There are NAN values in the output of the output.rch, ouptput.std. I checked the results and found that the PET in November 2021 are NaN values. So, I checked the tmpa.tmp file. I have taken many hours to ensure that the file in the corresponding month (2021) is right. But,all effort just in vain.[……]

1. Because the Field of the date can’t be named as DATE (Arcgis reserved characters). Thus, we must use the existed file. But if the rows of our data is longer than the existed file, how[……]
SWAT模型不同气象条件的配置
在进行气候变化的水文响应分析时，我们常常需要在swat模型中更新气象数据，然后模拟不同气象条件下的水文响应差异。当然，很直接的方法是在arcswat中重新加载新的气象数据，然后进行一步一步设置进行模拟即可，但这样很费时间，所以这里我讲一种较简单的方法。例如1980-1989和1990-1999两个不同的气象条件进行模拟，其它条件一样。分两步模拟后期的水文过程:
第一步，将前期的txtinout文件夹复制出来，粘贴到后期的文件夹中
第二步，将后期生成的气象数据如.pcp文件，.wnd,.hmd等等，复制并覆盖到后期的文件夹中。这里后期的气象数据也是通过arcswat加载生成的。[……]
