2nd ENA Workshop/ Summer Course on Earth-system processes in the Atlantic

Taking the opportunity of the “Aerosol and Cloud experiments in the Eastern North Atlantic (ACE_ENA)” campaign, which is bringing to the Azores a group of scientists to study processes in the maritime atmosphere, the University of the Azores (through IITAA at the Faculty of Agrarian and Environmental Sciences), the University of Lisbon (through Institute Dom Luiz at the Faculty of Sciences), the Portuguese Institute for Sea and Atmosphere (IPMA) and the ACE_ENA team offer a 1 week workshop/summer_course on earth-system processes.

The impact of mountain waves in the atmosphere at local to global scale

Miguel Teixeira
University of Reading

Despite their relatively small scales, mountain waves have important impacts on atmospheric dynamics and physics. These impacts can be local, such as the generation of clear-air turbulence (CAT) by wave breaking, downslope windstorms and the formation of rotors in the lee of mountains or hills; or global, such as the deceleration of the mid-latitude circulation, the modulation of temperatures in polar regions, or ozone transport and depletion.
