A Climatological Interpretation of Precipitation δ 18 O across Siberia and Central Asia
Siberia and Central Asia are located at middle to high latitudes, encompassing a large landlocked area of the Eurasian continent and vast tracts of permafrost, which are sensitive to global climate change. Here, we investigated the data from 15 Global Network of Isotopes in Precipitation (GNIP) stat...

Siberia and Central Asia are located at middle to high latitudes, encompassing a large landlocked area of the Eurasian continent and vast tracts of permafrost, which are sensitive to global climate change. Here, we investigated the data from 15 Global Network of Isotopes in Precipitation (GNIP) stations to clarify the relationship between precipitation δ 18 O (δ 18 O P ) and the local temperature and precipitation amount on the monthly, seasonal, and annual timescales. Three main conclusions as following: (1) On the monthly time scale, the variation in δ 18 O P is mainly controlled by the “temperature effect”. (2) The weighted average value of precipitation δ 18 O (δ 18 O w ) exhibited “temperature effect” over 60° N–70° N.
