  abstract = {{A}n ocean general circulation model is forced with {NCEP} reanalysis over the 1948-1999 period. {T}he simulated dynamic height and sea level are compared respectively to the dynamic height computed from hydrological data and to the sea level measured by tide gauges in the tropical {P}acific. {T}he model is shown to capture important features of the temporal structure of variability in the tide gauge data over the last several decades. {H}owever, the comparison reveals a largely artificial trend in the simulation, which consists of a decreasing dynamic height and sea level in the southwest and northwest of the tropical {P}acific. {M}odel sensitivity experiments show this trend is controlled by the {NCEP} surface wind stresses and more precisely by a weakening in the trade winds and a trend in the off-equatorial wind curl, with this trend existing mainly before the mid 1970s. {F}or studies of decadal variability, the simple removal of a linear trend is an inadequate way to solve the problem, due to the inhomogeneities in the data used in reanalysis products and the non-linearity of models.
