Open Discussion: “Astronomy meets Meteorology”
A special session will be dedicated to an open discussion with the participation of a few scientists who leads a few among the most powerful ground-based facilities from which the success of future ground-based astronomy will depend on, responsible for forthcoming facilities, scientists leading operational forecasts systems, research groups developing atmospherical models and data assimilation systems.

- Presentation to the two communities (Astronomers and Meteorologists) of what an Extremely Large Telescope and an Operational Forecast Atmospheric Model consist on (challenges, budget, man power, complexity)
- Present and future for a Flexible-Scheduling system in astronomy
- Infrastructures, technologic options/solutions for an implementation of an efficient monitoring of meteorological conditions at Astronomical Observatory’s summits. Which support from the International Meteorological Centers ? PC Clusters or Supercomputers – which solution for an astronomical observatory ?
- Future of modeling in astronomy strongly depends on many “boundary conditions”. The quality and performances of algorithms, turbulence closure schemes and theory that we can decide to employ have an ultimate limitation: the quality of the initial conditions (i.e. meteorological forecasts) used to predict the optical turbulence. Astronomical Observatories are frequently placed in remote regions in the world where the density of meteorological stations is usually lower than in other more crowded regions (Europe and US). Improvements in the quality of meteorological forecasts in these regions should be mandatory to enhance performances of optical turbulence forecasts but also simply to strongly improved the efficiency of an Astronomical Observatory's scientific outputs. Is there anything that astronomer and meteorologists can do to get mutual advantage?
