Book excerpt: The VIN project, a coordinated research effort by the Department of Environmental Sciences of the University of Virginia, the Illinois State Water Survey, and the Cumulus Group of NOAA (NOAA/NHEML and later NOAA/OWRM) was developed to investigate the association between the low-level wind field and convective activity in the midwestern U.S. and to further explore the relationships between surface convergence and rainfall found by Ulanski and Garstang in Florida. A key element of the project was a field program in central Illinois, designed specifically to collect measurements for a study of the role of low-level and surface convergence in the evolution of precipitating convective systems and for seeking methods which might be useful in the very short-range forecasting of convective rainfall. This report provides a description of the field program conducted in central Illinois during the summer of 1979, the equipment deployed, and the data base which was generated. In addition, a daily summary of synoptic-scale and local weather and of availability of special observations is given in the Appendix for each day during the program. (Author).

Download or read book The Relationship Between Low level Convergence and Convective Precipitation in Illinois and South Florida written by Andrew I. Watson and published by . This book was released on 1982 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between total area divergence and convective rainfall was examined using surface data collected during the VIN 1979 field experiment in Illinois. The mesonetwork covered an area of 2800 km 2. Total area divergence, an area-averaged quantity, can also be expressed by the line integral of the normal component of the wind around the network boundary. Total area divergence was statistically related to area rainfall based upon the criterion that a convergence event occurred anytime there was a sustained change in total area divergence of less than -1/40000s s-1 for greater than 10 minutes. The difference between initial convergence and maximum convergence was related to total area precipitation associated with the convergence. During the 33-day study, there were 106 convergence events. Forty-four of the events had rainfall, and the average was 1.53 mm per event. The correlation coefficient was -0.50. Other meteorological factors also have an influence on convergence and the production of precipitation such as middle-level moisture, stability, and low-level wind speed which improve the statistical relationships in many instances. Weighted convergence, a subset of total area divergence was also used to develop regression relationships. When compared with south Florida relationships from an earlier investigation, the Illinois results show that the correlation between convergence and rainfall has dropped a tenth in almost all cases.
