  abstract = {{T}he main objectives of this study are to assess the regional distribution of sea level in terms of trend and interannual varibility and to analyze the impacts of climate variability modes such as {E}l {N}iño-



{S}outhern {O}scillation ({ENSO}) events, {T}ropical {A}tlantic {C}limate {M}odes of {V}ariability ({TACMV}), {N}orth {A}tlantic {O}scillation ({NAO}) on interannual variability and trend of sea level near the {W}est {A}fricans



coasts. {I}ndices associated with these phenomena are from the {N}ational {O}ceanic and {A}tmosphere {A}dministration ({NOAA}), the {G}lobal {M}ean {S}ea {L}evel ({GMSL}) time series provided by {AVISO} ({A}rchiving



{V}alidation and {I}nterpretation {S}atellite {O}ceanographic {C}enter) and the {R}egional {M}ean {S}ea {L}evel ({RMSL}) gridded data by {CMEMS} ({C}opernicus {M}arine {E}nvironment {M}onitoring {S}ervice). {T}he results show that



the mean regional trend of sea level is similar to the global one but the time evolution at interannual and decadal scales does not follow the pattern of global sea level. {O}ur analysis suggests an influence of



{ENSO} events in the {A}tlantic coast of {W}est {A}frica. {I}n particular, we observed negative {RMSL} anomalies during the two strongest {E}l {N}iño events (1997-1998 and 2015) and a strong positive {RMSL} anomaly



during the {L}a {N}iña event of 2011 (the strongest over the last two decades). {T}he analysis also reveals an influence of {TACMV} and {NAO} on the interannual sea level variability, essentially through regional {S}ea



{S}urface {T}emperature ({SST}) changes. {T}he study shows that a time series of at least 10 years is required to estimate the trend in sea level rise in {W}est {A}frica. {S}ub-decadal trends, primarily reflect natural



climate modes, rather than variations in climate change. {T}his study also shows that the distribution of sea level rise in the {W}est {A}frican region is heterogeneous with higher values near the coast of {W}est



{A}frica and near the equator.},
