GRAPES-MESO 模式浅对流参数化的改进与试验OA北大核心CSCDCSTPCD
An improvement of the shallow convection parameterization scheme in the GRAPES-Meso
参考 Berg 等2005、2013年提出的扰动对流触发函数方法,对 GRAPES-Meso 模式积云对流参数化方案(KF eta)中的浅对流激发进行改进设计和试验,将单一的温、湿度触发改为对近地层进行一组温度、湿度扰动后的触发,并且用与该组扰动相关的边界层温、湿度分布确定的联合概率密度函数(JPDF)来表征浅对流云的特征参量及计算浅对流的强度。着重分析了改进方案的浅对流激发、浅对流对环境场的反馈、模式地面降水和2 m 气温的相关响应等,并与原方…查看全部>>
An improvement on the trigger function of the shallow convection scheme in the GRAPES-Meso has been designed and tested referring the treatment suggested by Berg,et al (2005,2013),in which the trigger function is related to the distri-bution of temperature and humidity in the convective surface layer determined by the Joint Probability Density Functions (JP-DF).The results show that more shallow convection could be triggered and occur in an earlier sim…查看全部>>
