[Characteristics of Stable Isotope in Precipitation and Its Relationship with ENSO in Shanghai].

A total of 70 precipitation samples were collected from August 2014 to August 2015 in Shanghai and the oxygen and hydrogen isotope of precipitation were analyzed. The relationship between the δO and deuterium excess of precipitation and ENSO events was addressed. The results showed that δD and δO of precipitation in Shanghai were higher in winter and spring than in summer and fall.
