Alpine Summer School - Course XXIII
Land-atmosphere interactions: coupling between the energy, water and carbon cycles
Valsavarenche, Valle d'Aosta, Italy
21 June - 2 July, 2015
The land surface and the overlying atmosphere are tightly coupled systems. These feedbacks are regulated through the interface, the planetary boundary layer in which intense turbulence occurs. Land-atmosphere interactions are important sources of seasonal climate predictability in several parts of the world. Soil moisture and vegetation are key parameters influencing land-atmosphere interactions in the climate system by modifying the surface energy, moisture and carbon fluxes, and boundary conditions for the boundary layer. Because soil moisture, vegetation, turbulence (boundary layer and moist convection) organize on many different temporal and spatial scales, the study of land-atmosphere interactions has been notoriously difficult. The study of land-atmosphere interactions encompass a wide range of disciplines, which will be discussed during the summer school from soil science, surface hydrology, hydrometeorology, plant physiology, turbulence, convection and atmosphere circulation. As such, there is no single type of land-atmosphere interactions but a wide variety of cases embedded within the larger-scale general circulation.
There have been considerable developments in recent years on the subject so that an up-to-date summer school presenting a quantitative approach outlining physical principles, and the mathematical basis of land-atmosphere interactions is required. A book, following up on this summer school and using the lecture materials, will be published by Wiley in 2016.
The courses will cover surface energy, carbon and water balances, soil-plant-atmosphere continuum and plant physiology (motion through the soil, roots, xylem and stomata), surface and boundary layer turbulence, feedback analysis, heterogeneity, shallow and deep convection, extremes, annual and cold season coupling between radiation-turbulence and precipitation, metrics in land-stmohspere interactions, modeling, and remote sensing observations.

14th International Swiss Climate Summer School 2015: Extreme Events and Climate
23–28 August 2015
The Swiss Climate Research, the network of leading Swiss institutions in climate research and education, invites young scientists to join high-profile climate researchers on the occasion of the 14th International Swiss Climate Summer School 2015, whose topic is “Extreme Events and Climate.”
Weather and extreme climate events can result in large disasters. A changing climate can lead to changes in the frequency, intensity, spatial extent, duration, and timing of these events. Understanding the processes underlying the formation of extreme events and improving the predictability of extreme events is a major scientific challenge and of crucial importance for the society. The Summer School will address the following topics:
- Mechanisms and processes responsible for the occurrence of extreme events
- Observational evidence for changes in extreme events
- Uncertainties in seasonal to interannual predictions and long-term projections of extreme events
- Technical, economical, and societal challenges related to extreme events
The Summer School is open to young researchers (PhD students and post docs) worldwide from all fields of climate research. Participation is highly competitive and will be limited to a maximum of 70. Further information about the Summer School and the application procedure can be found at the website.
