 Zusammenfassung: A series of ozone transects measured each year from 1987 to 1990 over
the western Pacific and eastern Indian oceans between mid-November and
mid-December shows a prominent ozone maximum reaching 50-80 ppbv between
5 and 10 km in the 20 degrees S-40 degrees S latitude band. This maximum
contrasts with ozone mixing ratios lower than 20 ppbv measured at the
same altitudes in equatorial regions. Analyses with a global chemical
transport model suggest that these elevated ozone values are part of a
large-scale tropospheric ozone plume extending from Africa to the
western Pacific across the Indian ocean. These plumes occur several
months after the peak in biomass burning influence and during a period
of high lightning activity in the Southern Hemisphere tropical belt. The
composition and geographical extent of these plumes are similar to the
ozone layers previously encountered during the biomass burning season in
this region. Our model results suggest that production of nitrogen
oxides from lightning strokes sustains the NO(x) (= NO + NO(2)) levels
and the ozone photochemical production required in the upper troposphere
to form these persistent elevated ozone layers emanating from biomass
burning regions.
