RISMechanisms Affecting the Transition from Shallow to Deep Convection over Land: Inferences from Observations of the Diurnal Cycle Collected at the ARM Southern Great Plains Site
Publisher: American Meteorological Society
Abstract: Summertime observations for 11 yr from the Atmospheric Radiation Measurement (ARM) Climate Research Facility Southern Great Plains (SGP) site are used to investigate mechanisms controlling the transition from shallow to ...
Factors Controlling the Vertical Extent of Fair-Weather Shallow Cumulus Clouds over Land: Investigation of Diurnal-Cycle Observations Collected at the ARM Southern Great Plains Site
Publisher: American Meteorological Society
Abstract: ummertime observations for 13 yr at the Atmospheric Radiation Measurement Southern Great Plains site are used to study fair-weather shallow cumuli (ShCu). To roughly separate forced from active ShCu, days are categorized ...
Low-Cloud Fraction, Lower-Tropospheric Stability, and Large-Scale Divergence
Publisher: American Meteorological Society
Abstract: This paper explores the capability of the mixed-layer model (MLM) to represent the observed relationship between low-cloud fraction and lower-tropospheric stability; it also investigates the influence of large-scale ...
CMIP3 Subtropical Stratocumulus Cloud Feedback Interpreted through a Mixed-Layer Model
Publisher: American Meteorological Society
Abstract: arge-scale conditions over subtropical marine stratocumulus areas are extracted from global climate models (GCMs) participating in phase 3 of the Coupled Model Intercomparison Project (CMIP3) and used to drive an atmospheric ...
Observed Boundary Layer Controls on Shallow Cumulus at the ARM Southern Great Plains Site
Publisher: American Meteorological Society
Abstract: AbstractThe boundary layer controls on shallow cumulus (ShCu) convection are examined using a suite of remote and in situ sensors at ARM Southern Great Plains (SGP). A key instrument in the study is a Doppler lidar that ...
The Effect of Land Surface Heterogeneity and Background Wind on Shallow Cumulus Clouds and the Transition to Deeper Convection
Publisher: American Meteorological Society
Abstract: Idealized large-eddy simulations (LESs) with prescribed heterogeneous land surface heat fluxes are performed to study the impact of the heterogeneity length scale and background wind speed on the development of shallow ...
Large-Eddy Simulation of Shallow Cumulus over Land: A Composite Case Based on ARM Long-Term Observations at Its Southern Great Plains Site
Publisher: American Meteorological Society
Abstract: AbstractBased on long-term observations by the Atmospheric Radiation Measurement program at its Southern Great Plains site, a new composite case of continental shallow cumulus (ShCu) convection is constructed for large-eddy ...
A Comparison of MERRA and NARR Reanalyses with the DOE ARM SGP Data
Publisher: American Meteorological Society
Abstract: tmospheric states from the Modern-Era Retrospective analysis for Research and Applications (MERRA) and the North American Regional Reanalysis (NARR) are compared with data from the Atmospheric Radiation Measurement Program ...
On the Structure of the Lower Troposphere in the Summertime Stratocumulus Regime of the Northeast Pacific
Publisher: American Meteorological Society
Abstract: Data collected in situ as part of the second field study of the Dynamics and Chemistry of Marine Stratocumulus field program are used to evaluate the state of the atmosphere in the region of field operations near 30°N, ...
