Atmospheric processes specific to mountainous regions heavily affect the exchange of momentum, heat and mass between the Earth’s surface and the atmosphere.

TEAMx (Multi-scale transport and exchange processes in the atmosphere over mountains – programme and experiment) is an international research programme that aims at improving our understanding of these processes. Long-term objectives of TEAMx are optimizing numerical models and observational systems for application over mountainous terrain, improving weather forecasts and climate change scenarios over mountains, and characterizing more accurately the global cycles of water, energy and trace gases. The Programme Coordination Office of TEAMx has been established at ACINN in August 2018, and is funded by a joint investment (TEAMx-Seed) of the participating institutions.

Vertical mixing of low-level air masses is often more effective in mountainous areas than over lowlands. On this autumn day, lower moisture and more effective vertical mixing kept the sky free of clouds over the Alps, creating a striking contrast with the low stratus covering the surrounding plains.
