WRF的namelist.input设置

Nozigaka46

请问WRF的namelist.input中，&dynamics模块里面，有一个 etac = **的选项
user_guide里面的描述是“znw(k) < etac, eta surfaces are isobaric (0.2 is a good default)”


那这个选项主要是调整什么内容的？还是没有看懂

It looks like etac is the "critical eta level" or the eta level at which the WRF model surfaces become completely isobaric. The default value is 0.2. You can try adding it to the &dynamics section of your namelist, and setting it to something like 0.1 and see if that works better for you. Take a look in the WRF/doc/ directory and you can read more about this variable in the README.hybrid_vert_coord file.
