Date: Thursday, September 20, 2018
Time: 1:00 PM Eastern, Noon Central, 11:00 AM Mountain, 10:00 AM Pacific

”This webinar will provide an overview of where these particles are most prevalent geographically. He will then discuss the basic physical properties of graupel (small hail) and hail, including their mass and sizes. Next will discuss field programs that have been mounted to characterize hail properties, from in-situ aircraft measurements and at the ground. This will lead into a discussion of how hail forms and attempts in the past to reduce hailfall. Also discussed will be how damage from hail has been tested in the laboratory and at the ground. Finally, Andy will conclude by discussing how fast these particles fall and with what energy they impact the ground (kinetic energy).
