.. i was wondering about the astrological signification for this warming up?
Hi Themis. This got me to wondering what the astrological connection between the planets and the ozone it. I naturally assume Neptune's importance because he creates fog and dissolves. Ruling the oceans helps, also since the water mass and weather cycles are part of the ozone cycles. I looked to Uranus for any breakdown, natural or otherwise and to Pluto for destruction and recycling. I first wondered about OOB cycles because this is when they operate above and beyone normal. I looked at the last 100 years. Pluto has been a good boy and even with his oddball orbit, he's remained in bounds. Interesting? During the last century Uranus has only been out of bounds twice. Each period was in and out of bounds for about 4 years, 1903-1907 and 1947-1952. Neptune, the great dissolver has only been out of bounds off and on during a 16 year period from 1937-1953. Notice that it is after the out of bounds periods for the century that the attention to and study of the ozone layer begins.
The best article I found on the cycles and studies of the ozone is here:
http://www.usyd.edu.au/envsci/students/notes/air/notes7-1_06.pdf
In it they point out the natural thin spot over Antartica from Sept-Nov. each year, spring time there. They also point out the changes from the 11 year Sun spot cycle, 4-7 yr El Nino cycle and the 2 yr stratosphere wind change cycle, reversing east to west and back again. But what I found most interesting is this:
"...For instance, mean October ozone at Halley Bay on the Antarctic coast was 117 DU in
1993, down from 321 DU in
1956.
(Notice in the chart below, the declination of Uranus and Pluto are just completing a parallel in 1956. Also notice that Uranus and Neptune are parallel in 1993. None were out of bounds during 1956-1993)
History of Discovery
Ground-based measurements of ozone were first started in 1956, at Halley Bay, Antarctica. Satellite measurements of ozone started in the early 70's, but the first comprehensive worldwide measurements started in 1978...
In 1974, M.J. Molina and F.S... Rowland published a laboratory study demonstrating the ability of CFC's to catalytically breakdown ozone in the presence of high frequency UV light... Further studies estimated that the ozone layer would be depleted by CFC's by about 7% within 60 years and based on such studies the US banned CFC's in aerosol sprays in 1978. Slowly, various nations agreed to ban CFC's in aerosols but industry fought the banning of valuable CFC's in other applications. A large shock was needed to motivate the world to get serious about phasing out CFC's and that shock came in 1985. Published in Nature, May 1985, a field study by Farman, Gardinar and Shanklin summarized data that had been collected by the British Antarctic Survey showing that ozone levels had dropped to 10% below normal January levels for Antarctica. ...In fact, however, NASA had observed such drops throughout the previous decade... But in 1984, at the same time as the British survey, NASA noticed a sudden increase in flagged ozone values from October 1983 onwards and decided that the values must be real and not errors. ...ozone depletion over the
Antarctic leading to the formation of a
“hole” was seen as far back as 1976.
(Uranus and Neptune are again parallel in 1975)
Progression
The Ozone Hole and ozone depletion progressively
got worse until the mid 1990s. Since then, some
aspects have improved while others have levelled off.
For example, the absolute ozone level minima
measured at the South Pole have been increasing
since the mid 1990s, but the overall size of the Hole
has not decreased, although it seems to have
stabilised.
Once again in 1995 Uranus and Neptune, then in 2002 Uranus and Pluto were parallel, corresponding perhaps to the improvement.
Ozone Depletion
Ozone depletion is not just a problem particular to the South Pole. Since 1984, numerous studies have confirmed both the existence of the Antarctic hole, as well as an overall
global decrease in ozone. One major study calculates that the global ozone
has decreased 2.5% from 1969 to 1986
(Uranus-Pluto contraparallel midway through this period) and another 3% drop from 1986 to 1993,
(Uranus comes within orb of being parallel Neptune) above and beyond what natural factors could account for. The springtime loss of stratospheric ozone over Antarctica is the largest depletion. Currently, in non-polar regions, the ozone layer has been depleted up to several percent compared with that of two decades ago.
...the magnitude of ozone depletion varies between the regions of the Earth. For example, there has been little or no ozone depletion in the tropics (about 20 degrees north and south of the equator). The magnitude of the depletion also depends on the season. From 1979 to 1997, the observed losses in the amount of ozone overhead have totalled about 5-6% for northern mid-latitudes in Winter and Spring, about 3% for northern mid-latitudes in Summer and Autumn, and about 5% year round for southern mid-latitudes. Since the
early 1980s, the ozone hole has formed over Antarctica during every Southern Hemisphere Spring (September to November), in which up to 60% of the total ozone is depleted. Since the early
1990s, ozone depletion has also been observed over the Arctic, with the ozone loss from January through late March typically being 20-25% in most of the recent years. All of these decreases are larger than known long-term natural variations."
(Beginning in the early 80s Uranus and Pluto were within a couple degrees applying and then separating parallel, then as they moved out of orb, Pluto moved into to orb of being parallel Uranus. This leads me to widen the orb for parallel a bit.
