Bacteria in the ECHAM5-HAM global climate model
Some bacteria are among the most active ice nuclei found in nature due to the ice nucleation active proteins on their surface, which serve as active sites for ice nucleation. Their potential impact on clouds and precipitation is not well known and needs to be investigated. Bacteria as a new aerosol species were introduced into the global climate model (GCM) ECHAM5-HAM. The inclusion of bacteria...

متن کاملCirrus clouds in a global climate model with a statistical cirrus cloud scheme
In addition to the new cirrus cloud scheme described in Sect. 2.2, a prognostic cloud droplet number concentration (nl) equation for liquid clouds is added in the version of CAM3 used in this study compared with the version used in Liu et al. (2007a). Together with the prognostic liquid water mass (ql), ice water mass (qi), and ice crystal number concentration (ni), the complete set of equation...
متن کاملCloud 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 کاملAn improvement on the dust emission scheme in the global aerosol-climate model ECHAM5-HAM
Formulation of the dust emission scheme in the global aerosol-climate modeling system ECHAM5-HAM has been improved. Modifications on the surface aerodynamic roughness length, soil moisture and East-Asian soil properties are included in the parameterization, which result in a large impact on the threshold wind friction velocity for aeolian erosion and thus influence the simulated dust emission a...
