Abstract An important aspect of numerical weather model improvement is the identification of deficient areas of the model, particularly deficiencies that are flow dependent or otherwise vary in time or space. Here the authors introduce the use of self-organizing maps (SOMs) and analysis increments from data assimilation to identify model deficiencies. Systematic increments reveal time- and space-dependent systematic errors, while SOMs provide a method for categorizing forecasts or increment patterns. The SOMs can be either used for direct analysis or used to produce composites of other fields. This study uses the forecasts and increments of 2-m temperature and dry column mass perturbation μ over a 4-week period to demonstrate the potential of this technique. Results demonstrate the potential of this technique for identifying spatially varying systematic model errors.

This study investigated multi-dimensional coordination instability and variability in the transitions between walking and running for a 26 year old female runner using self-organizing maps (SOMs) in three experimental procedures. We found different multi-dimensional coordination patterns for walking and running using the output from SOMs as stride trajectories on U-matrices and attractor diagrams. In transient conditions, the participant showed multi-stability, or instability, in the transition region for decreasing but not for increasing speeds. She also clearly showed increased multi-dimensional coordination variability around the transition region only for decreasing speeds and only in transient conditions. These findings may not be general across runners nor were they conclusive enough to support variability as a facilitator of the change from running to walking. Self-organizing maps provide us with a tool to study multi-dimensional coordination (and coordination variability) and to reduce its complexity to relatively simple map outputs, including basins of attraction and attractor landscapes.
