Hi All,
Odd happenings in the last week. Snow in February?? If this is Adelaide's hottest month, then by the time we get to our coldest, there will be glaciers sliding down out of the Adelaide Hills.
Reflecting back 30 years or so, Adelaide would get the weather from Perth. If it was 40� in Perth on a Wednesday, then you got organized for a good weekend. The weather cycled through in a regular way. It used to peeve me off because the experts always disappeared on XC in the Blanik, Ka6 and Boomerang and I missed out because I was at the bottom of the heap, experience-wise. We had some good retrieves at times though. We drove all over the place. Those were the days our club experts were doing 500K flights in the Blanik and Ka6.
Then something changed.
I recall stopping to get fuel on the way home from a vintage regatta in Vic. in January 1986 and chewing the fat with the guy in the petrol station about the weather patterns and commenting to him that we didn't get Perth's weather any more, but rather it came from the SW. So at least by then, I had noticed the difference.
Some 20 years later, that hasn't changed. Now the soaring season seems to be dominated by southerly influences with the great weather only on rare days when some other weather pushes in from the north or NE.
So, is this change only a local influence along the southern-Aussie coast or is it now a factor around the entire latitude?
Of course, there is the supposition that the increased heat load on the planet due to human influence is driving a greater transfer of heat from equator to pole which has turn affected the surface patterns by shifting the belts of highs and lows.
And wind. It seems windier than it used to be. Even winter, with, possibly less rain than usual, but so windy.
Makes you want to move to Queensland.
