通过两组区域气候模拟数值实验,检验了RegCM3对三江平原下垫面变化的敏感性.结果表明,在10 km×10 km分辨率下,在每组气候模拟数值实验中,只改变三江平原下垫面地表数据,对比不同下垫面的气温和降水量的模拟结果,发现其差异明显,特别是在下垫面地表数据明显变化的地方.这说明RegCM3对三江平原下垫面改变具有很高的敏感性,可以使用该模式对下垫面变化的三江平原区域气候进行数值模拟.
通過兩組區域氣候模擬數值實驗,檢驗瞭RegCM3對三江平原下墊麵變化的敏感性.結果錶明,在10 km×10 km分辨率下,在每組氣候模擬數值實驗中,隻改變三江平原下墊麵地錶數據,對比不同下墊麵的氣溫和降水量的模擬結果,髮現其差異明顯,特彆是在下墊麵地錶數據明顯變化的地方.這說明RegCM3對三江平原下墊麵改變具有很高的敏感性,可以使用該模式對下墊麵變化的三江平原區域氣候進行數值模擬.

Numerical simulation is an effectual method to understand the climate effect of the underlying surface.The sensitivity of RegCM3 to the underlying surface changes in the Sanjiang Plain was verified through two groups of numerical experiments.The results showed that the differences were obvious in both of the numerical experiments when the underlying surface was changed merely at 10 km resolution,the differences of the simulations results were biggest where the underlying surface was changed most intensively.It indicated that the sensitivity of RegCM3 to the underlying surface changes in the Sanjiang Plain was high,and RegCM3 could be used to simulate the regional climate in the Sanjiang Plain.
