Astronomical Cycles in the Climatic and Geophysical Characteristics of Crimea

Climatic characteristics of the Crimean peninsula were analyzed on the basis of climatic parameters measured every day onboard NASA satellites for the period of 1983−2005. An accelerated increase in the insolation of Earth’s surface at the Kara-Dag site (as compared to that at other sites in Crimea) and an abnormal decrease in the surface temperature at the Fonar site have been revealed. The results of frequency−time wavelet analysis of local data on the insolation and temperature of the terrestrial surface enabled us to isolate periodic oscillations, the periods of which coincide with astronomical cycles, and determine an era of anomalous deviations from general trends of 1990−1995. From the analysis of corrections for vertical deformations of Earth’s surface at the Katsiveli site, a seasonal component was detected and parameters of this oscillation were calculated. Coherent variations with periods of approximately 10−12 and 60−70 years, which were found here, are inherent in the processes of different physical nature. They can be attributed to the global cycles in the Solar System, the manifestation of which in climatic and geophysical local processes is a result of the general trend towards synchronization. In this process, coherent variations of multiple or commensurate frequencies, may appear.
