The plane cuts the clouds

Wingtip vortices can create this effect of a jet plowing through the clouds

Wingtip vortices

Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift.[1] One wingtip vortex trails from the tip of each wing. Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips. Indeed, vorticity is trailed at any point on the wing where the lift varies span-wise (a fact described and quantified by the lifting-line theory); it eventually rolls up into large vortices near the wingtip, at the edge of flap devices, or at other abrupt changes in wing planform.
