Closer examination of the Amarillo precipitation-PDO reveals that since about 1950, the precipitation curve parallels and lags behind the PDO curve by about 2 years (Fig.
The precipitation curves suggest that the periodicity of Amarillo precipitation operated on a decadal cycle; drought periods in the 1910's, 1930's, 1950's, and 1970's, separated by the wetter decades of the 1920's, 1940's and 1960's.
Here, the intersection of the NbC precipitation curve and the x-axis shows the complete dissolution temperature of NbC.
The value of the indicator equaled time spent inside the AlN phase precipitation curve. This calculation does not depend on assuming a constant cooling rate or temperature field.
