WRF运行问题：

报错类型：RIBX never exceeds RIC, RIB(i,kte) = NaN THETAV(i,1) = NaN MOL= NaN TCONV = 0.0000000E+00 WST = NaN KMIX = 1 UST = NaN TST = NaN U,V = NaN NaN I,J= 138 1

特别注意：expr测试队列运行作业限制1小时，超时被杀
注：首先查看rsl.error.xx和rsl.out.xx日志，里面会有详细的报错信息
原因：溢出，namelist.input中时间步长time_step改小

请问我改小了时间步长仍然报同样的错误是怎么回事？

不断调小步长可能是一个解决方案，至少对于我的情况可行。

我的运行情景描述：
我的模拟区域网格大小54km，自定义垂直高度 (eta_level，如下所示)后，出现了报错“RIBX never exceeds RIC, RIB(i,kte) = 0.0000000E+00 THETAV(i,1) = NaN MOL= NaN TCONV = 0.0000000E+00 WST = NaN KMIX = 10 UST = NaN TST = NaN U,V = -0.6185105 -7825.445 I,J= 20 21”

eta_levels = 1.000, 0.9995, 0.999,  0.998,
                                       0.995,  0.993,  0.9922,  0.991,
                                       0.989,  0.985,  0.983,   0.980,
                                       0.978,  0.965,  0.960,   0.955,
                                       0.945,  0.924,  0.920,   0.910,
                                       0.904,  0.848,  0.840,   0.800,
                                       0.747,  0.646,  0.600,   0.580,
                                       0.545,  0.444,  0.420,   0.370,
                                       0.343,   0.242,  0.141,  0.091,
                                       0.061,  0.020,  0.010,   0.000,

自定义设置垂直高度之前是可行的，层数也一致，为40。

解决方案
将time_step不断调小，从90->60->15，最终绕过报错。
