Abstract : 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)
