大家好,我在做WRFDA的cycle模式的时候,分别在0点、6点、12点和18点进行资料同化,转到6点先根据手册更新WRFOUT的下边界,然后做DA的同化,再更新测边界,再运行下一个6小时的数据;但是我现在的模拟结果有些问题,我感觉在我循环的时刻,模式重新启动了,而不是接着上一个小时继续转;例如下面是个某个站点的数据值,在0、6、12、18时刻都像是模式重启了;time,pm25(ug/m3),pm10(ug/m3),o3(ug/m3),no2(ug/m3),co(mg/m3),so2(ug/m3)

我在阅读官网手册时,在第二个时刻,也就是我模式的1日的6点,需要更新下边界,官网中的parame.in如下所示,那他的./fg 原本链接的是0点的wrfinput_d01,我在做的时候在第二个时刻更换为6点的wrfinput_d01,但[size=13.3333px]wrf_input已经给了[size=13.3333px]wrfinput_d01输入文件了,为什么还需要再链接一个相同的呢,或者说我没理解对这个da_file应该链接的文件是什么
da_file = './fg' wrf_input = './wrfinput_d01' update_lateral_bdy = .false. update_low_bdy = .true. iswater = 16
