Abstract
It is possible that the technique of wind analysis, developed long ago by Sandstrom and V. Bjerknes, may supplement the standard isobaric and frontal analysis of surface weather maps. A first approximation to a theory concerning the relation between asymptotes in the wind field and frontal zones suggests that the technique might reveal, by simple inspection of the separate frontal and wind analyses, the speed of movement of frontal zones, changes in their intensity and the sign of the vertical motion in their neighborhood.
