A11P:
Atmospheric Circulations and Their Role in the Hydrological Cycle: Monsoons, Storm Tracks, and the ITCZ I


Session ID#: 10980

Session Description:
The transport of water vapor by atmospheric circulations determines the global spatiotemporal pattern of precipitation. Latent heat release during condensation of water vapor in turn feeds back on the strength of atmospheric circulations. This coupled problem needs to be addressed in order to understand what determines spatial patterns of precipitation, the strength of atmospheric circulations, and how these quantities change with climate change. We invite presentations focusing on the physical mechanisms linking atmospheric circulations and the hydrological cycle, where the phenomena of interest could be (but are not limited to) the Hadley and Walker circulations, monsoons, synoptic or stationary eddies, or the ITCZ.
