Clouds affect both solar radiation and terrestrial (longwave)
radiation.

|
|
| q |
Typically, clouds increase albedo è
a cooling effect (negative feedback)
|
|
|
clouds reduce outgoing
longwave radiation è a heating effect (positive
feedback)

The net effect of clouds on climate depends cloud types and their
optical

properties, the insolation, and the characteristics of the
underlying surface.
|
|
|
| q |
In general, high clouds tend to produce a heating (positive)
feedback. Low clouds
|
|
|
tend to produce a cooling (negative) feedback.
