چکیده

This study is a part of the Atmospheric Radiation Measurement (ARM) Program single-column model (SCM) intercomparison project, which compares the performance of various SCMs and cloud ensemble models (CEMs) with ARM intensive observation period (IOP) data sets. The goal of this project is to improve the representations of cloud formative/dissipative processes in general circulation models (GCMs). The approach of SCMs and CEMs for achieving such a goal has been reviewed by Randall et al. (1996).

Explicit Simulation of Midlatitude Cumulus Ensembles: Comparison with ARM Data

This study describes some results from several simulations of cumulus ensembles at the Southern Great Plains site of the Atmospheric Radiation Measurement (ARM) program during the July 1995 Intensive Observation Period (IOP). A 2D cloud ensemble model (CEM) is used to simulate the macroscopic properties of midlatitude cumulus ensembles. The observed large-scale, horizontal advective tendencies ...

Simulation of Boiling in a Vertical Channel Using Ensemble Average Model

Simulation of turbulence boiling, generation of vapour and predication of its behaviour are still subject to debate in the two-phase flow area and they receive a high level of worldwide attention. In this study, a new arrangement of the three dimensional governing equations for turbulence two-phase flow with heat and mass transfer are derived by using ensemble averaging two-fluid model and ...

Cloud Ensemble Simulation with Data from the Atmospheric Radiation Measurement Intensive Observation Period

The main objective of this study is to use Atmospheric Radiation Measurement (ARM) intensive observation period (IOP) data to refine a cloudiness parameterization, as proposed by Xu and Randall (1996a). The cloudiness parameterization uses the large-scale average condensate (cloud water and cloud ice) mixing ratio as the primary predictor. The large-scale relative humidity and cumulus mass flux...

The Marine Stratus/Stratocumulus Experiment (MASE): Aerosolcloud relationships in marine stratocumulus

[1] The Marine Stratus/Stratocumulus Experiment (MASE) field campaign was undertaken in July 2005 off the coast of Monterey, California to evaluate aerosol-cloud relationships in the climatically important regime of eastern Pacific marine stratocumulus. Aerosol and cloud properties were measured onboard the Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) Twin Otter aircr...

Cirrus Cloud Properties from a Cloud-Resolving Model Simulation Compared to Cloud Radar Observations

Cloud radar data collected at the Atmospheric Radiation Measurement (ARM) Program’s Southern Great Plains site were used to evaluate the properties of cirrus clouds that occurred in a cloud-resolving model (CRM) simulation of the 29-day summer 1997 intensive observation period (IOP). The simulation was ‘‘forced’’ by the large-scale advective temperature and water vapor tendencies, horizontal wi...
