求助 fnl 1x1数据的一个变量

zya570419

这就是根据上一帖的地址下载的fnl   1x1资料的变量

我想寻找某个时段的总的降水量，只找到一个与降水有关的变量  
这是个积云降水？还是总的降水量？有什么区别

PWATclm  0 54,200,0 ** atmos column Precipitable water [kg/m^2]

西南反气旋

这个好像是云中的含水量，它并不能反映降水量的多少，只能表示降水的可能性大小，要某时次的降水量，应该找专门的降水资料，比如降水的观测资料

PWAT 是整个气柱中水汽总量。

可惜我还不会下载啊

正如2、3楼所说，那个是水汽柱含量.
