Abstract The purpose of this investigation is to identify the dominant mid - tropospheric winter circulation patterns over North America during the period 1949-1974, and to deter¬mine which of the major patterns are responsible for winter precipitation in Wisconsin. Using standardised 700 millibar surface heights as representative of mid-tropospheric circulation, the major circulation anomalies are identified through eigenvector analysis* Examples of observed circulation patterns corresponding to the reproduced anomalies are included, and the temporal variance of the dominant patterns investigated. The most important patterns of total winter precipitation, event frequency , and mean event intensity are extracted from hourly data and are identified using eigenvector analysis. The relationship between the general circulation and winter precipitation in Wisconsin is then identified using step¬wise multiple linear regression analysis.
