Short summary
We develop a new classification method for synoptic circulation patterns. Its unique novelty is the use of the modified structural similarity index metric (SSIM). We demonstrate an exemplary application of the synoptic circulation classes obtained with the new classification method for evaluating historical climate simulations. We introduce a distance metric to measure the match in frequency and duration of synoptic classes between a climate simulation and the reference.
