RESEARCH ON CHARACTERISTICS AND EFFECTS OF SEVERE STORMS.
Abstract
In the first part of this report an examination is made of the large-scale conditions under which severe local storms develop. Detailed case-studies have been made in respect of six situations, five of which are described here. In two of these, over Western Europe, severe hailstorms occurred, one with tornadoes, and in another storms failed to develop. In the other two situations, tornadic hailstorms developed over and near the state of Oklahoma. It is concluded that the occurrence of the most intense storms depends upon a favourable combination of geographical and large-scale atmospheric flow features. In the several case studies the technique of analysis used isentropic charts showing the flow relative to a large-scale motion system, assumed to be in a steady state. In the second part of the report this technique is discussed and shown to have some advantages over conventional methods, sufficient to justify its further examination. (Author)
