Abstract: Within the equatorial zone, Western Equatorial Africa (WEA) has a record low sunshine duration during the June–September dry season due to the persistence of low clouds. This study examines the ability of two reanalysis products (ERA5 and MERRA-2) and eight CMIP6 (…)

Abstract : The tropical cloud forest ecosystem in Western Equatorial Africa (WEA) is known to be sensitive to the presence of an extensive and persistent low-level stratiform cloud deck during the long dry season from June to September (JJAS). Here we present a new climatology of the diurnal (…)

Abstract: This study examines the diurnal to interannual variations of the stratiform cloud cover in May–October (1971–2019) from a 3-hourly station database and from ERA5 reanalyses over western equatorial Africa (WEA). The main diurnal variations of the local-scale fraction and (…)

Article in Open Access at : https://rmets.onlinelibrary.wiley.com/doi/10.1002/qj.4974 Abstract: The intraseasonal variability (ISV) of the stratiform cloud cover over Western Equatorial Africa (WEA) is analysed during the dry season (June–September, JJAS 1971–2019). Each JJAS daily sequence of a regional‐scale index (…)
