Gradual patterns that capture the order correlations of the form "The more/less X, then the more/less Y" play an important role in many real world applications. In this paper, we propose an approach for extracting (closed) frequent gradual patterns when the ordering of supporting objects matches the temporal order. This approach allows to reduce the quantity of mined patterns when the objects follow a temporal order relation. The experimental results obtained on the paleoecological data show the efficiency of our approach and the interpretation of those results bring new knowledge to paleoecological experts.
