Principal component analysis and Clusters

After computing the EOFs a clustering can be applied to all of the above ensemble plots.

 
Image Removed

EOF and PCA analyses of ensemble
spread for Z500 using clustering (top graph;
clusters shown as either red or blue dots).

Z500, ensemble mean of cluster 1 and 2
(top left & right respectively), compared
to HRES & analysis bottom.		Stamp difference map of MSLP with
clusters enabled. Maps are ordered
according to which cluster they are in

Stamp map of total precip. with
clustering enable. Maps are ordered
according to their cluster.

 Image Added 
Ensemble spaghetti plot with clusters. Top left and top right
show ensemble members in cluster 1 & 2 respectively.		Z500 RMSE curves with clusters.
Ensemble members in each cluster
are plotted separately.		 .

Probabilities

Two ensemble forecasts datasets were provided for the workshop. The 2012 operational ensemble and a reforecast using the operational ensemble of 2016.

Image AddedProbabilities of total precipitation greater than 20mm
for both ensembles at 3 different forecast times.
