titleTIGGE CDF for Loznica (3-day)

...

The plot below shows the CDF for 14 May 06UTC to 15 May 06UTC for Beograd (left 108 mm observed) and Loznica (right, 110 mm observed).

For this point, the ECMWF forecast was generally worse than for other centres, but might captured the signal one day earlier (8 May). We have to check whether the differences can be due to difference in orography. Optimally, the diagnostics should be done for an area averageTo conclude, the results are quite mixed comparing different centres. The outstanding results are the high precipitation for 3-days from UKMO for Loznica.
