Landscapes and Climate: How Orography and Land-Ocean Distributions Shape Past, Present and Future Climate on Continental to Global Scales

Session ID#: 83390

Session Description:
Orography and land-ocean distributions are known to profoundly influence large-scale climate across a wide range of temporal scales. However, many questions remain unsettled or even unexplored regarding the impacts of the size, shape, surface properties and geological evolution of orography and continents on the hydrological cycle, circulation patterns, and climate variability.

In this session, we invite contributions covering conceptual understanding, hierarchical modeling, paleoclimate reconstruction, and observational diagnostics to highlight recent advances in understanding the impacts of landscapes on regional and global climates. Contributions are highly encouraged on, but not limited to: the effects of mountain uplift and changing land-ocean distributions on the evolution of Earth’s climate, including stationary waves and monsoons; impacts of large-scale changes in vegetation or land-use on climate; impacts of tropical islands; climatic controls of mid-to-high latitude large orography and ice sheets; and the role of mountains on remote climate variability and extreme weather events.
