Clouds in the Perturbed Climate System

Their Relationship to Energy Balance, Atmospheric Dynamics, and Precipitation


More than half the globe is covered by visible clouds. Clouds control major parts of the Earth's energy balance, influencing both incoming shortwave solar radiation and outgoing longwave thermal radiation. Latent heating and cooling related to cloud processes modify atmospheric circulation, and, by modulating sea surface temperatures, clouds affect the oceanic circulation. Clouds are also an essential component of the global water cycle, on which all terrestrial life depends. Yet clouds constitute the most poorly quantified, least understood, and most puzzling aspect of atmospheric science, and thus the largest source of uncertainty in the prediction of climate change. Because clouds are influenced by climate change, and because complex, unidentified feedback systems are involved, science is faced with many unanswered questions.

This book begins by identifying and describing the baffling nature of clouds. It explores the boundaries of current knowledge on the spatial/temporal variability of clouds and cloud-related aerosols as well as the factors that control clouds, and examines the extent and nature of anthropogenic perturbations. Particular emphasis is given to the connections of clouds to climate through radiation, dynamics, precipitation, and chemistry, and to the difficulties in understanding the obvious but elusive fact that clouds must be affected by climate change. Utilizing the insights of this unique gathering of experts, the book offers recommendations to improve the current state of knowledge and direct future research on clouds in fields ranging from chemistry and theoretical physics to climate modeling and remote satellite sensing.

"...this unique book can be strongly recommended to all scientists interested in the intricate relations between aerosols, clouds, climate and climate modelling.", Peter Warneck, Journal of Atmospheric Chemistry


"This timely and important book contains contributions from several of the world leaders in climate science. It is strongly recommended to scientists who want to understand the scientific issues behind the intricate relation between aerosols, clouds, and climate and who want to contribute to reducing the uncertainty in climate modeling and future climate prediction."
Henning Rodhe, Professor of Chemical Meteorology, Stockholm University

"As the Chief Scientist of the world's largest research program aimed specifically at the climatic aspects of clouds, aerosols, and radiation, I find this unique book, authored by the leading lights in our subject, to be an in-depth review of the latest, hottest discoveries about clouds, including how they are changing now and how they might change in the future. In a style which is thorough yet engaging and accessible, this book reviews, in a single volume, information scattered so widely across the literature that it would take a year or more to find. This book is a godsend to those who would understand the vital role of clouds in the current and future climate."
Warren Wiscombe, Senior Scientist, NASA Goddard Space Flight Center

"Clouds in the Perturbed Climate System, written by leaders in the field, is a major contribution to the state-of-science of the role aerosols play in cloud formation in our changing climate system. This book also provides a cogent direction for future research in the field of aerosol cloud interactions."
Jeffrey T. Kiehl, Senior Scientist, National Center for Atmospheric Research
