A correlation analysis of a thickness tendency equation including heating and vertical motion terms was carried out. One of the main purposes of the investigation is to provide a firmer foundation for a 1000-500 mb thickness forecast scheme. A large data sample was used and single and multiple linear coefficients were calculated. These were computed for a wintertime situation with separate analyses for Atlantic and Pacific areas. The resulting correlation coefficients for the advection, vertical motion and heating terms gave substance to the hypothesis that the observed change in thickness may be fairly well approximated by the change due to horizontal advection only. The vertical motion term gave a smaller but significant correlation, while heat exchange terms did not correlate significantly.
