      摘要: 利用用于IPCC第四次評(píng)估報(bào)告的全球氣候模式產(chǎn)品,驗(yàn)證其對(duì)重慶地區(qū)最大連續(xù)5 d降水(R5d)的模擬能力的基礎(chǔ)上,對(duì)模擬能力較好的模式進(jìn)行組合,預(yù)估溫室氣體排放高(A2)、中(A1B)、低(B1)3種情景下未來21世紀(jì)重慶地區(qū)R5d的變化。與目前(1980-1999年)氣候相比,不同情景下21世紀(jì)重慶地區(qū)R5d均可能增加,尤其是21世紀(jì)后期相比21世紀(jì)前、中期增加更為顯著。

      Abstract: The extreme precipitation index (R5d) over Chongqing for the 21st century projected by the global climate system models participating in the fourth assessment report of IPCC under the SRES A2, A1B and B1 scenarios has been analyzed in this paper. The results show that compared to the current (1980-1999) climate , R5d over Chongqing will increase in most time of the 21st century under the three SRES scenarios. Especially, R5d will increase more significantly in the later 21st century than in the early and middle 21st century.

      Key words: maximum consecutive 5-day precipitation amount, global climate model, simulation, projection, Chongqing
