This book is a detailed and timely documentation on recent climate variability phenomenon and ramifications on river hydrology; particularly Indo-Pacific climate impacts. For students and professionals it will serve as a brief explanation to land-ocean-atmosphere interactions and is an excellent introduction to hydrometeorological study. While it is well known that the Indo-Pacific climate largely influences large-scale phenomenon such as monsoons, it is unclear how such impacts manifest regionally, such as at a river catchment scale. The book will examine the direct impact of the Indian Ocean Dipole (IOD), ENSO and ENSO Modoki on the regional river discharges.
