  abstract = {{T}hanks to the {GEOSAT} altimeter data set, information on sea level changes during the 1986-87 {E}l {N}ino is presented. {S}pecial emphasis is placed on the warm pool area, with an evaluation, a detailed description and tentative explanation of the observed {S}ea {L}evel {A}nomaly ({SLA}) changes. {N}ear the 165°{E} longitude,the onset of the 1986-87 {E}l {N}ino is characterized by a rapid development of a positive (> 14 cm) equatorial {SLA} in november-december 1986. {T}his feature occurs in response to an eastward wind anomaly appearing between 140°{E}-170°{W} along the equator. {T}he wind induces a downwelling equatorial {K}elvin wave with phase speed of about 2.3 m.s.-1. {T}hereafter, equatorial {SLA} remains quite constant from january to april/may 1987. {I}n june 1987, equatorial {SLA} decreases to a minimum value, just after an abrupt change of the zonal wind stress anomaly, west of 165°{E}. {S}uch anomaly seems to force an upwelling equatorial {K}elvin wave propagating at about 2.3. m.s-1.},
