Thanks for the welcome, my interests in the jet stream will compound further as our local Australian media and opposition parties are going mad on the extreme weather events that have encouraged severe bush fire events. The persistant low pressure systems are dragging warm air from the interior associated with strong winds that provide great conditions for wild fires. This will be a weather pattern that will last 30 years, fun times ahead. Down in the Southern Hemisphere we have seen a fairly strong negative AAO with our southern vortex being broken up with Antarctic high pressures and temps. The jet stream has moved away from the south pole and is affecting the mainland of Australia. Down here we are not supposed to be affected by planetary waves so the breakup of the southern vortex is perhaps more of a mystery.

I have also been watching the NH polar vortex and jet streams for the past 4 winters. I am involved in solar research and have an interest in weather effects from a quiet Sun. The jet stream looks to be affected by changes in the ozone quantites in the top of the stratosphere where above 45km the quanity is increasing during this what could be a grand solar minimum. I also think a shrinking thermosphere is somehow related to the changes we are seeing with low pressure systems world wide, the jet stream is meridional no matter what phase the AO is in it seems. The more abundant low pressure systems doing their thing. I am predicting the harshest winter this year to be in Russia and central Europe because of the QBO westerly phase. I have predicted the coming NH winter at the end of July for the last 4 years, the following link shows this coming winter along with links to past predictions. http://www.landscheidt.info/?q=node/311 The Sun and net weather effects are "under new management" during what will be known as the Landscheidt Minimum. The new paradigm should last 30 years and have nothing to do with so called global warming. ps...my research is very different to Landscheidts.
