7 Things to Know in Atmospheric Science is a practical and constructive guide to the seven key subdomains in atmospheric science. For those looking to expand their knowledge of atmospheric science or transition from another discipline, the text will leave them with deeper insights and wider perspectives. The opening chapter explains how synoptic-scale weather evolves by maintaining the geostrophic balance. Then the author introduces the radiative transfer process under the gray-atmosphere approximation. Unique characteristics of the thermodynamics are explained by focusing on the concept of entropy. Cloud physics processes of leading clouds into rains are presented as an introduction to the subject. The Monin-Obukhov similarity theory is presented as an entry point for the boundary-layer meteorology. Ozone hole chemistry is introduced as an example of atmospheric chemistry. The last chapter presents an overview of modern forecast methodologies. This concise guide to the primary subdomains of atmospheric science provides an in-depth view of a complex discipline that allows readers to engage with it on a deeper, more meaningful level. - Introductory guided tour of atmospheric science research - Researchers can gain a full glance of atmospheric science in a single book - In-depth discussions of each domain of atmospheric science, which helps the reader more quickly and easily engage with specialized subjects
