Based on daily precipitation from the Global Precipitation Climatology Project (GPCP) data during April–October of 1997–2014 period, extreme rainfall trends and variability over West Africa are characterized using 90th-percentile threshold at each grid point. The contribution amount reaches ~50–90% in northern region while it is ~30–50% south. yearly cumulated indicates significant negative 6°N–12°N; 17°W–10°W 4°N–7°N; 6°E–10°E domains, number days exhibits nonsignificant Africa. empirical...
Tano, R.A.; Aman, A.; Kouadio, K.Y.; Toualy, E.; Ali, K.E., and Assamoi, P., 2016. Assessment of the Ivorian coastal vulnerability. Climate change variability associated factor, such as sea-level rise, could increase exposure Gulf Guinea area to erosion inundation. The processes (relative tidal range, wave height) state factors (geomorphology, slope, coastline rate) have been analyzed evaluate vulnerability index area. This study was divided into three zones based on geomorphology. A (CVI)...
This study assesses the vulnerable state of 566-km Ivorian coastal area using physical (geomorphology, slope, retreat rate, relative sea level rise and wave/Tide energy) socio-economic (coastal population density, harbor, airport, road, land use protected area) factors as indicators. enabled an Integrated Coastal Vulnerability Index to be determined for zone. could defined weighted average indexes based on factors. The revealed that vulnerability western eastern coastlines Cote d'Ivoire are...
This study analyses a 4.5 year (September 2009–March 2014) time-series of remotely-sensed data altimeter significant wave heights to describe the temporal and spatial variability ocean swells along northern coast Gulf Guinea. The NOAA WAVEWATCH III (NWW3) model were used with determine origin that occur Côte d'Ivoire in West Africa. We show Guinea are generated Southern Ocean then propagate from south north South Atlantic Ocean, before turning south-west north-east close coast. finding...
Coastal areas of the Gulf Guinea experience accelerated degradation as a result erosion and flooding associated with intensification extreme marine-meteorological phenomena. The coastal process, especially on sandy or muddy littoral, constitutes one main factors Guinean coast. These risks, which are still poorly studied, could increase over coming decades because climate change human activities that exacerbate them. Data related to ocean forcing (tide, wave, sea level anomaly), hydrologic...
The boreal summer upwelling along the northern coast of Gulf Guinea (GG) is characterized using new in situ sea surface temperature (SST) from onset sensor and satellite TRMM Microwave Imager (TMI) datasets. This study aims to encourage intensive SST measurements at Guinea. It shows good agreement between daily TMI similar coastal date, end durations calculated both Interannual evolution date four stations GG indicates that can be initiated one cape or simultaneously palms three points. also...
Along the littoral shelf of northern coast Gulf Guinea (GG), a minor dry season rainfall regime is concomitantly observed with occurrence major coastal upwelling in July-August-September (JAS). It was then supposed that this drives season. But no previous studies have tried to understand and, study first focusing on question. The investigations undertaken explain Ivorian ERA-Interim data from European Centre for Medium Range Weather Forecasts over 1980-2016 period shown driven by Northward...
The buoyancy flux Bo at the air/sea interface is very useful to understand variability of stratification mixed layer, oceanic mixing, phytoplankton dynamics and then coastal upwelling. atmospheric reanalysis ERA5 ORAP5 data have been used in this study describe sea surface and, its influence on mixing layer consequently upwelling along northern coast Gulf Guinea. negative characterized by a seasonal dominated thermal flux. This has also shown that shallow deeper offshore. value increases...
This study focused on the influence of seasonal coastal upwelling north Gulf Guinea (GG) West Africa Monsoon (WAM) fluxes during 1980-2016 period based ERA-Interim data from European Centre for Medium Range Weather Forecasts (ECMWF). The results show that WAM is responsible most rainfall over but convective precipitation remains major component this rainfall. In area, processes are active April-June when advection high moisture quantity ocean to land established. July-August, dry season...

The rainfall, sea level, ocean swell river data have been used to conduct this work. study showed that is higher September-October. maximum depends annual precipitation accumulated from North South. During rainy period, at GB increases till reach an absolute during minor season October. event October exceptional due...
