Summary:

Rainfall is often considered as the source of the hydrological cycle. Being able to forecast rainfall accurately has immense practical benefits. In this book, experts from around the world share their knowledge and highlight challenges on rainfall forecasting. Topics discussed include statistical downscaling for short term quantitative precipitation forecasting; empirical approaches in long-term rainfall forecasting; the challenge of warm-season convective precipitation forecasting; the precipitation field in southern Italy; prediction of tropical cyclone rainfall potential in Taiwan mountainous areas, and real time flood control using quantitative precipitation forecast and ensemble approach.
