Abstract:

By linear interpolation approach and RHtest procedure, a serially completed and homogeneous daily maximum temperature dataset of 853 meteorological stations during 1961-2010 in Eastern Forest Region (EFR) in China was established. Based on the dataset, an analysis on the change characteristics of the maximum temperature prior to and after adjustment was carried out. The results showed that the adjusted maximum temperature data series had an average warming trend of 0.171, 0.233,-0.002, 0.201 and 0.263℃ per 10 years on annual and four seasonal (spring, summer, autumn and winter) timescales, respectively. On annual scale, the adjusted annual maximum temperature all exhibited a warming trend, while the annual maximum temperature prior to adjustment had a cooling trend for several meteorological stations. Spring, autumn and winter showed a warming trend almost everywhere in EFR, while summer had a cooling trend in most stations, especially in the regions between Yangtze River and Yellow River within the EFR.

Key words: daily maximum temperature, interpolation of missing record, homogenization adjustment, RHtest, climate change, eastern forest region(EFR) of China
