Plots from the Metview exercises

The gallery below shows examples plots from all the practical exercises the participants were able to do with the Metview macros developed by Sandor Kertesz in ECMWF's forecast department.

Most of the plot types can be animated with Metview.

MSLP, Z500 and track of Hurricane Nadine	PV/320K and MSLP	MSLP, 10m wind, Z500 & windspeed, SST	Cross-section through Hurricane Nadine and cut-off low showing PV, theta and wind vectors. Illustrates warm core of Nadine and cold core of cut-off.

HRES (deterministic) forecast


MSLP & T2m, Z200 & windspeed, equiv. potential temp., 850hPa wind & T	Total precipitation	Z500 difference between HRES & analysis

Ensembles


RMSE curves Z500 for ensemble	MSLP ensemble mean and spread compared to analysis	MSLP ensemble spaghetti plot

Ensemble stamp map total precipitation over France	Ensemble difference stamp map of z500	Comparing MSLP of perturbed ensemble member to analysis

Difference maps of two ensemble members to analysis	Cumulative distribution function MSLP for ensemble forecast at Toulouse, France

Principal component analysis and Clusters

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


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.

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.
