A method to determine the amounts of cloud-top radiative and evaporative cooling in a stratocumulus-topped boundary layer
The turbulent processes of a stratocumulus-topped marine boundary layer are not yet fully understood. Among the issues is the relative importance of the effects of cloud-top radiative and evaporative cooling in driving the stratocumulus-topped marine boundary layer turbulence, and in producing cloud break-up. A better way to analyse the relevant observations is needed. Based on the concepts of ...
متن کاملOn the diurnal cycle and susceptibility to aerosol concentration in a stratocumulus-topped mixed layer
Mixed-layer theory is used to study the diurnal cycle of the stratocumulus-topped boundary layer and its susceptibility to perturbations in atmospheric aerosol concentration. Our results show that the diurnal evolution of cloud thickness is sensitive to the entrainment efficiency. For high entrainment efficiencies, the cloud base tends to descend at a faster rate than the cloud top; this differ...
متن کاملThe climatology of planetary boundary layer height in China derived from radiosonde and reanalysis data
The important roles of the planetary boundary layer (PBL) in climate, weather and air quality have long been recognized, but little is known about the PBL climatology in China. Using the fine-resolution sounding observations made across China and reanalysis data, we conducted a comprehensive investigation of the PBL in China from January 2011 to July 2015. The boundary layer height (BLH) is fou...
متن کاملUnderstanding Near-Surface and In-cloud Turbulent Fluxes in the Coastal Stratocumulus-topped Boundary Layers
The objective of this project is to quantify the spatial and temporal variability of the turbulent fluxes in the Monterey Bay area. The analysis from this study provides the surface forcing to our collaborators (AOSN investigators) and enable us to understand these variabilities in relation to the sea states and the stratocumulus-topped marine atmospheric boundary layers (MABL) properties. The ...
متن کاملCoastal Stratocumulus Topped Boundary Layers and the Role of Cloud-top Entrainment
The ability of the U.S. Navy’s Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPSTM) to accurately forecast the height and structure of the Marine Boundary Layer (MBL) in the coastal zone is analyzed and compared to surface and aircraft observations from the Dynamics and Evolution of Coastal Stratus (DECS) field study conducted along the central coast of California from June, 16 to Ju...
