Abstract
Daily maximum and minimum temperatures since 1897 at three stations in Wisconsin are examined, and the hypothesis is tested that there is no association between interdiurnal or interannual temperature and either the local mean temperature or an estimate of the hemispheric temperature. The hypothesis had be accepted for interannual variability; it had to be rejected for interdiurnal variability. The association between interdiurnal variability and mean temperature is negative for winter and positive for summer, which is due to Wisconsin's location with respect to the general circulation patterns.
