Apple Freeze Frost Webinar

Link to recorded video conference and handouts plus Calculating Growing Degree days how-to and excel file.

Spring is here and there is work to do!  We had a great discussion at the apple round table during the Iowa Fruit and Vegetable Growers Association’s Annual conference in January.  One major concern that has always plagued the Iowa Fruit industry is spring frost.  What is it and what can we do about it?  We have asked Ray Wolf from the National Weather Service in the Quad Cities to video conference with us for an hour to define radiation and advective frosts.  Ray will explain how the two types of frost differ and what management tactics are commercially available to prevent injury. 

Ray Wolf is the Science and Operation Officer for the NOAA National Weather Service (NWS) office in Davenport, Iowa.  He is responsible for managing operations, staff training, and local research. Research interests include radar applications in severe storm decision making, applications of weather and climate information for decision support services, and societal impacts across the weather-climate spectrum.

From 1990-94, Ray was a forecaster at the NWS office in Denver, CO where he evaluated new forecast and warning technologies utilizing a prototype AWIPS workstation and NCAR's Mile-hi Doppler radar that formed the basis of the NWS Modernization. Prior to 1990, he served as an agricultural forecaster in the Midsouth, supporting farmers and producers in the region with weather and climate information.  Ray received an M.S. In Agricultural Climate in 1985 and a B.S. In Meteorology in 1982 from Iowa State University.
