                   SCIENTIST PREDICTS DEEPER OZONE HOLE OVER SOUTH POLE 
IN 1996
NOAA 96-62

 SCIENTIST PREDICTS DEEPER OZONE HOLE OVER SOUTH POLE IN 1996

Ozone depletion over the South Pole this year could be worse than in 1995 
by as
much as 10 percent, according to an analysis of ozone trends from balloon
measurements taken at the South Pole for the past ten years.

David J. Hofmann, director of the National Oceanic and Atmospheric
 Administration's Climate Monitoring and Diagnostics Laboratory (CMDL) in
Boulder, Colo., wrote in the Sept. 12 issue of Nature that the variation 
in
ozone depletion at the South Pole from one year to the next may be 
related to
changing stratospheric wind patterns and the transport of air from the 
tropics
to the poles.

"We are seeing increased ozone depletion at the South Pole, which we 
believe
was caused by a change of wind in the tropics from westerly to easterly,"
Hoffman said. "In particular, ozone loss rates have been greater in years 
where
the winds at very high altitudes have been easterly for several months 
early in
the calendar year preceding the ozone hole period." This may cause more
ozone-depleting halogens (chlorine-and bromine-containing molecules) to 
be
transported from the tropics to the poles prior to formation of the 
winter
vortex, causing greater ozone depletion the following spring. If this
hypothesis is correct, Hofmann said, ozone depletion in September 1996 
should
again be high.

"The fact that ozone depletion over the South Pole may be worse in 1996 
than in
1995 doesn't necessarily mean that overall ozone depletion is increasing. 
We're
just starting to understand the interannual variabilities better," 
Hofmann
said. Understanding the cause of this variability in ozone loss rate will 
be
important for the detection of the expected recovery of the ozone hole 
early in
the next century.

According to Hofmann, ozone depletion in the Antarctic has been 
especially
severe since 1992, caused in part by aerosols from the Mt. Pinatubo 
volcanic
eruption, which enhance the ozone-destroying ability of the man-made 
halogens.
The effects from that eruption have largely subsided so that the 1995 
ozone
hole, although one of the longer lasting events in recent years, was not 
as
deep as in 1993 or 1994. The ozone hole in 1995 was measured at 129 
Dobson
units during the late September-early October period, a slight 
improvement over
the 119 Dobson units measured in 1994, and the 109 Dobson units measured 
in
1993. A Dobson unit is a measurement of the thickness of the ozone in a 
column
of air from the ground to the top of the atmosphere.

However, Hofmann says, this is not a sign of recovery from ozone 
depletion in
Antarctica. The ozone hole will continue to fluctuate for some years to 
come in
spite of recent research that shows that chlorine and other 
ozone-depleting
chemicals are starting to decline in the lower atmosphere. Based on
measurements and models, Hofmann believes the level of ozone-depleting
chemicals in the Antarctic stratosphere should peak in about the year 
2000 and
then begin a slow decrease. " Full recovery of the ozone hole is not 
expected
until about 2050. But the more we understand the fluctuation and 
variabilities,
the better we can monitor the recovery," Hofmann added.

Graduate Research Assistantships
Agricultural & Resource Economics Program
West Virginia University

1997-98 Academic Year

The Program in Agricultural & Resource Economics (ARE) at West Virginia
University anticipates several GRA openings beginning in Fall 1997.  We
solicit applications at both the M.S. and Ph.D. levels.  Current GRA rates
are $9,396 (M.S.) and $11,040 (Ph.D.) for 12 months of employment, and
include a tuition waiver.  To qualify for the position, the applicant must
be a graduate student accepted into the ARE program.  GRA appointments are
based solely on academic merit.

The ARE program has around 35 M.S. and Ph.D. students, approximately half
of whom are funded by the program.  Our areas of concentration at the Ph.D.
level include Natural Resource and Environmental Economics, Commodity
Market Analysis, Modeling, and Forecasting, and Rural, Regional, and
International Development.

Kedves Kornyeszek!

Szeretnenk az MME reszerol nyitni az interneten a madaraszok fele. Eloszor 
valami madarasz listat inditanank, de remelhetoleg lesz majd Web 
Vendegoldalunk is. 

Ezert akit erdekelne a reszvetel a 
	 
listan, az irjon egy drotlevelet a cimemre.

Szinten szeretnem kerni, ha valaki ismer nehany MME tagok, akinek van 
drotlevelcime (email), irja meg nekem, legyen szives.
