The fourth version of the International Atmospheric River Conference (IARC 2022) was successfully conducted between 10-14 October 2022. More than 130 presentations were made both in-person and virtually. The in-person component was held in Santiago, Chile, with more than 70 attendees. Another 70 attendees connected on-line. We are very grateful to all participants, who shared their work, established new connections and advanced the AR Science.

All the presentations were recorded and are now available. To view a specific talk or a full session, please sign-in at the Whova platform and browse the agenda. A book-of-abstract is being compiled and will be available by mid-November in this web site.

Once again, thank you for participating in IARC 2022. We look forward to seeing you in the next International Atmospheric River Conference.

Atmospheric rivers (ARs) play a key role in the global 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, triggering floods and landslides, as well as coastal windstorms.

The main objective of the International Atmospheric River Conference 2022 (the fourth IARC) is to advance the state of the AR science (dynamics, impacts, monitoring, forecast & projections) providing a forum to a growing community of researches and practitioners. This event effectively strengthens worldwide, cross-disciplinary collaboration. We also aim at connecting different disciplines, stakeholders and users.

The in-person conference will be held in Santiago, Chile, including plenary talks, poster sessions and breakout room discussions. Plenary sessions will be transmitted on-line, and participants may present remotely if needed.

Main themesPhysics and dynamics aspects of ARs; Hydro-meteorological impacts of ARs Observing, tracking, modeling and forecasting ARs; ARs in past and future climates

Special SessionsSocio-economical impacts of ARs; ARs and polar Meteorology and Climate; Compound events

Abstract Submission Period: May 2nd to June 30th, 2022

Registration: July 1st to October 10th, 2022*

Draft Program: July 31st, 2022

Students are strongly encouraged to attend. The International Atmospheric River Conference 2022 is able to provide a select number of scholarships to cover the registration fee and/or support travel for students and early career (within two years of your PhD) individuals. You must have already submitted your abstract to apply for these scholarships. If you are a student or early career individual presenting on a topic within polar meteorology and climate or you are a student presenting in any other session at IARC click here to apply.
