| 摘 要： | 引进国家气候中心业务化的区域气候模式RegCM_NCC,通过操作系统调试、模拟区域确定、模式分辨率调整等本地化工作,初步建立了针对东北地区的区域气候模式系统,并应用该模式以夏季为例,对东北地区的气候进行了15 a(1991—2005年)时间长度的数值积分试验。结果表明:模式对环流特征和东北地区地面气温具有一定的模拟能力,对气温模拟存在系统性的暖偏差,对降水模拟能力较差。

| Abstract: | The regional climate model RegCM_NCC operated was introduced into Northeast areas from National Climate Center. Regional climate model system was set up for Northeast areas by localization scheme such as operation system debugging, simulation regions determination and model resolution adjustment etc.. Climate in Northeast areas from 1991 to 2005 was simulated by numerical integration experiment based on the localization regional climate model. The results indicate that the model could simulate the regional characteristics of atmospheric circulation and ground air temperature in some extent. However, there exist systematic warm biases for air temperature simulation. The simulation results of precipitation are worse. |
