华南沿海近100年气温上升速率估算

Estimation on the Warming Rate at South China Coastal Areas over Last 100 Years

采用华南沿海气象站气温资料，在排除城市热岛效应的基础上，分析近50年、近100年地表气温的变化趋势，得出华南沿海近51年（1953—2003年）的平均增温速率为0．12℃／10年，近100年（1905—2004年）的增温速率为0．6—0．8℃／100年，均与同时期的北半球（陆地＋海面）平均增温速率相近。

Instrumental climatic data from some meteorological observatories of the South China were used to analyze the changing rates of surface air temperatures over last 50 years and 100 years respectively. The impact of anthropogenic greenhouse gas （ or the contribution from urbanization） was removed by comparing to the records from coastal observatories with little human activity influence. The results indicate that the warming rate was 0.12 ℃ /10ys for the period of 1953 -2003, and 0.6 -0.8℃/100ys for the period of 1905 - 2004, which are in agreement with the average land and sea values of Northern Hemisphere at the same period.
