Alfred Preis, the Honolulu architect commissioned to design the memorial, was the witness to another dark segment
of the war, having spent three months in the Sand Island Detainment Camp in Hawaii, due to his Austrian origin.
One contained the great oval BA plus a smaller anticyclonic white oval (AWO); another was the 'STB Remnant', a pale blue cyclonic circulation; and the third was a new dark segment
of STB, which passed the GRS in late 2009 (Figures 1&3).
More conventional tenderizing processes, such as aging and chemical treatment, digest dark segments
known as Z lines until they disappear.
