WEATHER AND FORECASTING

NWS SOUTHERN REGION SPECIAL ISSUE

September 1997

The following papers which will comprise a special issue of the AMS journal Weather and Forecasting (September 1997) were authored by NWS Southern Region forecasters and faculty or students at universities working in association with NWS offices. While the papers hardly encompass the full range of meteorological and hydrologic problems faced by forecasters in the region, they do illustrate many of the important problems, and they reflect the extent of collaborative activities that are under way in the region.
