Abstract With their extensive coverage, marine low clouds greatly impact global climate. Presently, are poorly represented in climate models, and the response of to changes atmospheric greenhouse gases aerosols remains major source uncertainty simulations. The eastern North Atlantic (ENA) is a region persistent but diverse subtropical boundary layer clouds, whose albedo precipitation highly susceptible perturbations aerosol properties. In addition, ENA periodically impacted by continental...
Abstract Understanding cloud droplet relative dispersion is critical for mitigating the confounding effect of aerosol‐cloud interactions in simulation global climatic patterns. Diverse effects, meaning that correlation between ( ε ) and fog number concentration N f changes from positive to negative as increases at a fixed liquid water content LWC condition, were found urban observed during winters 2017 2018 Nanjing, China. The dominant microphysical processes driving diverse effects be...
Abstract Joint size and fall velocity distributions of raindrops were measured with a Particle Size Velocity (PARSIVEL) precipitation particle disdrometer in field experiment conducted during July August 2007 at semiarid continental site located Guyuan, Ningxia Province, China (36°N, 106°16′E). Data from both stratiform convective clouds are analyzed. Comparison the observed raindrop shows that increase rain rates arises increases drop concentration diameter while rate is mainly due to...
Abstract Cloud microphysical processes occur at the smallest end of scales among cloud-related and thus must be parameterized not only in large-scale global circulation models (GCMs) but also various higher-resolution limited-area such as cloud-resolving (CRMs) large-eddy simulation (LES) models. Instead giving a comprehensive review existing parameterizations that have been developed over years, this study concentrates purposely on several topics we believe are understudied hold great...
The relationships between fractional entrainment rate and key microphysical quantities (e.g., liquid water content, droplet number concentration, volume mean radius, standard deviation of cloud size distributions) in shallow cumuli are empirically examined using situ aircraft observations from the Routine Atmospheric Radiation Measurement Aerial Facility Clouds with Low Optical Water Depths Radiative Observations (RACORO) field campaign over Southern Great Plains site. results show that...
The simultaneous measurements of vertical velocity and cloud droplet size distributions in cumuli collected during the RACORO field campaign over Atmospheric Radiation Measurement Program's Southern Great Plains site near Lamont, Oklahoma, US, are analyzed to determine effects on number concentration, relative dispersion (the ratio standard deviation mean radius), their relationship. results show that with increasing concentration increases while decreases. data also exhibit a negative...
Abstract To study the spatial inhomogeneity of new particle formation (NPF) in polluted atmosphere China, we conducted simultaneous measurements at an urban site near a petrochemical industrial area and regional background Yangtze River Delta region from September to November 2015. At observed type local NPF event (number events: n = 5), which nucleation was limited small but persisted for 6.8 h on average during daytime. Formation rates 5 nm particles ( J ) were found be correlated...
Abstract This work empirically examines the dependence of entrainment‐mixing mechanisms on averaging scale in cumulus clouds using situ aircraft observations during Routine Atmospheric Radiation Measurement Aerial Facility Clouds with Low Optical Water Depths Radiative Observations (RACORO) field campaign. A new measure homogeneous mixing degree is defined that can encompass all types mechanisms. Analysis homogenous shows that, average, decreases increasing scales, suggesting apparent...

Long-term measurements of help to understand the AIEs and narrow down uncertainties simulation. However, they are still scarce. In this study, more than 4 years comprehensive were utilized at central European research station Melpitz, Germany, gain insight into provide recommendations improving prediction number concentration cloud condensation nuclei (CCN, NCCN).

Abstract Entrainment and detrainment rates ( ε δ ) constitute the most critical free parameters in mass flux schemes commonly employed for cumulus parameterizations. Recently, Zhu et al. (2021) introduced a new approach that utilizes aircraft observations to simultaneously estimate clouds, overcoming limitation of other observation‐based approaches solely yield without offering insights into . This study aims comprehensively evaluate reliability this approach. First, evaluation using an...
Abstract The influence of entrainment, a key process characterized by the entrainment rate in cumulus parameterization, on aerosol‐cloud interactions has been widely recognized. However, despite qualitative links established between and aerosol loading, quantitative relationship based observational evidence remains elusive. This study utilizes aircraft observations clouds during two field campaigns to determine loading. In both campaigns, is negatively correlated with It speculated that...
[1] Turbulent entrainment-mixing mechanisms are investigated by applying a combined approach to the aircraft measurements of three drizzling and two nondrizzling stratocumulus clouds collected over U.S. Department Energy's Atmospheric Radiation Measurement Southern Great Plains site during March 2000 cloud Intensive Observation Period. Microphysical analysis shows that inhomogeneous process occurs much more frequently than homogeneous counterpart, most cases close extreme scenario, having...

Using situ aircraft observations over the U. S. Department Energy's Atmospheric Radiation Measurement Southern Great Plains site during March 2000 Cloud Intensive Observation Period numerical simulations with Explicit Mixing Parcel Model (EMPM),...
Abstract This work examines the relationships of entrainment rate to vertical velocity, buoyancy, and turbulent dissipation by applying stepwise principal component regression observational data from shallow cumulus clouds collected during Routine Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF) Clouds with Low Optical Water Depths (CLOWD) Radiative Observations (RACORO) field campaign over ARM Southern Great Plains (SGP) site near Lamont, Oklahoma. The RACORO simulated using a...
Abstract Cloud droplet spectral relative dispersion is critical to parameterizations of cloud radiative properties, warm‐rain initiation, and aerosol‐cloud interactions in models; however, there no consistent relationship between volume‐mean radius literature, which hinders improving parameterization calls for physical explanation. Here we show, by analyzing aircraft observations cumulus clouds during Routine AAF [Atmospheric Radiation Measurement (ARM) Aerial Facility] Clouds with Low...
Abstract Entrainment‐mixing mechanisms significantly affect cloud droplet number concentration, radius, and spectral shape. Quantitative examination of entrainment‐mixing effects on width is lacking.
