ABSTRACT

Verification of 12-h daily precipitation amount forecasts is considered in Armenia making use of ERA-Interim model output data. The performance of ERA-Interim model is evaluated against observations of 30 meteorological stations of Armenia over the period 1996–2010. Daily precipitation amounts possess high spatio-temporal variability in Armenia associated with complex orography. The verification results have shown that the mentioned variability of precipitation amounts is not reproduced appropriately by forecasted data of ERA-Interim model.
