| Climate is an important factor in choosing a site for vineyard development. To guide in site selection, maps of several important agroclimatological factors were created based on 50 years of weather data. Daily weather data were collected from the National Oceanic and Atmospheric Administration's Summary of the Day series (NOAA, 1952-2001) from 83 sites across the state of Michigan. Continuous spatial estimates of the variables were interpolated using the spline method, which assumes a minimum curvature between nearby points.
Please, note that most of the weather stations in the analysis are not located in sites considered suitable for a vineyard and that the micro- and mesoclimate of a specific vineyard site can be important factors in its success or failure. There may be suitable sites in areas generally noted as unfavorable; for these sites, local topographic factors are even more critical. These maps are for general planning purposes and should not be interpreted as a guarantee of suitability. |
