   Sammanfattning : Hail storms, with hail commonly near 50 mm in diameter that travel with storm wind sabove 25 m/s, cause damages of a large magnitude throughout the globe, with places like USA, Australia and India suffering the greatest. These damages have serious consequences, not least telecommunication products mounted in exposed places. LÄS MER
