Turbulence on the ICN → LAX route

Jet-stream exposure on this corridor is significant. Long mid-latitude legs mean clear-air turbulence is the dominant source of bumps, typically encountered at cruise altitude. The route crosses or passes near the Rocky Mountains, which can generate mountain-wave turbulence downwind when upper-level winds are strong. Flying eastbound, aircraft usually benefit from tailwinds near the jet core, which trims flight time - but the edges of the jet are where clear-air turbulence most often sits.

Calmest season: Late spring to early autumn (May-September). This corridor is most turbulent in the northern winter (Nov-Mar), when the jet stream is strongest and sits closer to the route. Wind flowing over the Rocky Mountains can generate mountain-wave turbulence that extends hundreds of kilometres downwind - most pronounced in the northern winter (Nov-Mar), when upper-level winds are strongest.
