It is a biophysical science which focuses on making use of weather information to enhance the quantity and quality of crop production. Various other disciplines contribute to this subject such as soil physics, chemistry, hydrology, phenology and agronomy. Agricultural climatology or agroclimatology is a branch of science which deals with the study of the influence of climate on conditions of agricultural plants and animal husbandry. This book attempts to understand the multiple branches that fall under the discipline of agricultural meteorology and climatology and how such concepts have practical applications. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
