Bumpiness along the flight
Takeoff on the left, landing on the right. The higher the line, the bumpier the air the forecast expects at that moment.
Where, and why
The flight split into stretches: how bumpy each is forecast to be, and what causes it.
PVG · Take off0m – 16mSmooth
Nothing significant forecast here.
The first minutes are flown through the lowest, liveliest air. Sun-warmed ground sends up thermals and wind bends around hills, so a bump or two while climbing is normal. It fades as the aircraft climbs into the smoother air above.
Cruise16m – 29mLight
Jet-stream wind shear
Where fast air slides over slower air, usually at the edge of the jet stream, the boundary ripples like a flag. It is the most common kind of turbulence and it never comes as a surprise: it is on the crew's charts, and they slow to a set turbulence speed and let the aircraft ride it out.
At cruise the air is thin and cold, and most of it is calm. The bumps up here come from the jet stream, a river of fast wind whose edges stir the air, or from waves set off by mountains far below. This forecast maps exactly where those edges sit.

Nothing significant forecast here.
Coming down means flying back through the low, lively air near the ground: afternoon thermals, gusts around the airport. It is the busiest part of the flight for the crew, and the part they train for most.

What each level feels like
- Smooth
- Calm air. Nothing to notice beyond the hum of the engines.
- Light
- Gentle ripples and the odd dip. Drinks stay put, and walking to the toilet is fine.
- Moderate
- Distinct bumps. A drink might slosh and the belt sign comes on. Uncomfortable, and the aircraft is in full control throughout.
- Severe
- Strong jolts, and loose items can move. Rare, and the reason the belt sign exists: crews slow down and change altitude to get out of it.
How this forecast is made
The planned route is sampled from gate to gate at the altitude the aircraft flies, through 3 independent global weather models, and corrected with turbulence reports radioed in by pilots in the last few hours. Each new model run replaces the forecast; nothing here is a guess from the airline's history.
The weather models behind this forecast mostly agree; the bumpy patches may shift a little.
Planned route · timing and conditions may change.
Why the bumps are only bumps
Built for it.
Airliners are tested to loads far beyond anything turbulence produces; the wing flexing you can see is by design.
Seen in advance.
Your crew flies with forecasts like this one, live reports from other pilots and their own weather radar, and they change altitude to stay out of the bumpy air.
The belt is the whole story.
Turbulence injuries almost always involve someone standing or unbuckled. Seated with the belt on, it is a bumpy road and nothing more.
Questions about MU5155
Will MU5155 be bumpy?

Is turbulence dangerous on MU5155?
Turbulence is uncomfortable, not dangerous to the aircraft. Airliners are certified for loads far beyond anything turbulence produces, and crews plan around the bumpy patches with the same kind of forecast as this one. Injuries are almost always to people who were standing or unbuckled, so keep your seatbelt fastened whenever you're seated.
How accurate is this turbulence forecast?
It is a forecast, so it is best within a day or so of departure and improves with every model run. The bumpy patches it finds are usually in the right place, but their timing can shift by a few minutes and the crew may change altitude to avoid them, so the ride you get is often smoother than the forecast.
