The Representation of Cumulus Convection in Numerical Models
This book presents descriptions of numerical models for testing cumulus in cloud fields. It is divided into six parts. Part I provides an overview of the problem, including descriptions of cumulus clouds and the effects of ensembles of cumulus clouds on mass, momentum, and vorticity distributions. A review of closure assumptions is also provided. A review of "classical" convection schemes in widespread use is provided in Part II. The special problems associated with the representation of convection in mesoscale models are discussed in Part III, along with descriptions of some of the commonly used mesoscale schemes. Part IV covers some of the problems associated with the representation of convection in climate models, while the parameterization of slantwise convection is the subject of Part V.

An up-to-date summary of our understanding of the dynamics and thermodynamics of moist atmospheric convection, with a strong focus on recent developments in the field. The book also reviews ways in which moist convection may be parameterised in large-scale numerical models - a field in which there is still some controversy - and discusses the implications of convection for large-scale flow. Audience: The book is aimed at the graduate level and research meteorologists as well as scientists in other disciplines who need to know more about moist convection and its representation in numerical models.
Atmospheric Convection
This graduate-level meteorology text and reference provides a scientifically rigorous description of the many types of convective circulations in the Earth's atmosphere. These range from small-scale, convectively driven turbulences in the boundary layer to precipitating systems covering many thousands of square kilometers. The text introduces the principal techniques used in understanding and predicting convective motion: theory, field experiment, and numerical modelling. Part I explores dry convection, including turbulent plumes and thermals from isolated buoyancy sources, Raleigh-Benard convection, and turbulent convection in the planetary boundary layer. Emphasis is placed on applying theoretical understanding and lessons from experiments. Part II offers a complete treatment of the thermodynamics of moist and cloudy air, including fundamental laws, conserved quantities, graphical techniques, and stability. Part III explores the characteristics of individual convective clouds, thunderstorms, squall lines, mesoscale convective systems, and slantwise convection. Part IV studies the ensemble effects of convective clouds, including stratocumulus at trade cumulus boundary layers and the representation of convective clouds in numerical models. Each chapter is followed by a set of exercises.
