Hydrometeorology is an interdisciplinary branch of meteorology and hydrology. It studies the transfer of water and energy between the land surface and the lower atmosphere. An important aspect of hydrometeorology is the prediction and mitigation of the effects of high precipitation events. Nowcasting, numerical weather prediction and statistical techniques are the three primary ways to model meteorological phenomena in weather forecasting. Nowcasting predicts events a few hours out. It utilizes observations and live radar data to combine them with numerical weather prediction models. Numerical weather prediction is the primary technique used to forecast weather. It uses mathematical models to account for the atmosphere, ocean, and many other variables for producing forecasts. Statistical techniques use regressions and other statistical methods to create long-term projections. This book provides comprehensive insights into the field of hydrometeorology. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. This book is appropriate for students seeking detailed information in this area as well as for experts.
