Peter, I am sure it is the latter. The complexity of BOM weather maps has increased exponentially in the 50 years or so that I have been following them. As more data sites and understanding of the data improves, so too will the charts become more complex and accurate. The downside is that there is a need to interpret the subtle changes. Another example of the challenge of changes in technology. I would welcome David Wilson’s or other persons with better knowlege of weather than I have, but for now, that is my opinion.

Subject: [Aus-soaring] Warm Fronts on the BOM Weather Maps Has any noticed that warm fronts are becoming a feature of our weather maps? I can't remember seeing them before, except possibly well south of Tasmania. David Wilson said something recently about our cold fronts being somewhat like the Northern Hemisphere warm fronts that Wallington describes in his book (Meteorology for Glider Pilots). In a similar manner troughs were not seen on our weather maps before about the mid 1990's. Now they are every where. Is it Climate Change or is the BOM learning something? -------------------------------------------------------------------------------- _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring
