各位气象前辈:
见贴好!
我是一只还没有入门的WRF 菜鸟。希望各位不吝指教。
我看到有的文献在进行WRF预报时,会先用单层嵌套模拟12小时的数据,然后将这个模拟结果作为正常积分的初始场和侧边界。
例如,某次的观测过程起始于4月3日12时,消散于4月3日20时,于是作者首先用单层嵌套,从4月2日12时开始,积分12小时至3日00时,然后开始第二次计算,积分时间从3日00时到4日00时,,数值,模式,气象数值模式,数值模式,气象模式,海洋模式,气候模式,WRF,MM5,Grapes,HYCOM,LICOM,同化,集合预报,模式联盟,模式论坛8 s; A* G& ~1 F用第一次计算的结果作为二次计算的初始场和侧边界。
我想请教一下各位前辈,具体怎么实现这种操作?第一次的namelist还好设计,第二次的namelist或者运行的命令有何不同呢?
