In order to examine the effectiveness of the NSMC scheme, a comparison was arranged under the cooperation frame between EUMETSAT and CMA (China Meteorological Administration). Two periods of data from Meteosat-5 including IR and WV channels were processed and compared by both the EUMETSAT and NSMC schemes. The comparison periods were one week long each, and in January and July respectively. The...

Meteorological extremes have large impacts on society. The fact that approximately 40% of the Netherlands is below sea level makes this country especially vulnerable to flooding, both from the sea and from rivers. This has resulted in extensive research on the statistics of extremes. However, applications to meteorological and hydrological situations are always hampered by the brevity of the av...

introduction precipitation is one of the most important meteorological variables in comparison with other climatic parameters. it varies extremely over time and space. the occurrence of this climate phenomenon requires specific circumstances in environment. its accurate measurement is important to a wide range of decision makers including hydrologists, agriculturalists, industrialists and etc. ...

A hydrological ensemble prediction system, integrating a water balance model with ensemble precipitation forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) Ensemble Prediction System (EPS), is evaluated for two Belgian catchments using verification methods borrowed from meteorology. The skill of the probability forecast that the streamflow exceeds a given level is mea...

ENVISAT fast delivery RA-2 and ASAR wind and wave products are routinely received, monitored and validated at ECMWF. RA-2 wind speed product is of good quality. Although Ku-band significant wave height (SWH) product is slightly high, it is of high quality. The redundant side B of RA-2 produced SWH product of even better quality. The S-band wave height product is generally of good quality. The i...

Numerical experiments with the global model of the European Centre for Medium-Range Weather Forecasts (ECMWF) were devoted to the sensitivity of the modelled evaporation and precipitation to the vegetation Leaf Area Index (LAI). The temporally static LAI-distribution was replaced with a seasonally varying LAI, derived from Normalized Difference Vegetation Index (NDVI) archives. The seasonality ...
