The STEPS field program will be conducted in Eastern Colorado and
Western Kansas from 22 May to 16 July 2000. The broad goal of STEPS is
to achieve a better understanding of the interactions between
kinematics, precipitation production, and electrification in severe
thunderstorms on the High Plains. The specific scientific objectives
include:
- To understand the apparent major differences in storm processes that have led supercells to be considered as either low, medium (also referred to as classic) or heavy precipitation (LP, MP, and HP) producers.
- To understand how observed differences in the distribution of precipitation and cloud particles in different types of severe storms cause systematic differences in the way these storms electrify and in the types and rates of intracloud and cloud-to-ground lightning that are produced.
- To verify and/or to improve inferences of precipitation type from polarimetric radar measurements.
