Abstract: A frontal development observed during the CASP (Canadian Atlantic Storm Project) project is used to investigate the dependence of the spinup time of the divergent circulation on (i) the initial humidity held, (ii) the ...

Abstract: The purpose of this note is to ?validate? the upper tropospheric humidity (UTH) operationally extracted from the 6.3 ?m channel data of METEOSAT. The validation is carded out by comparing the satellite data with observed ...

Abstract: A retrieval method is described for estimating a mean column value of the upper tropospheric relative humidity (UTH) from radiance measurements in the 6.3 ?m channel of the geostationary satellite METEOSAT. The physical ...

Abstract: Diurnal variations of cold cloudiness during a 2-year period (October 1985?September 1987) over the tropical arm covered by Meteosat (from 23°N to 23°S and from 60°E to 60°W) are studied using a simple precipitation index ...

Abstract: Rainfall is estimated in Burkina Faso for a full year using the ESOC precipitation index (EPI), a statistical cloud indexing method based on satellite data from METEOSAT. The EPI is converted into rainfall with the linear ...

Abstract: A validation of the ESOC (European Space 0Perations Centre) Precipitation Index (EPI) is carried out by comparing satellite data with observed rainfall in five African countries to determine the ability of estimating ...

Abstract: The usefulness of numerical weather prediction models in very short-range forecasting is limited by the spinup problem, resulting in an underestimation of both the divergent wind component and the precipitation. To alleviate ...
