Professional Ethics for Civil and Structural Engineers under the German Law Governing the Profession of Engineers
Publisher: American Society of Civil Engineers
Competition of Precipitation Particles in a Model with Parameterized Cloud Microphysics
Publisher: American Meteorological Society
Abstract: The nonlinear open system cloud is analyzed in this basic study in the context of the theory of self-organization. Emphasis is placed on the microphysical processes of riming, accretion, and sedimentation in a supercooled ...
Possible Aerosol Effects on Ice Clouds via Contact Nucleation
Publisher: American Meteorological Society
Abstract: The indirect effect of aerosols on water clouds, whereby aerosol particles change cloud optical properties, is caused by aerosol-induced changes of the size and number of cloud droplets. This affects the lifetime of the ...
Vertically Resolved Convective–Stratiform Echo-Type Identification and Convectivity Retrieval for Vertically Pointing Radars
Publisher: American Meteorological Society
Abstract: Using data from the airborne HIAPER Cloud Radar (HCR), a partitioning algorithm (ECCO-V) that provides vertically resolved convectivity and convective versus stratiform radar-echo classification is developed for vertically ...
Constraining Precipitation Susceptibility of Warm-, Ice-, and Mixed-Phase Clouds with Microphysical Equations
Publisher: American Meteorological Society
Abstract: he strength of the effective anthropogenic climate forcing from aerosol?cloud interactions is related to the susceptibility of precipitation to aerosol effects. Precipitation susceptibility d lnP/d lnN has been proposed ...
A Comparison of Tropical and Midlatitude Thunderstorm Evolution in Response to Wind Shear
Publisher: American Meteorological Society
Abstract: The influence of vertical wind shear on storm development within a tropical environment is studied with the aid of two numerical models and compared with that in simulations of midlatitude storms. The simulations show that ...
Sensitivity Studies of Aerosol–Cloud Interactions in Mixed-Phase Orographic Precipitation
Publisher: American Meteorological Society
Abstract: Anthropogenic aerosols serve as a source of both cloud condensation nuclei (CCN) and ice nuclei (IN) and affect microphysical properties of clouds. Increasing aerosol number concentration is assumed to retard the cloud ...
Effect of Synoptic Systems on the Variability of the North Atlantic Oscillation
Publisher: American Meteorological Society
Abstract: The North Atlantic Oscillation (NAO) represents the dominant mode of atmospheric variability in the North Atlantic region. In the present study, the role of the synoptic systems (cyclones and anticyclones) in generating ...
A Consistent Diffusion–Dissipation Parameterization in the ECHAM Climate Model
Publisher: American Meteorological Society
Abstract: The diffusion?dissipation parameterizations usually adopted in GCMs are not physically consistent. Horizontal momentum diffusion, applied in the form of a hyperdiffusion, does not conserve angular momentum and the associated ...
Nonlinear Horizontal Diffusion for GCMs
Publisher: American Meteorological Society
Abstract: The mixing-length-based parameterization of horizontal diffusion, which was originally proposed by Smagorinsky, is revisited. The complete tendencies of horizontal momentum diffusion, the associated frictional heating, and ...
