A056:
Large-scale Tropospheric Transport and Mixing: Observations, Modeling and Theory





Session ID#: 26444

Session Description:
Large-scale atmospheric transport and mixing play an important role in the global distribution of tropospheric trace gases and aerosols. Examples include isentropic transport of midlatitude pollution into the Arctic, interhemispheric transport and its relation to tropical convection and the Hadley Cell, and stagnation episodes over midlatitudes and their association with the storm tracks. Understanding how various components of the general circulation drive transport is essential for understanding how the concentrations of chemical constituents and water vapor vary in time and space. Furthermore, tropospheric transport circulations are projected to change as greenhouse gases increase in terms of their positions, strength and variability.  Thus, for this session we welcome contributions from observations, modeling and theory on large-scale tropospheric transport and how it may respond to future climate change.
