Objective specification of monthly mean surface temperature from mean 700 mb heights in winter ( North America).

Abstract

The simultaneous relation between temperature and circulation during the winter season is studied by correlating anomalies of monthly mean surface temperature at 109 stations in the US from 1948 through 1981 with monthly mean 700 mb height anomalies at a network of 133 grid points in N America and surrounding oceans. By combining dependent and independent samples and by applying the best cut-off criteria plus synoptic experience, final specification equations are computed. These equations explain about 3/4 of the temperature variance by means of from 3 to 9 variables, but with marked regional variation.-from Author
