Forrest,
Townsville now appears to be the target. http://www.aoml.noaa.gov/phod/dataphod1/work/HHP/NEW/2007084spsha.png Mackay has changed its SHA profile dramatically as cyclone 2IP has entered the frame. http://www.solar.ifa.hawaii.edu/Tropical/Gif/swp.latest.gif The SHA maps I am presenting are coarser pixel size but have the advantage of permanence. They are not deleted after 2 days as are the Trinane maps I have been using. As for other low coastal SHA features, they are all associated with some kind of river, port of civil or industrial development. The way Mackay changed so abruptly indicates that these features are likely associated with wastewater streams and are controllable. As coriolis forces restrict cyclone trajectories mostly above the Tropic of Capricorn, only those SHA plumes above TOC will be relevant thermodynamic targets. There is a relevant plume off Weipa that is of interest as well. At this time heat is escaping the tropics as the sun retreats northwards and coastal targets are changing, so we will have to wait and see what final second law of thermodynamics(2LT) outcomes will occur. There is enough heat NE of Qld for those outcomes to be reasonably severe. http://www.aoml.noaa.gov/phod/dataphod1/work/HHP/NEW/2007084spsst.png Posted by KAEP, Tuesday, 27 March 2007 4:08:46 AM

Thanks for the successive SHA map links. I note on the the most recent one, that although the scale is a little larger, the dark blue is seemingly much more 'pixellated' as well as contracted off Mackay, if that is the correct term. Is this a relatively more degraded map than that of 17 March?
What do the three pronounced brown areas on the 17 March map off the east coast represent? There is also one of these at the western edge of the Bight, and another in the SE corner of the Gulf. What process is producing these? Why do areas (as in the case of the SE corner of the Gulf) go from one end of the anomaly scale to the other so apparently quickly, rather than just going to the middle of the range?
I also note that nobody seems to be challenging the science behind the range of assertions you are making. I don't pretend to be able to do this myself, but I believe I know from another area of enquiry what such silence likely means. Please kaep explaining. I think you have a quite wide audience.
