| MetO

| Fast bias at low wind speed
| Investigate if there is evidence that this is speeding up NWP analyses in
low wind speed areas. If so consider action. ECMWF
have investigated and it looks like there is some
evidence.
| MetO ECMWF
| Yes |
| Ensure consistent display of speed bias density
plots
| Most of the ECMWF plots are produced at the Met
Office to ensure uniformity of format. The one
exception is the density plots, which are still produced
at ECMWF. A change was made with the January 2008 data to
ensure a standard colour range is used for all density plots from
both centres. The standard deviation was modified to
be that of the speed difference rather than vector
difference for the Met Office plots from Sep08,
bringing it in line with the ECMWF plots.
| ECMWF
| Yes (Jan08 / Sep08) |
| Add a new section for investigations
| To provide some one-off or occasional studies.
For example to produce the standard NWP SAF plots, but
additionally separated by height assignment method.

| Action
| Details
| Centre(s)

used to show some unexpected differences due to
inconsistent use of QI pre-filtering.
| MetO ECMWF
| Yes |
| Produce ECMWF vector plots
|
| ECMWF MetO

from the Met Office (e.g. for the unedited data),
others should be produced by both centres.
