Clouds and humidity remain sources of significant uncertainty, but improvements in simulations of these have been made. Analysis of, and confidence in, extreme events simulated within climate models is emerging, particularly for storm tracks and storm frequency. Performance in simulating ENSO and NAO has improved.
