Analysis of Significant Weather on Meso-Alpha Scales Using Conventional and Remotely-Sensed Data - Further Studies
Abstract
This report summarizes three M.S. Thesis research. Chapter 2 examines the atmospheric structures accompanying some meso-alpha-scale cloud patterns and the surface weather affiliated with them, via detailed analyses of wind fields involving time-space conversion of hourly profiler-measured horizontal winds and rawinsonde winds and temperatures. Chapter 3 summarizes a study using profiler three-dimensional winds at 5-minute intervals (or less) to examine the structure of meso-beta-scale precipitation bonds. In Chapter 4 winds from 2- and 3- station wind profiler networks are used to examine the circulations associated with atmospheric fronts. A number of analysis techniques were examined for use with wind profiler data. The deployment of a network of wind profilers across the Midwest will allow for real-time analysis improvements using the techniques described above, and these improved diagnoses should lead to improvements in now casting and very-short-term forecasting. Further, the insertion of time-height series of data from the profiler network into mesoscale numerical weather prediction models, via four-dimensional data assimilation, will allow for impressive improvements in mesoscale short-term forecasting.
