I used to teach Met in Vancouver, and this question reminds me of the hrs and hrs prepping for the endless stream of " Good Questions"
The answer : The egg came first!!
Not going there, sorry!
With regards to clear air turbulence it does fascinate me that I can ride a Jet-stream with 100kts for hrs with NO turb whatsoever.
And other times crossing an area with wind less then 15 kts with constant light chops.
Go figure.
OP, I bite. With the POTENTIAL for cloud , the mixing associated with turbulence will create the strati cloud.
A stratiform cloud does NOT necessarily equal turbulence.
A convective DOES , due updrafts, turbulent flow , and potential eventual downdrafts!
Class Dismissed.
