| 英文摘要 | During 1977-1981 the beijing (bj) meteorological station was at a suburban location. in 1981 it was moved to a more urban location, but in 1997 it was subsequently moved back to the same suburban location. the daily bj temperature series, together with those from 18 nearby stations, form a unique database for studying how site-change and possible urbanisation influences affect climate changes at a local scale. the site-change-induced biases were quantified, between 0.43 and 0.95 degrees c, based on comparisons between multi-year-mean seasonal temperature anomalies at bj and the mean of those from a cluster of nearby stations. the annual mean urban-suburban difference was 0.81 degrees c around 1981 and 0.69 degrees c around 1997, indicating a growing urbanisation effect ill the suburban compared to the downtown area. the linear warming trend in the adjusted (for site moves only) bj temperature series during 1977-2006 was 0.78 degrees c/decade. comparing with several rural and less-urban sites, we suggest that the bj records include an urbanisation-related warming bias between 0.20 and 0.54 degrees c/decade, likely about 0.30 degrees c/decade, for the recent few decades. the climatic warming at bj between 1977 and 2006 is likely, therefore, to be about 0.48 degrees c/decade. caveats for using these estimates were discussed. copyright (c) 2009 royal meteorological society |
