A technique to provide vertical wind distribution through the mid-latitude (polar) tropopause in the 300- to 200-mb layer is described. Vertical wind-shear charts computed from the horizontal temperature gradients are used to delinate wind variations with alttiude in the upper troposphere and lower stratosphere.

Examples of vertical wind-shear charts and the suggested operational usages are presented.
