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?

This depiction of an atmospheric river, interacting with West Coast mountains and a midlatitude cyclone over the northeast Pacific on 5 February 2015, provides an example of approximate locations of associated tropical moisture exports and a warm conveyor belt (WCB).
