Quick question: Does flying around or in the Jetstream mean a bumpy ride or not? Im curious about the effects the jetstream has on Turbulence.

Quoting LAXdude1023 (Thread starter):

Short answer: yes

Flying with the jetstream...higher ground speed, some turbulence

Flying into the jetstream...lower ground speed, some turbulence

Flying across the jetstream...turbulent

If you are flying inside the Jet Stream, there should be little or no turbulence. However this is not the case if you are flying on/through either boundary, where there can be (usually is) a difference in air layer speeds. When there are significant differences between Jet Stream air speed and it's surroundings, wind shear conditions can occur causing major turbulence.

So traveling with the Jetstream doesnt produce much turbulence, but crossing it does? What about exiting/entering the jetstream?

Nearly any time you have a sudden, drastic change in wind direction and velocity you'll have turbulence.

You can't say ALWAYS regarding turb but the location of usually the worst jetstream turb is the upper and lower northern quadrants.

Jetstreams are associated with great pressure and temperature differences, and the gradient close to the jetstream (temp. or pressure difference per unit of distance) is greater that further away. So when crossing or "catching" the jetstream, and sometimes in the jetstream itself, you can experience CAT (clear air turbulence).

One of the keys about the jet is to be aware of where the trop is located. Flying +/- 2000 away from the trop will "generally" give you a pretty smooth ride. As CosmicCruiser pointed out nothing is certain regarding the jet, but there are some places to avoid if possible.
