We have talked a lot about airplanes climb rates, but does a low climb rate mean more turbulences in bad weather conditions? I mean, if the plane climbs slowly, it will stay longer in turbulent clouds!What do you think?

Quoting Warren747sp (Reply 1): Of course, the sooner you can clear the clouds layers,etc. the sooner you have smoother air
Clouds aren't always turbulent. Some of the worst turbulence is in the clear air around a jetstream, found at higher altitudes.
There's no point in climbing fast if you're only going up into a turbulent layer.

The importance here is not how fast or slow you get out of turbulent air but how FAST the airplane flies through it and the effect the speed has over the structure.
Most airplanes have a turbulence penetration speed. One which guarantees the structural integrity of the aircraft, provides stall safety margins and gives most passenger comfort. It is often slower than the regular cruising and fast climb mode speed, so in order to achieve it, pilots have to decrease speed in level flight, or if they are climbing increase the rate of it keeping the same amount of thrust to make the speed decrease a bit and obtain the desired turbulent or maneuvering speed.
There are no stupid questions... just stupid people!

Exactly, you have answered your own question there.

Hmm..., I would see no point in delaying the climb rate if that was the case. ATC require a certain rate of climb (especially in busy airspace) to meet level restrictions on the way up. By purposely climbing in a slow rate you would firstly be using much more fuel and secondly you would be flying the aircraft in an uneconomical way, a way that it wouldn't like to be flown.
