摘要: 利用中尺度模式WRFV2.2,选取其中NOAH陆面模式进行陆面参数随机扰动试验,模拟研究了南京地区2007年7月8—9日的暴雨对扰动的敏感性。结果表明:(1)此次暴雨过程对陆面参数随机扰动较为敏感,其中对土壤最大容积含水量的扰动最为敏感,Abstract: The simulation of the heavy rainfall occurring in Nanjing during 8 ~9 July, 2007 was conducted to test the sensitivity of the rainfall to the random perturbation of NOAH land surface parameters by using WRFV2.2.
