Apportionment of Okinawa spring
The aerosol of Okinawa spring is apportioned satisfactorily by two threads that are both short and similar. There are shown in the table below and illustrated on this page.
|Okinawa spring, 16 elements|
|Step 0||Nothing chosen|
|Step 2||Sea and crust chosen, fit 3.00|
|Mallipo thread||Kenting thread|
|Step 3||Mallipo added, fit 0.44||Kenting added, fit 0.54|
|Step 4||Lechang added, fit 0.20||Lechang added, fit 0.21|
Step 0, nothing chosen, shows generally high F-ratios in East Asia, the Atlantic, and parts of the Pacific.
Step 2, after the sea and the best crust (FEC) have been chosen, changes the pattern to one with highest F-ratios in East Asia and Korea. The higest of these is for Mallipo May.
Step 3 adds Mallipo May. The fit improves to a very good 0.44. The fit could even stop here if desired.
Step 4 added the best remaining signature from EAs/JK/WPac, Lechang. This improves the fit to 0.20. the process stops because the apparently high F-ratios for Europe correspond to negative coefficients.
Thus the final solution for the Mallipo thread is Mallipo
May plus Lechang (and sea and crust, of course).
The other thread begins with Kenting, the place with the highest F-ratios in East Asia. The fit improves from 3.00 to 0.54, which is not quite as good as the fit with Mallipo May alone (0.44).
Step 4 in the Kenting thread adds the highest remaining East Asian signature, Lechang. The fit now becomes 0.21, indistinguishable from the fit for the other thread.
Thus the fits Mallipo May/Lechang and Kenting/Lechang are functionally equivalent for Okinawa spring.
