Uncertainty in the jet response to climate change is affected by parameterized convection, as this recent study indicates:

It is usually assumed that all components of the midlatitude circulation shift together in response to climate change. In my recent paper it is shown that diabatic heating is associated with a decoupling between the eddy heat flux and jet latitudes:
