This application retrieves the analogues for a selected period of interest (on the order of year, month or day) from a pre-calculated file obtainable from the <a target="_blank" href="https://a2c2.lsce.ipsl.fr/index.php/deliverables/99-continuous-time-analogues">A2C2 website</a>. Analogue counts are binned according to decade, correlation and Euclidean distance. All charts are interactive and linked together so that a selection made in one chart will automatically update all the other charts.

<p><b>Methods:</b>
<p>
We assume that a trajectory of a dynamical system (or an ensemble of trajectories) is observed during a reference period R, and that this trajectory is a good proxy for the underlying attractor. For a distinct target time interval T, we determine, for each t in T, the states of the reference trajectory in R that are closest to the state reached at target time t in T. The closest states found during the reference R are called the analogues of the target T. There are several ways of obtaining closest analogues: by minimizing a distance or maximizing a correlation. The analogue determination hence strongly depends on the criterion to be optimized and there is no objective reason to prefer one method over another [Toth, 1991a], although the results can be different.
<br><br> Here, we use the standard Euclidean distance and linear correlation that are adapted to mean variations. We select the first 20 "best" analogues.
<p>See the <a target="_blank" href="https://a2c2.lsce.ipsl.fr/index.php/structure/97-wp1">A2C2 website</a> for more information.
