This book was released on 1994 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are using a hierarchy of numerical models of cirrus and stratus clouds and radiative transfer to improve the reliability of general circulation models. Our detailed cloud microphysical model includes all of the physical processes believed to control the lifecycle of liquid and ice clouds in the troposphere. In our one-dimensional cirrus studies, we find that the ice crystal number and size in cirrus clouds are not very sensitive to the number of condensation nuclei which are present. We have compared our three-dimensional meoscale simulations of cirrus clouds with radar, lidar satellite and other observations of water vapor and cloud fields and find that the model accurately predicts the characteristics of a cirrus cloud system. The model results reproduce several features detected by remote sensing (lidar and radar) measurements, including the appearance of the high cirrus cloud at about 15 UTC and the thickening of the cloud at 20 UTC. We have developed a new parameterizations for production of ice crystals based on the detailed one-dimensional cloud model, and are presently testing the parameterization in three-dimensional simulations of the FIRE-II November 26 case study. We have analyzed NWS radiosonde humidity data from FIRE and ARM and found errors, biases, and uncertainties in the conversion of the sensed resistance to humidity.

Book excerpt: We have used a hierarchy of numerical models for cirrus and stratus clouds and for radiative transfer to improve the reliability of general circulation models. Our detailed cloud microphysical model includes all of the physical processes believed to control the lifecycles of liquid and ice clouds in the troposphere. We have worked on specific GCM parameterizations for the radiative properties of cirrus clouds, making use of a mesocale model as the test-bed for the parameterizations. We have also modeled cirrus cloud properties with a detailed cloud physics model to better understand how the radiatively important properties of cirrus are controlled by their environment. We have used another cloud microphysics model to investigate of the interactions between aerosols and clouds. This work is some of the first to follow the details of interactions between aerosols and cloud droplets and has shown some unexpected relations between clouds and aerosols. We have also used line-by- line radiative transfer results verified with ARM data, to derive a GCMS.

This book was released on 1996 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conducted modeling work in radiative transfer and cloud microphysics. Our work in radiative transfer included performance tests to other high accuracy methods and to measurements under cloudy, partial cloudy and cloud-free conditions. Our modeling efforts have been aimed to (1) develop an accurate and rapid radiative transfer model; (2) develop three-dimensional radiative transfer models; and (3) develop microphysics resolving cloud and aerosol models. We applied our models to investigate solar clear-sky model biases, investigate aerosol direct effects, investigate aerosol indirect effects, investigate microphysical properties of cirrus, investigate microphysical properties of stratus, investigate relationships between cloud properties, and investigate the effects of cloud structure.

Book Synopsis General Circulation Model Development by : David A. Randall
Download or read book General Circulation Model Development written by David A. Randall and published by Elsevier. This book was released on 2000-07-19 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: General Circulation Models (GCMs) are rapidly assuming widespread use as powerful tools for predicting global events on time scales of months to decades, such as the onset of EL Nino, monsoons, soil moisture saturation indices, global warming estimates, and even snowfall predictions. While GCMs have been praised for helping to foretell the current El Nino and its impact on droughts in Indonesia, its full power is only now being recognized by international scientists and governments who seek to link GCMs to help them estimate fish harvests, risk of floods, landslides, and even forest fires.Scientists in oceanography, hydrology, meteorology, and climatology and civil, ocean, and geological engineers perceive a need for a reference on GCM design. In this compilation of information by an internationally recognized group of experts, Professor Randall brings together the knowledge base of the forerunners in theoretical and applied frontiers of GCM development. General Circulation Model Development focuses on the past, present, and future design of numerical methods for general circulation modeling, as well as the physical parameterizations required for their proper implementation. Additional chapters on climate simulation and other applications provide illustrative examples of state-of-the-art GCM design.Key Features* Foreword by Norman Phillips* Authoritative overviews of current issues and ideas on global circulation modeling by leading experts* Retrospective and forward-looking chapters by Akio Arakawa of UCLA* Historical perspectives on the early years of general circulation modeling* Indispensable reference for researchers and graduate students

Download or read book Parameterization of Clouds and Radiation in Climate Models written by and published by . This book was released on 1995 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clouds are a very important, yet poorly modeled element in the climate system. There are many potential cloud feedbacks, including those related to cloud cover, height, water content, phase change, and droplet concentration and size distribution. As a prerequisite to studying the cloud feedback issue, this research reports on the simulation and validation of cloud radiative forcing under present climate conditions using the ECHAM general circulation model and ERBE top-of-atmosphere radiative fluxes.

Download or read book Introduction to Three-Dimensional Climate Modeling written by Warren M. Washington and published by University Science Books. This book was released on 2005-06-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warren M. Washington is consultant and advisor to a number of government officials and committees on climate-system modelling. Now along with Claire Parkinson (NASA) he gives the reader insight into the complex field of climate modelling. Updated and revised from the first edition, this book is a welcome reference on climate modeling; an area that is becoming more and more sought after in light of environmental changes. Suitable for those wanting an in-road into understanding climate modeling but also an excellent companion for those with some prior knowledge of modeling meteorological systems.

Available in PDF, EPUB and Kindle. Book excerpt: This report contains papers from the International Workshop on Cloud-Radiation Interactions and Their Parameterization in Climate Models met on 18--20 October 1993 in Camp Springs, Maryland, USA. It was organized by the Joint Working Group on Clouds and Radiation of the International Association of Meteorology and Atmospheric Sciences. Recommendations were grouped into three broad areas: (1) general circulation models (GCMs), (2) satellite studies, and (3) process studies. Each of the panels developed recommendations on the. themes of the workshop. Explicitly or implicitly, each panel independently recommended observations of basic cloud microphysical properties (water content, phase, size) on the scales resolved by GCMs. Such observations are necessary to validate cloud parameterizations in GCMs, to use satellite data to infer radiative forcing in the atmosphere and at the earth's surface, and to refine the process models which are used to develop advanced cloud parameterizations.
