Atmospheric rivers (ARs) play a key role in the water cycle as the primary mechanism conveying water vapor through mid-latitude regions. The precipitation that ARs deliver in many parts of the world, especially through orographic precipitation processes, is important for water resources; but it also regularly is a hazard, with floods resulting. The aims of the 2016 International Atmospheric Rivers Conference are
  • to discuss and identify differing regional perspectives and conditions from around the world,
  • to evaluate the current state and applications of the science of the mid-latitude atmospheric water cycle, with particular emphasis on atmospheric rivers and associated or parallel processes (e.g., tropical moisture exports),
  • to assess current forecasting capabilities and developing applications, and
  • to plan for future scientific and practical challenges.

The conference aims to bring together experts from academia and applications to form a real community of interests. Questions on the table include: What meteorological conditions constitute ARs and what do not? How can ARs (and related processes) best be identified and categorized? What are the most promising new research directions for putting AR science into its proper meteorological/climatological context and improving its applicability?

  • Synopsis:
    The 2016 International Atmospheric Rivers Conference will convene at 8am on Monday 8 August 2016 in the beautiful Robert Paine Scripps Forum at the Scripps Institution of Oceanography in La Jolla, California. Four full days of presentations will cover global regional perspectives on atmospheric river science including associated and parallel processes. A poster session will be held late Tuesday afternoon and will be followed by a buffet dinner on Tuesday evening (lasting until approximately 8pm). Other conference days are expected to end at approximately 5pm.
  • Provided:
    The registration fee will include lunch, a morning snack and an afternoon snack.
