AS sensitivity study of the mesoscale characteristics of squall-line systems to environmental conditions: Implication of anvil cirrus parameterization

PDF Version Also Available for Download.

Description

Cloud-radiation feedback has been identified as the single most important effect limiting general circulation models (GCMs) to further progress in climate change research, and regarded as major uncertainties in estimating the impact of increasing concentrations of green house gases on climate simulations. Therefore, it is crucially important to further understand the physical processes involved in order to improve the representation of cloud processes in GCMs. To this end, a cloud resolving model with enhanced model physics was used to study the impact of microphysics, long-and shortwave radiation on mediated and tropical mesoscale convective systems (MCSs). The objective of this work ... continued below

Description

Cloud-radiation feedback has been identified as the single most important effect limiting general circulation models (GCMs) to further progress in climate change research, and regarded as major uncertainties in estimating the impact of increasing concentrations of green house gases on climate simulations. Therefore, it is crucially important to further understand the physical processes involved in order to improve the representation of cloud processes in GCMs. To this end, a cloud resolving model with enhanced model physics was used to study the impact of microphysics, long-and shortwave radiation on mediated and tropical mesoscale convective systems (MCSs). The objective of this work is to parameters the large- scale effects of an important sub-GCM-grid-scale process associated with the titling structure of MCSs. The objective of this work is to parameters the large-scale effects of an important sub- GCM-grid- scale process associated with the titling structure of MCSs. To this end, our primary interest focuses on MCSs in an environment with substantial wind shear, such as squall-line systems, since they have longer lifetimes and wider coverage to affect the earth- atmosphere radiation budget and climate.
