Book Description
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.

Book Description
The procedures and results of a study undertaken to evaluate and assess the impacts of three new parameterization schemes for the GL global spectral model as a 3-4 day range forecast model are described. The tree parameterization schemes are one each for the boundary-layer physics, moist convection and heating due to solar and terrestrial radiations. These schemes are incorporated either singly or jointly into a rhomboidal-30, 12-layer global spectral model for four-day simulations using FGGE III- a data as input. Evaluation and assessment are made on the basis of two kinds of global statistics: mean and root-mean-square errors, and on their magnitudes and distributions. The statistics are generated for both the primary, that is, prognostic, variables, and supplementary variables such as zonal-mean and zonal-eddies energy densities. The new moist convection scheme has been found to increase convective activity significantly and maintain it throughout the four-day period. It also warms and dries the middle troposphere, but produces rainfall far in excess of the climatology. The radiation parameterization has been found to cool the atmosphere and reduce its specific humidity. It counterbalances enhanced heating and moistening brought about by the new boundary-layer and moist convection schemes and eliminates the systematic warming of the old model.

Book Description
General circulation model (GCM) experiments in the late 1970's indicated that the climate is sensitive to variations in evaporation at the land surface. Thus, in the context of climate modeling, it became important to develop techniques which would realistically estimate the evaporation flux on land. Land Surface Evaporation: Measurement and Parameterization discusses strategies for the use of experimental data in developing and testing parameterization schemes of the evaporation flux in GCM's. The book reviews state-of-the-art techniques, such as remote sensing, which measure evaporation fluxes over continental surfaces. It evaluates their relevance with respect to the various spatial and temporal scales of interest. This book will provide researchers in climatology, meteorology, hydrology and water management, and remote sensing with a thorough overview of current research in land surface evaporation. It will also give young scientists insight into surface processes.

Book Description
In different areas of the world, much of the damage due to wind is caused by non-synoptic, local wind storm events, such as tornadoes and downbursts. In North America the damage due to these winds is more than 65% of total wind damage, and there are no guidelines or code implementations to deal with such catastrophic events. As we enter the third decade of the twenty-first century, current research is in its first phase of addressing these types of events, from their characterization, simulation, and loading, to collapse-mode effects on buildings and structures, as well as socioeconomic implications. The need is clear to better understand non-synoptic local winds; properly simulate them; assess the difference in loading between these events and synoptic large-scale winds that have been part of the wind engineering practice for more than five decades; determine their statistics and associated risks; and apply this through guidelines, codes, risk mitigation, and adaptation responses to socioeconomic impact. The Oxford Handbook of Non-Synoptic Wind Storms, led by Dr. Horia Hangan and Dr. Ahsan Kareem, features nearly 30 chapters, contributed by an international panel of leading scientists, scholars, and engineers, that address these issues and stimulate thought, research, and responses to non-synoptic wind storm hazards in North America and worldwide. Together, these articles provide clear definitions of the problems to be tackled, offer a strategic framework for forward-looking research, identify the best-suited tools and methodologies to address the problems at hand, and suggest ways to maximize collaborative planning between the disciplines that will tackle these challenges.

Book Description
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.
