Is there a name for where the sky and the cloud line meets?

I was recently flying from Maui to California and we were up above the clouds. I got to see dawn break when I was over the clouds. But then I realized that the line where the clouds and sky met, where the light was coming from, was not the horizon. What would it be called if anything?Is there a name for where the sky and the cloud line meets?
You could be talking about the tropopause. It's the boundary between the troposhpere and stratosphere. Most weather takes place in the troposhpere so comercial jets usually fly above it.Is there a name for where the sky and the cloud line meets?
That is called the "horizon".Is there a name for where the sky and the cloud line meets?
Horizon
The old professor says: No special word needed. "Cloud tops" will suffice. The sun would appear to arise over the cloud tops.
