Cloud microphysics and aerosol indirect effects in the global climate model ECHAM5-HAM
The double-moment cloud microphysics scheme from ECHAM4 that predicts both the mass mixing ratios and number concentrations of cloud droplets and ice crystals has been coupled to the size-resolved aerosol scheme ECHAM5HAM. ECHAM5-HAM predicts the aerosol mass, number concentrations and mixing state. The simulated liquid, ice and total water content and the cloud droplet and ice crystal number c...

متن کاملAssessment of the Regional Climate Model Version 3 over the Maritime Continent Using Different Cumulus Parameterization and Land Surface Schemes
This paper describes an assessment of the Regional Climate Model, version 3 (RegCM3), coupled to two land surface schemes: the Biosphere–Atmosphere Transfer System, version 1e (BATS1e), and the Integrated Biosphere Simulator (IBIS). The model’s performance in simulating precipitation over the Maritime Continent was evaluated against the 3-hourly Tropical Rainfall Measuring Mission (TRMM) Multis...
متن کاملNew cloud parameterization with relative dispersion in CAM5.1: model evaluation and impacts on aerosol indirect effects
Aerosol-induced increase of relative dispersion of cloud droplet size distribution ε exerts a warming effect and partly offsets the cooling of aerosol indirect radiative forcing (AIF) associated with increased droplet concentration by increasing the cloud droplet effective radius (Re) and enhancing the cloud-to-rain autoconversion rate (Au) (labeled as dispersion effect), which can help reconci...
متن کاملTesting a Cumulus Parameterization With a Cumulus Ensemble Model in Weak Temperature Gradient Mode
This paper prototypes a method for calibrating a cumulus parameterization against a cumulus ensemble model. The key to this technique is to run the cumulus model and the parameterization in identical test cells which provide forcing typical of that seen over tropical oceans. In particular, the mean temperature pro le is relaxed to a reference pro le which is assumed to be characteristic of the ...
