Three main components of precipitation studies: meteorology, climatology and hydrology, are integrated in this book which provides a broad treatment starting from basic theory. The book deals with precipitation specifically, rather than treating it as part of meteorology, climatology or hydrology. Divided into two main sections, the book first concentrates on the atmospheric processes involved in the production of clouds and on yield precipitation of one form or another. The emphasis in the second part is on our attempts to monitor precipitation at or near the earth's surface and analyse its distribution in time and space. The book will be of use to geographers, hydrologists and environmental scientists who specialize in precipitation studies and to those who require a greater depth of knowledge of the subject.
