Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences
in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal
changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a
change in surface or atmospheric conditions and the
change in cloud radiative properties
associated with a
change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between
surface air
temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.
