Implications from the North Dakota Tracer Experiment of 1993 for the Glaciogenic Seeding of Supercooled Convective Clouds to Suppress Hail
AbstractDuring the summer of 1993, a study of thunderstorm and hail development, known as the North Dakota Tracer Experiment (NDTE), was conducted in the Bismarck, North Dakota region. The primary objective of this study was to examine airflow and hydrometeor transport through convective storms. The focus was on the development of flanking line cumulus clouds upwind of a primary thunderstorm cell, and on the airflow through and around these flanking line cumuli. One specific goal of the study was to determine if a mechanism existed for the transport of hail embryos between flanking line cells and the main cell and, if it did, what the nature of this mechanism might be. A second goal was to study the transport of simulated seeding material released according to procedures followed by the North Dakota Atmospheric Resource Board (NDARB) in their successful hail suppression work in western North Dakota.
