Understanding Cloud Altitude, Depth

Hello,

I've a test scene in which I'm trying to understand the interaction between cloud altutude and cloud depth. It's definitely not self-explanatory.

Using the painted shader as the density:

If I set my depth to something like 2000, but the altitude to 1 or 2, why doesn't a fat cloud hover just above the ground?

If I set the altitude to 1000 and adjust the depth down or up, why does the cloud seem to lose or gain altitude?

Can someone explain the relationship between these two settings? Thanks!

The depth setting works in two directions related to the altitude.
If the cloud altitude is 1000m and the cloud depth is 1000m as well, then the cloud-layer will range from 500 to 1500m.

Altitude at 1 or 2 with a depth of 2000 would put the ground in the middle of the cloud layer. The altitude defines the *middle* point, and the depth is equal above and below that. Martin's example shows that.
