Joint Session 27 The Role of Atmospheric Rivers in Weather, Water, and Climate Enterprise

Tuesday, 9 January 2018: 10:30 AM-12:00 PM
Room 1 (ACC) (Austin, Texas)
Hosts: (Joint between the Sixth Symposium on the Weather, Water, and Climate Enterprise; and the 32nd Conference on Hydrology )
Duane E. Waliser, JPL, California Institute of Technology, Pasadena, CA

The intense horizontal transports of water vapor by atmospheric rivers (ARs) are fundamental to the global cycles of energy and water, and also determine regional patterns of weather, water, and climate variability and extremes.  Research into atmospheric rivers now includes field experiments, model simulations and forecasts, diagnostic analyses, and climate-change projections. The science of atmospheric river benefits and impacts has begun to engender new applications in support of operations and decision support for communicating risks for hazards such as flooding and challenges such as water resources management.  This session encourages contributions that span topics from atmospheric river science to AR-related applications, such as the communication of risk and other decision support services.
