A new method for calculating ALPI : the Aleutian low pressure index / A.M. Surry and J.R. King. : Fs97-6/3135E-PDF

A new method of calculating the area of the Aleutian Low and the Aleutian Low Pressure Index (ALPI) using R software is presented. The ALPI time series is generated using the new method for the full time series, 1900 – 2015. Overall, the new method produces ALPI values that are comparable to previously published values (1900 – 2008), with no difference in periods with positive or negative values. We also introduce a method that estimates the geographic location of the center of the Aleutian Low, and produce estimates of the geographic coordinates for the center of the seasonal Aleutian Low for 1900 – 2015. We observed that the seasonal center appeared more likely to occur to the east of the overall center in years with positive ALPI, and to the west of the overall center in years with negative ALPI.
