小白转WRF又遇到问题了,厚脸皮再求教大家。是这样的,我想看看usgs和modis两种下垫面数据下转出的结果有无大的差别,就用它们分别转了一下,只调了geo_data_res和num_land_cat = 20,其余条件都不变,物理参数化方案,只有长短波选了RRTM和DUHIA,其他方案都是默认(没采用)。
转出来后,USGS的地面气压PSFC不随时间变化,定常的,其余基本气象要素正常;MODIS的就严重得多,降水rainnc+rainc一直为constant field=0,没有下雨,而事实上我模拟的是一次暴雨,其余所有基本气象要素都是不随时间变化的定常场,我的namelist.wps,namelist.input和namelist.arwpost如下,麻烦大神给找找原因,先谢了:
