Variations of the δ18О values and water-soluble salts in precipitation in Moscow during 2014 to 2016
Abstract
Samples of precipitation representing all precipitation events were collected at the Meteorological Observatory of the Lomonosov Moscow State University during 2014–2016, namely 101 samples in 2014; 140 samples in 2015; 154 samples in 2015. Amount and duration of precipitation, air temperature in the surface layer of the atmosphere, pH, ionic and isotope composition of precipitation samples were measured. Distribution of δ18О values in precipitation in 2014–2016 is of a sinusoidal type, they also correlate well with changes of temperature. In general, average monthly δ18О values increase from January to May-July. During the 3-year period, the most isotopically depleted precipitation occurred in January, and the most isotopically enriched precipitation occurred during summer months. The correlation coefficient of the oxygen isotope composition with the air temperature was 0,96 in January and 0,99 in June-August. Anomalously enriched precipitation in November 2014 could be explained by both higher air temperature, and the changes in the movement of the air mass front. The highest mineralization of precipitation during the study period was in 2014, mainly because of the low amount of precipitation. In wetter 2016 the average mineralization was almost 2,5 times lower than in 2014–2015. The predominant ions in 2014–2016 precipitation were chlorine and calcium. The maximum values of mineralization and ion concentrations were observed from March to May.
