The objectives of this investigation were to determine the feasibility of deriving vertical velocity patterns, the magnitudes of those patterns, and the three-dimensional wind field in severe convective storms. A technique called Tracking Radar Echoes by Correlation (TREC), also called the NEXRAD Transverse Wind algorithm, and data from a single radar were used to determine the internal storm motions. The radar data were composed of Nature Severe Storms Laboratory (NSSL) Doppler data collected on 19 June 1980. TREC uses correlation analysis to determine motion within and around a given storm. TREC was used to determine the u and v wind components. These components were gridded using a standard objective analysis technique. It has been shown that in weak reflectivity regions random pattern matching can occur, therefore in areas of reflectivity less than 10 dBZ TREC-derived data were viewed with caution. Important results of this study are: 1) there was good agreement in both areal extent and magnitude between the TREC-derived vertical velocities and the dual-Doppler velocities; 2) for time increments of 5 min or less between radar volume scans, the horizontal wind field derived by TREC agreed with the dual-Doppler wind field during the multicell and transition phases of the storm; 3) the effects of the generator level motions on the TREC derived wind field were evident only in the supercell phase and; 4) vertical cross sections indicated regions of updrafts, storm-relative inflows especially in regions of updrafts, updrafts extending through a bounded weak echo region, and an apparent gust front.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

A model is presented which describes the three-dimensional location of the updraft in a convective storm as a function of the wind velocity in the low-level inflow to the storm and the storm's motion. This updraft-plane model was used to interpret doppler velocities in RHI scans. The updraft-plane model led to the following hypothesis on the role of vertical shear in the environmental wind in controlling the life cycle of convective storms. If there is an alignment between the horizontal velocity of the middle level air in which the downdraft originates and the orientation and motion of the updraft plane, then the downdraft air, as it sinks through the storm toward the ground, will continually find itself underneath the updraft such that precipitation evaporation and precipitation loading many maintain and strengthen the downdraft. Conversely, if an alignment is not present, then the downdraft may not be maintained and the convective storm may be of the short-lived type.
