The Science of Mesoscale and Microscale Meteorology
We are at an exciting time in the science of mesoscale and microscale meteorology. Societal use of, and demand for, mesoscale and microscale atmospheric predictions is growing rapidly, and expanding into areas such as air quality and homeland security. Major progress has also occurred during the past decade in observing capacity at these scales, in the ability of computers to handle complex models at very fine grid scales over large domains, and in the theoretical understanding of related processes. These have enabled more accurate specification of mesoscale and microscale atmospheric, biological and chemical processes in models of the weather and climate. The Mesoscale and Microscale Meteorology (MMM) Division of NCAR leads research in these areas. Our emphasis is on science that is likely to benefit society through improved understanding of atmospheric processes and advances in the science of prediction.
