Our study is concerned with the winter climatology over the Northern Hemisphere for the years 1980 to 1986. / The local E-P flux divergence is divided into barotropic and baroclinic components. The 300 mb level is chosen to represent the upper troposphere. The three dominant convergence centres of the baroclinic component are found on the east coast of Asia, near the eastern Pacific and on the east coast of North America. In most areas the barotropic component of the eddy forcing accelerates the mean flow. Near the dateline the barotropic and baroclinic components of the eddy forcing tend to enhance each other, while on the east coast of North American the barotropic and baroclinic components partially cancel each other. / The three-dimensional structure of some general circulation statistics are discussed, and the results are compared with those of earlier studies. / The possible link between the interannual variation of the seasonal mean flow and the transient eddies forcing is discussed. The results show that no obvious correlation exists in our data set, so that no firm conclusions can be reached.
