Over recent decades there have been an extraordinary advances across many earth science disciplines, thanks to better observations and understanding of the earth system. This is nowhere better illustrated than in meteorology, where the skill of the three-day forecast now is similar to the skill of a one-day prediction about twenty years ago. Despite these advances there are continuing requirements for improvements; for example, a one-day forecast still cannot give us good enough quantitative rainfall predictions. While major developments have taken place, there are still many advances which need to be made over the coming decades.
