Show moreThis document describes the 1976 field program as a coordinated, multiple aircraft storm penetrations, and cloud-base measurements in combination with conventional and Doppler radar observations. Objectives include: identifying the location and micro-physical structure of embryo growth regions (particularly "first echo" regions); determining the trajectories of hailstones and their growth environment; directly evaluating the effects of seeding by using data and radar; and determining the dynamical structure and evolution of the storm.
