El mercado europeo de tomate para consumo en fresco se encuentra actualmente saturado por la oferta de distintas procedencias y la exportación almeriense es una de las responsables de la situación de sobreoferta en determinadas semanas del periodo de invierno. En este trabajo se propone un modelo que recoge la evolución de la exportación semanal de tomate almeriense desde principios de los 80. El análisis efectuado, inscrito en el marco de los modelos estructurales de series temporales, permite mostrar la utilidad de las funciones splines como alternativa parsimoniosa a los modelos convencionales de la estacionalidad, así como su flexibilidad para recoger variaciones estacionales cuyo periodo no es siempre de la misma longitud. Nowadays, the European fresh tomato market is saturated as a consequence of the growth of supplies from different countries, and Almería exports contribute to create oversupply in some weeks during the winter. In this paper a model is proposed in order to analyse the evolution of weekly Almería tomato exports throughout the last two decades. Such an analysis is carried out inside the frame delimited by the structural approach to time series and the usefulness of spline functions as a parsimonious way of modelling seasonal variations in which the period does not remain the same over time is shown.
