavelet approaches over time intervals of up to 1500 years. A cyclicity with a period of 188–250 years w

Introduction. A rapid increase in the number of objects that simultaneously take part in combat operations in the air requires improvement of systems for recognizing military objects both in terms of qualitative and quantitative indicators. This requ

Reconstruction of the summer (December–February) temperature of the southern part of the South American continent was studied in the time interval 900–1995. Significant temporal variations with periods of ca 520 years, ca 220 years, and 90–150

Three multi-proxy reconstructions of temperature in the Southern Hemisphere, were analyzed over the last millennium. Fourier and wavelet analysis showed that century-scale (55–120 years) and bicentennial (ca 250 years) variability is present in thi

Nine proxies of temperature over the last 225–300 years in Southern Fennoscandia (55–63° N) were analyzed. Seven reconstructions of the mean growing season temperatures were obtained by dendroclimatological methods. Reconstructions of spring tem

Fifteen proxy records of summer temperature in Fennoscandia, Northern Europe and in Yamal and Taymir Peninsulas (Western Siberia) were analyzed for the AD 1700-2000period. Century-long (70-100year) and quasi bi-decadal periodicities were found from p

The data on the content of the 14C cosmogenic isotope in the natural archives make it possible to study the solar activity (SA) in the past centuries and millennia. However, the 14C content in the natural archives is influenced not only by the intens

Solar-climatic correlations were examined over the timescales, corresponding to solar cycles of Schwabe, Hale and Gleissberg, during the last 3–4 centuries using eight proxy and direct indices of: (a) summer climate in Fennoscandia, (b) sea surface
