      摘要: 選用英國Hadley中心的RCM-PRECIS模式進(jìn)行江淮流域氣候變化的數值模擬。在驗證了PRECIS在江淮流域模擬能力的基礎上,對未來(lái)CO2增加后江淮流域的氣候變化響應進(jìn)行了預估。結果表明:在B2情景下,整個(gè)江淮流域都將繼續增暖,到本世紀末(2071-2100年)區域年平均溫度將增加2.9℃,夏季將可能出現更多的高溫事件,而冬季極端低溫事件減少;降水量呈增加趨勢,強降水(尤其是120 mm以上的降水)日數也將增多。

      Abstract: A regional climate model (PRECIS), developed by the UK' Hadley Center for Climate Prediction and Research, was used to simulate the climate in the Changjiang-Huaihe River valley. PRECIS'capacity for simulating present climate over the valley was firstly validated by comparing the simulations of temperature and precipitation with the observations during 1961-1990; the model was then used to project the climate change over 2071-2100 in the valley. The results give a regional annual average surface warming of 2.9℃ and a somewhat increase in precipitation under the SRES B2 emission scenario by the end of the 21st century (2071-2100). The results also present more extremely high temperature events during summer and fewer extremely cold events during winter. The number of days with heavy rain (especially above 120 mm/d) will be likely to increase.

      Key words: climate change, regional climate model, PRECIS, CO2, projection
