To make your turbulence smoother, reducing the octave parameter could
help. It default at 6. So, maybe try with octave 3.
Next, you can also reduce the lambda. Default of 2. Make it closer to 1.
Finally, the omega could also get adjusted down from the default of 0.5.
A proposition :
octave 3
lambda 1.4
omega 0.25
This should make the turbulence much more wavy and smoother.
