关于EC数值预报资料“云水含量”的高度问题的疑问

wheelar

目前，中国气象局下发的EC数值预报是grib1和grib2混合压缩的，解压grib2时候，有“FRACCC Fraction of Cloud Cover [Numeric]”，“SCLLWC Specific Cloud Liquid Water Content [kg/kg]”，“SCLIWC Specific Cloud Ice Water Content [kg/kg]”三个变量，应该是云量，云水含量和云冰含量，但不是按气压层的，是num hybrid level, num=1 to 137,就是有137个云量数量，请问这个hybrid level是什么意思呢？是EC模式设置的高度吗？

关于数值预报小弟知道的很有限，希望有知道的帮忙解答一下，多谢各位大神！

用wgrib2 -V ec.bin 得到的结果如下：

根据搜索https://confluence.ecmwf.int/display/METV/Relative+Humidity ，hybrid level 应该就是常说的model level, 想用pressure level 需要插值才能得到。

这里可能会对你有所帮助。
