Title: The Correlation of Mesoscale Humidity Anomalies With Mesoscale Organization of Marine Stratocumulus From Observations Over the ARM Eastern North Atlantic Site

Abstract

Abstract The structure of mesoscale cellular organization in marine cloud‐topped boundary layers is found to be well characterized by using a novel compositing approach based on mesoscale variations in the column water vapor path (WVP). The approach is applied to ground‐based observations from the Atmospheric Radiation Measurement (ARM) Eastern North Atlantic site. Based on a set of satellite and ground‐based observational criteria, 381 hr of closed‐cell and 227 hr of open‐cell cases were selected from late 2015 to early 2018. Strong correlations are found between mesoscale‐filtered cloud properties and WVP for both closed‐cell and open‐cell regimes. In the moist atmospheric columns, the clouds are thicker with higher tops and lower bases, and stronger precipitation compared to that in the dry columns. Overall, cloud properties of open and closed cells covary similarly with mesoscale moisture perturbations, except that the correlation of liquid water path with WVP is much weaker for open cells. The relations of subcloud properties with WVP are also examined. In the moist columns, surface equivalent potential temperature and relative humidity are higher than in the dry columns. A marginally negative correlation between mesoscale‐filtered subcloud turbulence eddy dissipation rate and WVP is found for closed cells. These results aremore »« less

Simulation of Mesoscale Cellular Convection in Marine Stratocumulus: 2. Nondrizzling Conditions

Journal Article Zhou, Xiaoli ; Bretherton, Christopher S. - Journal of Advances in Modeling Earth Systems

Abstract This is the second of two large‐eddy simulation studies on the mechanisms of mesoscale cellular organization in drizzling (open cells) and nondrizzling marine stratocumulus (closed cells). This study uses a hard nudging approach which maintains fixed horizontal‐mean temperature and humidity profiles for a well‐mixed boundary layer with a constant boundary layer depth. For the case studied, closed cells develop and broaden by 32 hr to an aspect ratio of 25. Simulations show that the closed‐cell mesoscale cellular convection is driven by positive feedback from cloud‐induced mesoscale perturbations of longwave radiative cooling.

Surface-based observations of mesoscale cumulus-stratocumulus interaction during ASTEX

Journal Article Miller, M A ; Albrecht, B A - Journal of the Atmospheric Sciences

Data obtained from the island of Santa Maria in the Azores, during the Atlantic Stratocumulus Transition Experiment (ASTEX) are used to describe cloud and boundary-layer structure for a 24-h period on 15 June 1992 over the east-central Atlantic. The evolution of the mesoscale cloud structure during a 24-h period in the vertical column above the surface site was characterized using a 94-GHz radar, a laser ceilometer, 3-h radiosonde ascents, and surface micrometerological instrumentation. Mesoscale circulations and drizzle were found to be key elements of the boundary-layer clouds observed in this region. During the late-night and predawn hours, a single layermore »« less

Influences of drizzle on stratocumulus cloudiness and organization [Influences of drizzle on cloudiness and stratocumulus organization]

Journal Article Zhou, Xiaoli ; Heus, Thijs ; Kollias, Pavlos - Journal of Geophysical Research: Atmospheres

Abstract Large‐eddy simulations are used to study the influence of drizzle on stratocumulus organization, based on measurements made as part of the Second Dynamics and Chemistry of the Marine Stratocumulus field study‐II. Cloud droplet number concentration ( N _c ) is prescribed and considered as the proxy for different aerosol loadings. Our study shows that the amount of cloudiness does not decrease linearly with precipitation rate. An N _c threshold is observed below which the removal of cloud water via precipitation efficiently reduces cloud depth, allowing evaporation to become efficient and quickly remove the remaining thinmore »« less

Wavelet Analysis of Properties of Marine Boundary Layer Mesoscale Cells Observed From AMSR–E

Journal Article Zhou, Xiaoli ; Bretherton, Christopher S. ; Eastman, Ryan ; ... - Journal of Geophysical Research: Atmospheres

Marine boundary layer clouds tend to organize into closed or open mesoscale cellular convection (MCC). Here, two-dimensional wavelet analysis is applied for the first time to passive microwave retrievals of cloud water path (CWP), water vapor path (WVP), and rain rate (RR) from Advanced Microwave Scanning Radiometer for Earth Observing System in 2008 over the Northeast and Southeast Pacific, and the Southeast Atlantic subtropical stratocumulus to cumulus transition regions. The (co-)variability between CWP, WVP, and RR in 160 × 160 km² analysis boxes is partitioned between four mesoscale wavelength octaves (20, 40, 80, and 160 km). The cell scale ismore »« less

Simulation of Mesoscale Cellular Convection in Marine Stratocumulus. Part I: Drizzling Conditions

Journal Article Zhou, Xiaoli ; Ackerman, Andrew S. ; Fridlind, Ann M. ; ... - Journal of the Atmospheric Sciences

This study uses eddy-permitting simulations to investigate the mechanisms that promote mesoscale variability of moisture in drizzling stratocumulus-topped marine boundary layers. Simulations show that precipitation tends to increase horizontal scales. Analysis of terms in the prognostic equation for total water mixing ratio variance indicates that moisture stratification plays a leading role in setting horizontal scales. This result is supported by simulations in which horizontal mean thermodynamic profiles are strongly nudged to their initial well-mixed state, which limits cloud scales. It is found that the spatial variability of subcloud moist cold pools surprisingly tends to respond to, rather than determine, themore »« less
