英文摘要 | Oxygen stable isotope of atmospheric water vapor is widely used to study the modern process of climate. Atmospheric water vapor samples were collected at Dlingha, northeast of Tibetan Plateau during the period from July 2005 to February 2006. The variation of delta O-18 and the relationships between delta O-18 and both the temperature and specific humidity are analyzed in this paper. Results show that the seasonal variation of delta O-18 of atmospheric water vapor at Delingha is remarkable with higher delta O-18 in summer and lower delta O-18 in winter. The temporal variation of vapor delta O-18 shows obvious fluctuations, with magnitude of over 37 parts per thousand The daily variation of the delta O-18 is highly correlated with air temperature. The relationship between delta O-18 and atmospheric water vapor content is complex. Study shows that delta O-18 of atmospheric water vapor is positively correlated with specific humidity in winter in seasonal scale and inversely correlated with specific humidity in summer rainy period. The delta O-18 values of atmospheric water vapor are lower than those of precipitation at Delingha, and the average difference is 10.7 parts per thousand Variations of delta O-18 of atmospheric water vapor is also found to be affected by precipitation events, The model results show that the precipitation effect could have caused the vapor delta O-18 in the raining season to lower by 7% in average in July and August. |
