I. The mean state of circulation in some of the months can be demonstrated by the mean position of the frontal zone. From the position of the frontal zone we can determine if the zonal or meridional circulation prevails, and in which way it will change during the year
II. The long-range variation of the mean frontal zone in relation to solar activity expressed by Ejgenson s Index of Recurrency of Sunspots A is determined. The effect ascertained is especially significant in January. The results in maps show the deviations of frequencies of the zones from the mean state, partly in the years of minima, partly in the years of maxima of the recurrency of sunspots.
