This study analyzes the relationships between onset, duration, and maximum extent of Atlantic Cold Tongue (ACT) using ERA5 reanalysis data from European Centre for Medium-Range Weather Forecasts (ECMWF) over period 1979–2019. After calculating start end dates ACT each year, this investigates potential early or late onset that may be linked to duration ACT, which is known influence weather patterns precipitation in surrounding regions West African Monsoon System. Results show 68% years with a...
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...
This study evaluates the performance of two planetary boundary parameterizations in simulating mean climate West Africa using Regional Climate Model version 5 (RegCM5). These are Holtslag scheme and University Washington scheme. Two sets three one-year simulations were carried out at 25 km horizontal resolution with different initial conditions. The first set used (hereafter referred to as Hol), while second (UW) UW). results displayed this an average simulations. During JJAS rainy season,...
