There has been a long history of unexplained anomalous absorption solar radiation by clouds. Collocated satellite and surface measurements at five geographically diverse locations showed significant clouds, resulting in about 25 watts per square meter more global-mean the cloudy atmosphere than predicted theoretical models. It often suggested that tropospheric aerosols could increase cloud absorption. But these are temporally spatially heterogeneous, whereas observed is remarkably invariant...
Abstract Mixed‐phase stratiform clouds contain numerous liquid, mixed‐phase, and ice clusters, quantifying the cluster scales is potentially helpful to improve parameterizations of microphysics radiation models. However, hydrometeor clusters at different levels are not well understood. In this study, using airborne measurements a large eddy simulation, we show that turbulence plays an important role in controlling with length few hundred meters, while larger have stronger vertical variations...
Abstract The charge structure in thunderstorms may be strongly affected by different secondary ice production (SIP) processes, but has not been well understood. In this study, the impacts of three SIP mechanisms on microphysics and electrification a squall line are investigated using model simulation, including rime‐splintering, ice‐ice collisional breakup, shattering freezing drops. parameterization mechanisms, noninductive an inductive charging implemented spectral bin microphysics....
To investigate the absorption of shortwave radiation by clouds, we have collocated satellite and surface measurements at several locations. Considerable effort has been directed toward understanding minimizing sampling errors caused being instantaneous over a grid that is much larger than field view an upward facing pyranometer. The data indicate clouds absorb considerably more predicted theoretical models. This consistent with finding from both aircraft observed are darker model clouds. In...
Abstract In mixed‐phase cumulus clouds, droplets and ice crystals are inhomogeneously distributed, such spatial inhomogeneity can be enhanced by inhomogeneous entrainment as it strengthen the particle clustering, which may further influence phase partitioning interactions among hydrometeors. However, scale of clustering induced is not well known. Utilizing high‐resolution in‐situ aircraft measurements in this study shows due to entrainment‐mixing, cluster scales decrease approximately 10 m...
Abstract Accurate representation of cloud phase partitioning is critical for understanding the feedback to climate change, but supercooled liquid fraction often underestimated in global models, part due assumption homogeneous distributions hydrometeors mixed‐phase clouds. In this study, we take into account heterogeneous liquid‐ice mixing modeling ice depositional growth using airborne situ measurements. The impact on Wegener‐Bergeron‐Findeisen process parameterized as that mixed with water,...
Abstract One of the major factors controlling phase partitioning in mixed‐phase cloud is entrainment mixing, but it still poorly understood. In this study, liquid‐ice mass across edge shallow to moderately deep cumulus clouds are analyzed using airborne measurements. The results show concentration and water content both liquid ice decrease toward edge. However, fraction remains similar cloud. mechanism responsible for that extreme inhomogeneous entrainment‐mixing dominates. This evident as...
