Energetics of Climate Models: Net Energy Balance and Meridional Enthalpy Transport
[1] We analyze the publicly released outputs of the simulations performed by climate models (CMs) in preindustrial (PI) and Special Report on Emissions Scenarios A1B (SRESA1B) conditions. In the PI simulations, most CMs feature biases of the order of 1 W m for the net global and the net atmospheric, oceanic, and land energy balances. This does not result from transient effects but depends on th...
متن کاملWhat Determines Meridional Heat Transport in Climate Models?
The annual mean maximum meridional heat transport (MHTMAX) differs by approximately 20% among coupled climate models. The value of MHTMAX can be expressed as the difference between the equator-topole contrast in absorbed solar radiation (ASR*) and outgoing longwave radiation (OLR*). As an example, in the Northern Hemisphere observations, the extratropics (defined as the region with a net radiat...
متن کاملOcean Heat Transport, Sea Ice, and Multiple Climate States: Insights from Energy Balance Models
Several extensions of energy balance models (EBMs) are explored in which (i) sea ice acts to insulate the atmosphere from the ocean and (ii) ocean heat transport is allowed to have some meridional structure controlled by the wind, with minima at which the ice edge can rest. These new models support multiple stable ice edges not found in the classical EBM and a hysteresis loop capable of generat...
متن کاملMeridional Energy Transport: Uncertainty in Zonal Means
The meridional energy transport in the atmosphere and ocean is computed using atmospheric analyses from ECMWF and NMC, and net radiative ux from ERBE. An error analysis of the zonally-averaged total transport shows that errors of 7 Wm 2 in net ux produce transport errors of 0:5PW at the equator, an error of 9% in midlatitudes. Methods for correcting the mass non-conservation in transports deriv...
متن کاملNet radiation with energy balance closure
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Low energy balance closure (EBC) at a particular eddy-covariance flux site increased the uncertainties of carbon, water and energy measurements and thus hampered the urgent research of scaling up and modeling an...
