THE INVESTIGATION ON TEMPERATURE REGIME IN THE HIGHLANDS OF THE KABARDINO-BALKARIEN AND KARACHAY-CHERKES REPUBLIC FROM 1951 tо 2015

E.A. Korchagina

The purpose is to investigate dynamics of climatic characteristics of air temperature in mountainous areas of Kabardino-Balkaria and Karachay-Cherkessia during instrumental measurements with data from the nearest meteorological stations. Research methods. Methods of mathematical statistics is the choice for data processing and calculation of climatic indicators and their dynamics. The periods of averaging for climate indicators correspond to the recommendations of the World Meteorological Organization. To eliminate the inhomogeneity of the initial data, we used the mean values of the air temperature in 24 hours for the temperature levels before 1966. The series have the same length by regression methods according to the nearest meteorological station. Research results. The research on correlation of mean month and season indicators of air temperature on meteorological stations Terskol (Kabardino-Balkaria) and Klukhorsky pereval (Karachay-Cherkessia) has shown high coherence of climate parameters in the region. The research of change in the annual course of air temperature in the region reveals that minimum shift since January for February in 1981–2000 in the highlands of Karachay-Cherkessia. Dynamics of average annual amplitude of air temperature shows statistically doubtful increase. In the explored region the maximum of 10-year mean values are at the beginning of the research period. The same is for 30-year means. The exception makes the summer parameter of 1981–2010 in Terskola which exceeds initial values on 0, 07 °C. At the beginning of the period (in 1951–1960), all seasonal anomalies of mean decade temperature, exceeds norm. The situation repeats only in 2006–2015 (except for winter anomaly in Terskol). Conclusion. Climatic characteristics and indicators of their dynamics in mountainous areas of the republics are close thanks to small distance between them and to location in the same altitude zone. It gives the grounds to consider the climatic regularities of activization of dangerous processes revealed in more studied areas of Kabardino-Balkaria for all considered territory. At all observed fluctuations of climatic indicators of air temperature in mountainous areas of Kabardino-Balkaria and Karachay-Cherkessia their change doesn't exceeds the standard deviation of levels during 1951–2015.
