Table 4.7

Derived forecast

Notes:

  1. Large anomaly index is defined as (number of members whose anomaly is higher than 0.5SD) - (number of members whose anomaly is lower than -0.5SD)}/(number of members) at each grid point.

SD is the 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 Product Definition Template 4.8.
