An Investigation of Thunderstorm Potential in Cold Air Cumulonimbi.
Abstract
The purpose of the study is to introduce a method of determining the differenc between cold air cumulonimbi with thunderstorm potential from those with no such potential for development. This problem frequently occurs in winter over northwestern Europe. Several theories on thunderstorm activity and observational evidence are combined in a simplified theory of cloud electrification. This theory is applied in a stability index, similar to the Lifted Index with the exception that parcels are raised to the -20C level. This index is useful in cold air for separating areas of thunderstorms from those in which only cumulonimbus clouds occur. (Author)
