按照以上参数设置对自己的namelist.wps文件进行修改。注意geog_data_path = '/home/test/Build_WRF/WPS_GEOG/'一定要换成自己的路径,然后就可以保存后退出(ctrl+s,ctrl+x)。 3.3 运行geogrid.exe之前,确保模拟域在正确的位置 test@test:~/Build_WRF/WPS-4.1$ ncl util/plotgrids_new.ncl 执行完以上代码后,...

Four-dimensional data assimilation (FDDA) was applied in WRF-CMAQ model sensitivity tests to study the impact of observational and analysis nudging on model performance in simulating inversion layers and O3 concentration distributions within the Uintah Basin, Utah, U.S.A. in winter 2013. Observation...
2.2. FDDA The Four-Dimensional Data Assimilation (FDDA) is a nudging scheme designed for the WRF model [19]. It modifies the prognostic equations for wind, humidity, and temperature, by adding a weighted nudging term that leads the model toward the observed state. The detailed description of...
