Cumulative Density Functions (CDF) describes the distribution of the values of a variable (e.g.temperature) as forecast by the ENS ensemble members. The CDF curve shows the proportion (in %) of ENS members...

Spread usually, but not always, increases with forecast range. Spread refers to the uncertainty of the values of a parameter but it does not necessarily refer to the flow patterns...
Interval/period: N/A
The ensemble mean is the mean value derived from all the 50 ensemble members plus the control member. This value attempts to capture the general picture while smoothing out spurious detail...
Interval/period: N/A
The ensemble spread is a measure of the differences between the 50 ensemble members plus the control member and is represented by the standard deviation with respect to the ensemble mean...
