What controls the total heat transport in CMIP3 models Aaron Donohoe AGU 2010 – 12/12/2010
2
Heat Transport Spread In Climate Models Observations Peak Heat Transport Histograms
3
Understanding heat transport 5.7 PW Heat Transport = - 8.1 PW 2.4 PW ASR*OLR*
4
Model heat transport spread in terms of OLR* and ASR*
5
Understanding ASR*
6
Heat transport and planetary albedo
7
What determines the amount of solar radiation reflected at the top of the atmosphere? Earth’s Surface Atmosphere Solar Incident Reflected by Atmosphere Reflected by Surface
8
Zonal Mean Planetary albedo partition (observations are dark models dotted and light).
9
Heat transport and cloud reflection
10
Conclusions The model spread in heat transport is due to gradients in net solar radiation (ASR*) Gradients in net solar radiation are due to gradients in Planetary Albedo Gradients in Planetary Albedo are due to the simulated cloud distribution Cloud’s determine Heat Transport We explained a dynamic quantity without invoking dynamics- do dynamics play an active or passive role in determining the radiative fields?
