Desert Expansion and Jet-Stream Shifts
Desert Expansion and Jet-Stream Shifts
The following article appeared in the last days, regarding a new study suggesting global warming has created a deviation in jet-stream patterns, which helps create drought and desert-expansion. From the viewpoint of Reich's orgone-energetic functionalism, which postulates a primary energy in the atmosphere which stands behind both healthy atmospheres (pulsing-rainy) and stagnated ones (deserts-drought), we can view this kind of evidence in a different light.
Certainly, classical science has identified a correlation here, between atmospheric warming and jet stream displacement, but they have the causality 180-degrees off. The deserts are expanding, and forcing the jet to deviate, creating regional warmings which are then averaged out to claim a global warming influence. It is driven by the stagnated dor phenomenon which builds up within desert basins and periodically spills outward to create droughts and heat-waves along the desert periphery. Dust clouds fill such "discharged" hot and dorish air masses, which arrive in wetter regions to create hazy obscured atmospheres, dry conditions and soaring temperatures. The bioenergetic signature behind these phenomenon is missed, as too often the scientific meteorologist works only with weather-maps and images on computer screens, and does not go out into these areas to see what the atmospheres over the deserts, or within the droughty/heat-wave regions actually look like.
I am reminded of my "desert-drought map" produced years ago, (see Pulse of the Planet #2, p.82, 1989) which postulated the formation of droughts from outbreaks of adjacent dor-infested desert regions. This creates not only drought but heat-wave as well, driving up the average global temperature. But in fact it is only a regional warming related to primary desert-expansion. In such cases, the jet stream would always be deflected, and this average deflection appears to be what has been measured.
We are having a snow-blizzard here, as I write! Looking out the window it looks like winter again. What global warming?!

Deserts Expanding With Jet Stream Shift
By ANDREW BRIDGES

WASHINGTON
Deserts in the American Southwest and around the globe are creeping toward heavily populated areas as the jet streams shift, researchers reported Thursday.
The result: Areas already stressed by drought may get even drier.
Satellite measurements made from 1979 to 2005 show that the atmosphere in the subtropical regions both north and south of the equator is heating up. As the atmosphere warms, it bulges out at the altitudes where the northern and southern jet streams slip past like swift and massive rivers of air. That bulging has pushed both jet streams about 70 miles closer to the Earth's poles.
Since the jet streams mark the edge of the tropics, in essence framing the hot zone that hugs the equator, their outward movement has allowed the tropics to grow wider by about 140 miles. That means the relatively drier subtropics move as well, pushing closer to places like Salt Lake City, where Thomas Reichler, co-author of the new study, teaches meteorology.
"One of the immediate consequences one can think of is those deserts and dry areas are moving poleward," said Reichler, of the University of Utah. Details appear in Thursday's Science Express, the online edition of the journal Science.
The movement has allowed the subtropics to edge toward populated areas, including the American Southwest, southern Australia and the Mediterranean basin. In those places, the lack of precipitation already is a worry.
Additional creep could move Africa's Sahara Desert farther north, worsening drought conditions that are already a serious problem on that continent and bringing drier weather to the countries that ring the Mediterranean Sea.
"The Mediterranean is one region that models consistently show drying in the future. That could be very much related to this pattern that we are seeing in the atmosphere," said Isaac Held, a senior research scientist with the National Oceanic and Atmospheric Administration. He was not connected with the research.
A shift in where subtropical dry zones lie could make climate change locally noticeable for more people, said Karen Rosenlof, a NOAA research meteorologist also unconnected to the study.
"It is a plausible thing that could be happening, and the people who are going to see its effects earliest are the ones who live closer to the tropics, like southern Australia," said Rosenlof. Her own work suggests the tropics have actually compressed since 2000, after growing wider over the previous 20 years.
Reichler suspects global warming is the root cause of the shift, but said he can't be certain. Other possibilities include variability and destruction of the ozone layer. However, he and his colleagues have noted similar behavior in climate models that suggest global warming plays a role.
Moving the jet streams farther from the equator could disrupt storm patterns, as well as intensify individual storms on the poleward side of the jet streams, said lead author Qiang Fu, a University of Washington atmospheric scientist.
In Europe, for example, that shift could mean less snow falling on the Alps in winter. That would be bad news for skiers, as well as for farmers and others who rely on rivers fed by snowmelt.
"This definitely favors or enhances the frequency of droughts," Fu said of such a shift.
