WRF使用4层嵌套模拟,运行一段时间后报错,仅某个rsl.error报错如下:
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:

然后rsl.out文件中末尾都是如下表示:

最内层的时间步未0.5s,初步猜测不是时间步的问题导致的数值不稳定,在国外网站看到说是可能物理方案不兼容。。但是都运行起来了很长时间才报错的。不知道是不是namelist.input的错误。贴下namelist的设置,希望大家帮忙看看哪里出了问题,我已经卡在这里很多天了,一直在尝试,总是失败。。。。。
