Active development of mountain territories on the black sea slope of the Main Caucasian ridge requires high-quality engineering and hydrometeorological surveys. In the current Set of rules of SP 131.13330.2012 "Construction climatology", which is an updated version of SNiP 23-01-99, there is no climate microdistricting of the Greater Caucasus and territories associated with the settlement Krasnaya Polyana. This gap leads to serious errors in design and survey work associated with the use of incorrect values of meteorological characteristics. The range of heights covered by construction activities covers an area from 550 to 2200 m. In this range, the values of meteorological characteristics vary within very large limits. A method of climatic zoning of the territory of mountain areas is proposed on the example of the Fisht-Oshten mountain group and the Lagonaki plateau. Climate zoning of the above-mentioned mountain territories was performed based on the study of vertical zoning for the black sea and Northern slopes of the Greater Caucasus using data from expedition studies conducted in 2015 and 2016. During the climatic zoning of the mountain territories of the Greater Caucasus, a number of climatic regions were identified that are not included in SP 131.13330.2012. 5 new climatic regions are proposed, which are necessary for the climatic zoning of the black sea and Northern slopes of the Caucasus. Analysis of precipitation distribution has shown that for the black sea slope of the Caucasus (within the territory under consideration) there is a strictly defined dependence of their distribution with the height of the terrain. The same relationship exists for the Northern slope of the Caucasus. As you climb into the mountains, precipitation rates increase. It is important to note that the absolute amount of precipitation and its distribution by height (vertical zoning) for the black sea and Northern slopes are different. A map of the climate zoning of the Greater Caucasus has been compiled. It is proposed to make additions to Appendix B of SP 131.13330.2012.
