Abstract: Using METEOSAT data in the ISCCP B2 format, we study the mean radiation fields and their fluctuations during Northern Hemisphere summer (June, July, August) of 1983, 1984 and 1985, for regions of 5°?5° located from 50°N ...

Abstract: Some aspects of the interannual and the diurnal variations of the convection over the tropical Africa and the Atlantic Ocean are derived using Meteosat data. The study is based on four summer months (June, July, August and ...

Abstract: Using Meteosat data and European Centre for Medium-range Weather Forecast (ECMWF) analyses, we examine easterly waves and their relation with the cloudiness over West Africa and the tropical Atlantic Ocean for three summers ...

Abstract: sing ERA-Interim global atmospheric reanalysis, an original tracking approach is developed to follow tropical low pressure systems from the early tropical depression (TD) stage up to possible intensification into developed ...

Abstract: Spectral analysis of the outgoing longwave radiation (OLR) time series over equatorial Africa reveals large oscillations of the convection with periods of between 3 and 6 days. In March and April, when the intertropical ...

Abstract: During periods of light surface wind, a warm stable layer forms at the ocean surface with a maximum sea surface temperature (SST) in the early afternoon. The diurnal SST amplitude (DSA) associated with these diurnal warm ...

Abstract: This paper presents a method, the local mode analysis (LMA), that makes it possible to extract the most persistent oscillations present in the time evolution of an atmospheric field. This method is particularly suitable ...

Abstract: For the determination of the earth radiation budget (ERB) from space, the reflected solar flux and the emitted longwave (LW: 4?100 ?m) fluxes are estimated using radiance measurements made in shortwave (SW: 0.2?4.5 ?m) and ...
