    v11 v12  
    4444My working hypothesis is that areas of difference will propagate downstream with increasing forecast lead time,
    4545
     46   * For a particular basetime sequence of forecast hours
     47     * At the start of the trial period (20171201T06 - 20180101T06) when the background was similar in both runs the forecast difference would be less. However for basetimes further away from the start basetime there's less memeory - i.e. background diverges between 2 runs and hence analysis difference would be great and hence forecast difference would be greater
     48
    4649   * Simply looking at difference for a particular basetime may not yield anything. Better way to bring out differences is to average all the differences for each forecast range. This is based on my hunch: at 00 forecast hour absence of Macquarie Island obs should produce differences around the Island. This difference will move eastward while being amplified
