The dynamic interplay between the atmosphere and agricultural systems forms the foundation of sustainable food production. As climate variability intensifies and the need for global food security grows, the discipline of Agricultural Meteorology has become more vital than ever. It offers the scientific lens through which we understand how weather influences every crop, every field, and every strategic decision made in agriculture.

The book has been meticulously crafted as an essential resource for students, educators, and practitioners seeking a strong foundation in this discipline. The primary objective of this book is to present a comprehensive, clear, and logically structured exposition of the fundamental principles of agricultural meteorology, while vividly demonstrating their practical applications in crop production and management.

The book begins with foundational concepts in general meteorology and climatology and gradually transitions into the specialized domain of agricultural meteorology. It unravels the intricate relationships between weather parameters and every stage of crop growth—from germination to harvest—highlighting their influence on plant development, productivity, and resilience. Practical applications are emphasized throughout: the use of weather forecasts in farm planning, strategies for managing weather-induced risks such as droughts and floods, and the importance of agrometeorological insights in anticipating and mitigating pest and disease outbreaks.

Contemporary and emerging themes—including crop–weather modeling, remote sensing, and the impacts of climate change on agriculture—are addressed in depth to equip readers with a holistic and forward-looking understanding of the subject. Complex scientific concepts are presented in an accessible and student-friendly manner, supported by examples and quantitative illustrations that encourage applied learning and analytical thinking.

He has organized several national-level trainings, seminars, and symposia in Agrometeorology and allied fields. His academic contributions include over 250 publications, encompassing research papers, popular articles, manuals, teaching aids, and book chapters. In addition, he has authored 30 books and monographs, along with numerous technical and scientific bulletins. He has served as Managing Editor of the Journal of Agrometeorology, Vice President of Association of Agrometeorologists and contributed internationally as Research Collaborator with MARCO (Japan) and SPARC, ETH Zurich (Switzerland).  His expertise has been recognized globally, with appointments to the Expert Team on Agrometeorology (CAgM-WMO, Geneva) from 2018 to 2020, and as a Core Committee Member on Agriculture-Drought at WMO, Geneva for two consecutive terms (2021–24 and 2024–27). He also serves as an External Expert for Research Project Evaluation at the COST Association, European Union, Brussels. A dedicated mentor, Dr. Singh has guided numerous undergraduate, postgraduate, and doctoral students who now serve in prominent positions across India. Widely traveled, he has represented India across the globe in academic and scientific forums. In recognition of his exemplary achievements and enduring impact on agrometeorological science, he was conferred the prestigious title of Fellow of the Association of Agrometeorologists (FAAM) in 2024.

 V Uma Maheswara Rao is a seasoned expert in Agrometeorology, with over four decades of extensive experience in teaching, research, extension, and academic administration. He holds a PhD in the broad field of Agrometeorology and has served in various distinguished roles including Project Coordinator, Principal Scientist, Professor & Head, Agrometeorologist, and Assistant Scientist at CCS Haryana Agricultural University and under the Indian Council of Agricultural Research (ICAR).
