摘要

Based on the extreme climate index method issued by World Meteorological Organization, 12 indices of Jiamusi during 1951-2010 were evaluated, and the extreme climate events and their variations were obtained. The results showed that in recent 60 years, summer days (SU), extremely minimum temperature (TNN), extremely maximum temperature (TXX), warm nights (TN90) and warm days (TX90) displayed a significantly increasing tendency, while frost days (FD), cold nights (TN10) and cold days (TX10) showed a decreasing tendency. Changing trends of the all precipitation indices were not significant. The extremely low temperature events and extreme strong precipitation were related with El Nino.
