Isotopic Signature of Precipitation in the Elbrus Region

Results of studying isotopic characteristics of precipitation at the foot of the southern slope of Elbrus, in the Caucasus, are presented. The precipitation sampling was organized at Azau station (at an altitude of 2300 m) on an everyday basis. The main precipitation sources for the Elbrus region ha...

Description
Summary:Results of studying isotopic characteristics of precipitation at the foot of the southern slope of Elbrus, in the Caucasus, are presented. The precipitation sampling was organized at Azau station (at an altitude of 2300 m) on an everyday basis. The main precipitation sources for the Elbrus region have been established using the method of HYSPLIT back trajectories. Values of δ 18 O of the precipitation reflect a pronounced relation to the temperature of the surface air layer: Δδ 18 O/Δ T  = 0.85‰/°C.
