abstract = {[1] Pronounced filamentation of tropospheric and
stratospheric air masses was observed on a flight in the
vicinity of the polar jet stream during the STREAM 1998
campaign in Timmins, Canada. High-spatial resolution ozone
and water vapor measurements showed highly variable
structures for the investigated region. Reconstructing
high-resolution potential vorticity (PV) fields using the
reverse-domain-filling (RDF) technique reproduce the in-situ
ozone measurements qualitatively. Measurements and RDF
results show the intrusion of stratospheric air penetrating
deep into the troposphere. The observed intrusions occur on
smaller horizontal scales than generally assumed for
tropopause folding events. Moreover, fine-scale structures
of tropospheric air masses being lifted up into the
stratosphere could be reconstructed by the RDF technique
using the tropospheric tracer specific humidity in addition
to the more conventional calculations for the stratospheric
tracer PV.},
