How to set up the WRF SST Sensitivity test

尊敬的WRF&MPAS 专家
我 想用WRF对SST做几个灵敏度测试,比如修改某个区域的SST,现在我有两个 问题:
1. SST灵敏度测试应修改哪些文件和变量 ?met_em* 文件中的 SST 还是 wrflowinp、wrfbyd 和 wrfinput 中的 SST? 还是两者都可以?(wrflowinp、wrfbyd 和 wrfinput 必须 更改所有三个或必须更改其中的一些)
2.以这种方式修改SST变量是否合适 。我想改变海面温度 ,看看它是否影响台风强度。
感谢您的帮助!
 
I would suggest that you change SKINTEMP and SST in met_em files. This is because SST and TSK are derived from these variables when running REAL, and these two variables will be used later when running wrf.exe.
 
感谢您的回复。我尝试更改met_em文件中的SST,但由于met_em文件中的SST变量不包含经度和纬度信息,而只包含单元格点,因此当我想更改区域的SST时,我不知道如何确定位置。wrfinput 中的变量包含经度和纬度信息
 
met_em data does include lat/lon information.

XLONG_M and XLAT_M are for SST.

Thank you for your reply. I finally found that the latitude and longitude in the met file are XLAT_M,XLONG_M
