RADIOACTIVITY AND POTENTIAL VORTICITY

Fig. 11—Distribution of potential vorticity computed from Fig. 8 (see
Fig. 6). Apr. 22, 1963 (00Z). Strontium-90 beta activity at sampling
sites in disintegrations per minute per 1000 scf.
CONCLUSIONS
Project Springfield provided excellent data to support the concept
of tropopause folding and the formation of radioactive layers in the
troposphere. The data also confirm the positive correlation between
potential vorticity and radioactivity. This correlation provides a physi-
cal basis for studying the movement and dispersion of radioactivity and
ozone through the atmosphere. The data also confirm the accuracy of
the isentropic trajectories and the importance of isentropic surfaces in
analyzing atmospheric motions.
