Synoptic Charts - High pressure ridge
On the MSL synoptic charts years ago they shows a high pressure ridge with a line. I think it was a _._._ type line where as a trough is a ---------type line.
Can anyone verify that BOM have dropped the ridge line markings on the charts these days, and on the legend, only showing the troughs. Have searched throug the whole BOM website and no reference to the change.
