The Mesoscale & Microscale Meteorology Division


Our Mission

Comprised of approximately 70 staff and an ever-revolving group of visiting researchers, MMM seeks to understand and accurately represent mesoscale and microscale atmospheric processes in models of weather and climate. Additionally, MMM's research advances theories of convective systems; the predictability of weather systems including precipitation processes; the development and structure of turbulence; and boundary layer processes. Research studies span a wide range of scales from microphysical processes, to the role of clouds in climate.

The Mesoscale and Microscale Meteorology Division is one of 4 divisions and one institute within the Earth and Sun Systems Laboratory of the National Center for Atmospheric Research. NCAR is managed by the University Corporation for Atmospheric Research (UCAR).
