Long-Term Variations of Meteorological Parameters According to the Data of High-Altitude Weather Stations of the Central Caucasus

Abstract

The analysis of changes in meteorological parameters according to the data of two high-altitude weather stations of the Central Caucasus “Klukhorsky Pass” 1960–2020 and “Shatdzhatmaz” 1950–2020 was carried out. The weather stations are located at an altitude of about 2000 m. It has been established that in recent decades, the thermal regime of the high-altitude zone of the Central Caucasus is characterized by an increase in air temperature, which is most noticeable in recent decades and is 1.4° at the Klukhorsky Pass weather station and 2.2° at the Shatdzhatmaz weather station. Humidity data from the Klukhorsky Pass weather station show a long-term variation lasting about 35 years with highs near 1985 and 2010. Perhaps this is due to the Brückner cycle.
