H33J:
Advances in Understanding Land-Atmosphere Interactions II


Session ID#: 10573

Session Description:
Land-atmosphere interactions are a key component of the global climate system. Water, energy and carbon transfer between the land surface and planetary boundary layer (PBL) have important impacts on weather and climate variability, predictability, and extremes such as drought. This session focuses on land-atmosphere interactions and characterization of water, energy and carbon cycle fluxes, and subsequent feedbacks and coupling between the surface and PBL. In particular, the impacts of soil moisture and evapotranspiration on PBL, cloud and precipitation development remain a challenge to quantify across a range of scales. We invite observation, satellite and model-based studies of land-atmosphere interactions, particularly at the process-level, and their applications in weather and climate modeling and predictability.
