Committee on Mesoscale Processes

Welcome to the webpage of the AMS Committee on Mesoscale Processes. The primary activity of this committee is to organize the Conference on Mesoscale Processes, which takes place in odd years.

The 19th Conference on Mesoscale Processes has been postponed from Summer 2021. It will occur during the 2022 annual meeting in Houston, TX. Additional details can be found at the conference website.

The committee plans on resuming normal conference schedule for the 20th Conference on Mesoscale Processes, joint with Numerical Weather Prediction and Weather and Forecasting, in Summer 2023.

Topics covered at this meeting typically include (but are not limited to):

  • Organized moist convection
  • Gravity waves and turbulence
  • Orographic flows and rainfall
  • Tropical and extratropical cyclones
  • The diurnal cycle
  • Microphysics
  • Aerosol effects
  • Data assimilation and predictability
  • Theoretical and idealized modeling
