ask help about Sea Ice data for Polar WRF

[CUIyige]

我目前正在研究 Polar WRF，但我在使用它时遇到了问题。我尝试使用 ERA5 的 SEAICE 数据。为了探究海冰对温度的影响，我的想法是保留和删除Vtable中的海冰线，但对比结果没有变化，说明我的海冰没有起到作用。我的底层曲面使用了 modis 数据。我问你，我的底层表面数据是否有问题，或者我所做的不合适。我真诚地期待您的回复，非常感谢您。

First of all, please post your questions in English.

It is not unexpected that you see no differences with and without seaice in your intermediate files. This is because WRF will adjust the landuse type over ocean depending on SST, i.e., if SST is colder than the threshold (271.3?), then the open ocean is changed to seaice.
To conduct the sensitivity tests you intend to do, it is not sufficient to change seaice. You will have to modify the codes to ensure that even if SST is very cold, the ocean still remains open.

Sorry teacher, thank you for your reply. I didn't notice the language issue when asking questions. SST is cold than the threshold (271.3?), Then the open ocean is changed to sea. I'm really sorry. Regarding the specific code you mentioned, how should I modify it,
