Abstract

Estimates of the number of degrees of freedom (dof) of the 700 hPa Northrn Hemisphere extratropical wintertime daily and time average circulation patterns are presented using two statistical methods. In the first method, it is assumed that the distribution of the mean square distances between the circulation patterns and the climate mean follows a χ2 distribution. The other, newly developed hyperspheres method compares the local density properties in the empirical data to density in independently and identically distributed (iid) normal distributions with different number of dof. The advantages of the hyperspheres method as compared to GPM are: 1) no systematic negative bias is present in the dof estimates; 2) the edge effect is eliminated; 3) no scaling is necessary. -from Author
