The U.S. Department of Energy's Office of Scientific and Technical Information. The application of statistical turbulence theory to the study of atmospheric clouds has a long history that traces back to the pioneering work of L. F. Richardson in the s. At a phenomenological level, both atmospheric clouds and turbulence are now well understood, but analytic theories with the power to predict as well as explain are still lacking. This deficiency is notable because the.

There is usually a liquid-dominated layer at the top of mid-level stratiform mixed-phase clouds (de Boer et al., b;Riihimaki et al., ) and, when the temperature is low enough, ice. Skip to Main Content. Some convectively forced mixed-phase clouds have cloud bases at T observed in the midlatitudes (i.e., Rangno and Hobbs, ).
Convectively forced mixed-phase clouds can have varying depths, sizes, and modes of by: 1. The results obtained in the study can be instrumental for analysis and interpretation of observed mixed-phase clouds. structure of ice clouds. Through comparison with real observations, e.g.
The Mixed-Phase Arctic Cloud Experiment (M-PACE) took place from Sep. 27 to Oct. 22,during the fall season in the area of the North Slope of Alaska (NSA) ().The primary objective was to collect observations needed to advance understanding of the cloud microphysics, dynamics, radiative properties, and evolution of Arctic MPCs (Verlinde et al., ).Cited by: 2.
‘This book provides a unique comprehensive overview of clouds and their role in the climate system, from the microphysical formation of droplets and ice crystals on aerosol particles, through complex cloud microphysics and cloud dynamics, all the way to cloud radiative effects and.
Observed microphysical changes in Arctic mixed-phase clouds when transitioning from sea ice to open ocean Young, G., Jones, H., Observations of ice multiplication in a weakly convective cell embedded in supercooled mid-level stratus.
Crosier, J., Bower, K. Figure 3(d) reveals that wintertime Arctic mixed-phase clouds can be associated with lower compared to mixed-phase clouds of the SP, which agrees with findings of Shupe and Intrieri.
Simulated and had also the correct order of magnitude (e.g.,). was dominated by except for June and Julywhere was generated as well (Figure 3(f)).
The PDFs of cloud along-track horizontal scales suggest that approximately % of the clouds over East Asia cannot be resolved by climate models with a grid resolution of 1°.
Mean along-track horizontal scales for low-level clouds, mid-level clouds, high-level clouds, and deep clouds are 56 km, 88 km, km, and 99 km, respectively. However, the influence of anthropogenic aerosols on cloud liquid water content and cloud fraction is less clear, and the influence on mixed-phase and ice clouds remains poorly constrained.
Observed changes in surface temperature and radiative fluxes provide additional constraints. Dear all UCP participants, thank you for making this conference very special and enjoyable. The presentations, posters and Cloud Gallery are available here.
Note: We are not calling for papers in any journal. Clouds, through their influence on radiative transfer, help determine Earth's energy budget and its susceptibility to perturbations. Clouds and their associated precipitation. The Walter Scott, Jr.

Apart from low-level clouds, it is noteworthy that vertical resolution plays an important role for mid-level and cirrus clouds.
Although superparameterised simulations improve these cloud characteristics (Wyant et al., b, a), it should be kept in mind that most cirrus clouds are diagnosed, but not explicitly represented, with the. Small-scale structure of thermodynamic phase in Arctic mixed-phase clouds observed by airborne remote sensing during a cold air outbreak and a warm air advection event Elena Ruiz-Donoso, André Ehrlich, Michael Schäfer, Evelyn Jäkel, Vera Schemann, Susanne Crewell, Mario Mech, Birte Solveig Kulla, Leif-Leonard Kliesch, Roland Neuber, and.
The structure of turbulence and mixed-phase cloud microphysics in a highly supercooled altocumulus cloud. Characteristics of mid‐level clouds over West Africa. The daytime cycle in dust aerosol direct radiative effects observed in the central Sahara during the Fennec campaign in June Thus improving mixed-phase cloud parameterizations in climate models is critical to reducing the climate forecast uncertainties.
This study aims at providing improved knowledge of mixed-phase cloud properties from the long-term ACRF observations and improving mixed-phase clouds simulations in the NCAR Community Atmosphere Model version 5 (CAM5).
Kalesse, H., P. Kollias, and W. Szyrmer (), On using the relationship between Doppler velocity and radar reflectivity to identify microphysical processes in midlatitudinal ice clouds, J. Geophys. Res. Abstract. The evaluation of modelling diagnostics with appropriate observations is an important task that establishes the capabilities and reliability of models.
In this study we compare aerosol and cloud properties obtained from three different climate models (ECHAM-HAM, ECHAM-HAM-SALSA, and NorESM) with satellite observations using Moderate Resolution Imaging Spectroradiometer (MODIS).
Optical properties of clouds (including separate fractions and in-cloud water contents) are combined prior to the radiative calculation.
RRTM separates the short-wave spectrum into 14 bands extending from m to m, and models sources of extinction for H2 O, O3. Stevens, B., Acquistapace, C., Hansen, A., Heinze, R., Klinger, C., Klocke, D., Rybka, H., Schubotz, W., Windmiller, J., Adamidis, P., Arka, I., Barlakas, V.
A moist profile above 4 km in Bhubaneswar measured on B showed a dry-air intrusion being eroded by mid-level clouds, whereas the Lucknow profile showed a drier, pre-monsoon profile. Aerosol extinction coefficient and cloud-top height measured using lidar showed an influx of continental aerosol, and intermittent multiple clouds below the.Cloud/radiative feedback Several processes are involved in cloud/radiative feedback.
Clouds can both absorb and reflect solar radiation (which cools the surface) and absorb and einit long-wave radiation (which warms the surface), depending on cloud height, thickness and cloud radiative properties.Supercooled-liquid water is found in mixed-phase clouds.
Mixed-phase clouds have been observed in the temperature range between °C to 0 oC where both ice and supercooled-liquid water co-exists. In fact, a mixed-phase cloud is a three-phase system consisting of water vapour, liquid droplets, and ice particles.
