Résumé :
Analogues of circulation have found many innovative uses in the past few years, including climate reconstructions, attribution of event and data assimilation. After presenting the gist of the methodology of analogues and its link with recurrences in dynamical systems, I will show how this methodology can be used to design stochastic weather generators with coherent spatial features. I will also argue that such tools can also be used to perform ensemble predictions of climate variables such as temperature. I will give several examples of such applications.
