Each year hailstorm damage to human life, property, livestock, and agriculture is appalling in nature. Broadly, there are two problems related with hailstorms i.e. cloud physics problem of the growth of hailstones and the synoptic problem which relates to the thermodynamic investigation of the conditions that produce hailstorms. Thus, present book discusses climatology, physical properties of hail, measurements, prediction, control and damage assessment. Separate chapter discusses the typical features of hailstorm formation. Forecasters in any part of the world could find fair order of similarity in the synoptic models discussed amongst the four regions of India, with their regions, too.
