Abstract
AbstractHigh altitude ER‐2 aircraft observations in both hemispheres of the lower‐stratospheric polar night jet stream reveal generalized scale invariance. The scaling exponent has systematic correlation with wind shear and temperature gradient showing across‐jet persistence, along‐jet anti‐persistence, and an overall average value ≈5/9. The analysis provides a natural connection between generalized scale invariance and traditional large‐scale dynamical meteorology. For one mission in the southern hemisphere composite variograms could be constructed for nitrous oxide and ozone, from which it was deduced that the former is a true passive scalar in the lower stratosphere, while sources and sinks are operative for the latter.
