This book was released on 2012 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation combines aircraft in situ and airborne mm-wave cloud radar measurements to make contributions to one fundamental aspect of the study of cumulus clouds: the effect of turbulent mixing. The objective is to improve the understanding of processes of entrainment and detrainment of cumulus clouds and their impacts on ambient air. The method used is compositing, i.e. the characterization of typical patterns, and their variations, by combining numerous samples, in this case samples of shallow to mediocre cumulus clouds. Clear evidence is produced to prove the existence of horizontal vortex-ring structures commonly observed within the top of cumulus clouds. Significant lateral and vertical entrainment of ambient air into clouds is described. The lateral entrainment occurs through relatively small eddies and the typical lateral mixing length is 10-15% of the cloud diameter, whereas vertical entrainment mainly occurs through a vortex-ring concentration within the upper half of cloud. In the developing stage of cumulus clouds, the cloud-scale vortex-ring circulation at cloud top has a more erosive effect on clouds than laterally-mixing eddies because the former penetrates deeper and thus reduces the buoyancy more effectively than the latter. The detrainment signature of a life cycle of non-precipitating moist convection is described as well. The layer containing orographic cumuli clearly becomes enriched with moist static energy immediately downwind of the cumuli. This enrichment reduces potential instability but increases ambient humidity, which may facilitate successive cumulus growth.

This book was released on 2012-12-06 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of convection in geophysical flows constitute an advanced and rapidly developing area of research that is relevant to problems of the natural environment. During the last decade, significant progress has been achieved in the field as a result of both experimental studies and numerical modelling. This led to the principal revision of the widely held view on buoyancy-driven turbulent flows comprising an organised mean component with superimposed chaotic turbulence. An intermediate type of motion, represented by coherent structures, has been found to play a key role in geophysical boundary layers and in larger scale atmospheric and hydrospheric circulations driven by buoyant forcing. New aspects of the interaction between convective motions and rotation have recently been discovered and investigated. Extensive experimental data have also been collected on the role of convection in cloud dynamics and microphysics. New theoretical concepts and approaches have been outlined regarding scaling and parameterization of physical processes in buoyancy-driven geophysical flows. The book summarizes interdisciplinary studies of buoyancy effects in different media (atmosphere and hydrosphere) over a wide range of scales (small scale phenomena in unstably stratified and convectively mixed layers to deep convection in the atmosphere and ocean), by different research methods (field measurements, laboratory simulations, numerical modelling), and within a variety of application areas (dispersion of pollutants, weather forecasting, hazardous phenomena associated with buoyant forcing).

Available in PDF, EPUB and Kindle. Book excerpt: This study estimates entrainment rate and investigates its relationships with cloud properties in 156 deep convective clouds based on in-situ aircraft observations during the TOGA-COARE (Tropical Ocean Global Atmosphere Coupled Ocean Atmosphere Response Experiment) field campaign over the western Pacific. To the authors' knowledge, this is the first study on the probability density function of entrainment rate, the relationships between entrainment rate and cloud microphysics, and the effects of dry air sources on the calculated entrainment rate in deep convection from an observational perspective. Results show that the probability density function of entrainment rate can be well fitted by lognormal, gamma or Weibull distribution, with coefficients of determination being 0.82, 0.85 and 0.80, respectively. Entrainment tends to reduce temperature, water vapor content and moist static energy in cloud due to evaporative cooling and dilution. Inspection of the relationships between entrainment rate and microphysical properties reveals a negative correlation between volume-mean radius and entrainment rate, suggesting the potential dominance of homogeneous mechanism in the clouds examined. The entrainment rate and environmental water vapor content show similar tendencies of variation with the distance of the assumed environmental air to the cloud edges. Their variation tendencies are non-monotonic due to the relatively short distance between adjacent clouds.
