Aerosol nucleation and its role for clouds and Earth's radiative forcing in the aerosol-climate model ECHAM5-HAM
Aerosol nucleation clouds and Earth's radiative forcing the aerosol-climate model ECHAM5-HAM
2010/11/30
Nucleation from the gas phase is an important source of aerosol particles in the Earth's atmosphere, contributing to the number of cloud condensation nuclei, which form cloud droplets. We have impleme...
Estimation of ECHAM5 climate model closure parameters with adaptive MCMC
ECHAM5 climate model closure parameters adaptive MCMC
2010/11/3
Climate models contain closure parameters to which the model climate is sensitive. These parameters appear in physical parameterization schemes where some unresolved variables are expressed by predefi...
Stratospheric water vapour and high climate sensitivity in a version of the HadSM3 climate model
Stratospheric water vapour high climate sensitivity the HadSM3 climate model
2010/8/16
It has been shown previously that one member of the Met Office Hadley Centre single-parameter perturbed physics ensemble – the so-called "low entrainment parameter" member – has a much higher climate ...
A comparison of ship and satellite measurements of cloud properties with global climate model simulations in the southeast Pacific stratus deck

2010/8/16
We examine the response of the Met Office Hadley Centre's HadGEM2-AO climate model to simulated geoengineering by continuous injection of SO2 into the lower stratosphere, and compare the results with ...
Cirrus clouds in a global climate model with a statistical cirrus cloud scheme
Cirrus clouds a global climate model a statistical cirrus cloud scheme
2010/8/13
A statistical cirrus cloud scheme that accounts for mesoscale temperature perturbations is implemented in a coupled aerosol and atmospheric circulation model to better represent both subgrid-scale sup...
Quantitative assessment of Southern Hemisphere ozone in chemistry-climate model simulations
Quantitative assessment Southern Hemisphere ozone chemistry-climate model
2010/2/21
Stratospheric ozone recovery in the Southern Hemisphere is expected to drive pronounced trends in atmospheric temperature and circulation from the stratosphere to the troposphere in the 21st century; ...
Comparison of a global-climate model simulation to a cloud-system resolving model simulation for long-term thin stratocumulus clouds
global-climate model cloud-system resolving model long-term thin stratocumulus clouds
2009/9/14
A case of thin, warm marine-boundary-layer (MBL) clouds is simulated by a cloud-system resolving model (CSRM) and is compared to the same case of clouds simulated by a general circulation model (GCM)....
