Notes:

( 1) Large anomaly index is defined as {number of members whose anomaly is higher than 0.5xSD) - (number of members whose anomaly is lower than -0.5xSD)} / {number of members} at each grid point, where SD is defined as observed climatological standard deviation.

( 2) It should be noted that the reference for "minimum of all ensemble members" and "maximum of all ensemble members" is the set of ensemble members and not a time interval and should not be confused with the maximum and minimum described by PDT 4.8
