Notes:

Composite Max. is the difference betweeen the mean of the 10 members with the largest metric value and the mean of the members with the metric value smaller than the mean. Shaded units are standard deviation of the field.
Composite Min. is the difference betweeen the mean of the 10 members with the smallest metric value and the mean of the members with the metric value greater than the mean. Shaded units are standard deviation of the field.
Composite Diff. is the difference betweeen the mean of the 10 members with the largest metric value and the mean of the 10 members with the smallest metric value. Shaded units are standard deviation of the field.
Sensitivity is the change in the forecast metric value per one standard deviation change in the field at that location. Shaded field units are mm per standard deviation of the field.
