This textbook provides a comprehensive and contemporary treatment of the physical, dynamical, radiative, and chemical processes governing interactions between the Earth’s troposphere and stratosphere. Thoroughly revised and expanded, the second edition integrates atmospheric physics, thermodynamics, radiation, fluid dynamics, chemistry, and transport, with emphasis on the Upper Troposphere–Lower Stratosphere (UTLS), stratosphere–troposphere exchange, atmospheric waves, and tropical–equatorial dynamics. It examines major modes of atmospheric variability, including the Quasi-Biennial Oscillation (QBO), El Niño–Southern Oscillation (ENSO), Madden–Julian Oscillation (MJO), Indian Ocean Dipole (IOD), and stratospheric variability, alongside climate change, climate modelling, and emerging applications of artificial intelligence. The first edition of this book received the prestigious ASLI Choice Award (2008) and was translated into Russian and Chinese.
Designed for graduate students, researchers, and professional atmospheric scientists, the book combines rigorous foundations with clear, accessible explanations. Approximately 200 high-quality illustrations and end-of-chapter problems with solutions support conceptual understanding and practical application. By linking fundamental processes with contemporary research, this second edition provides a valuable foundation and long-term reference for the atmospheric science community.
K. Mohanakumar is the former Dean and Professor of Atmospheric Sciences at Cochin University of Science and Technology (CUSAT), India, with more than 46 years of research experience and 32 years of postgraduate teaching in atmospheric dynamics, stratosphere–troposphere interactions, monsoon meteorology, atmospheric waves, and climate variability. He has published extensively in these fields.
