JM01 - Adapting in the Anthropocene (IAMAS, IAHS, IACS)


Convener: Keith Alverson (USA/Japan, IAMAS)

Co-Conveners: Gia Destouni (Sweden, IAHS), Michael Wolovick (USA, IACS)



The detection and attribution of significant human impact on the global environment has been robustly shown across a number of Earth system components. In this context, the concept of planetary boundaries and tipping points has received substantial visibility.  Well known examples include greenhouse gas and aerosol levels in the atmosphere, ice sheet collapse and sea level rise, sea ice loss, plastic and acidification in the ocean, shifts in freshwater availability and quality, and biodiversity loss, nutrient and toxic chemical loading in terrestrial, freshwater and coastal ecosystems. This symposium will highlight examples of where we are experiencing the kind of dominant human impacts on the global environment that define the Anthropocene, with a focus on actions that can be taken to reverse the anthropogenic forcings, reduce their adverse impacts on natural and social systems and provide sustainable services, including food and water security and safety, for a growing and increasingly affluent global human population.

JM04 - Hydrometeorologic and Coastal Extremes in Current and Future Climates (IAMAS, IAHS)


Convener: Laxmi Sushama (Canada, IAMAS)

Co-Conveners: Marie Ekstrom (UK, IAMAS), Richard Grotjahn (USA, IAMAS), Brian Golding (UK, IAMAS), Abhishekh Srivastava (USA, IAMAS), Hubert Savanije (Netherlands, IAHS), Jai Vaze (Australia, IAHS)



Extreme hydrometeorologic and coastal events can have devastating impacts on society and cause millions of dollars in damages. Science and engineering is continuously evolving to predict, model and manage these events to reduce their harmful effects. These extremes include localized flooding caused by short duration heavy rainfall to large scale flooding caused by heavy snowmelt combined with ice-jam and rainfall, and coastal flooding due to storm surge. Extreme events are often complex in terms of causal mechanisms and therefore require investigation from a multi-dimensional perspective. Successful management of extreme events demand timely actions on disaster preparedness, early warning, crisis management, response, recovery and clean-up. Advances in understanding these extremes from a multi-dimensional viewpoint, and modeling from both physical and statistical viewpoints, will continue to evolve as new tools and approaches develop and become available.


This symposium covers hydrometeorologic and coastal extremes in terms of their causal mechanisms, modelling and forecasting, and the adaptation-mitigation-sustainability-resilience nexus. Contributions are invited in the following and related areas:

  • Advances in modelling observed precipitation extremes, floods, droughts, wildland fires, and storm surges;
  • Future evolution, causal mechanisms and forecasting and management of hydrometeorologic and coastal extremes;
  • Hydrometeorologic extremes in relation to developing resilient and sustainable infrastructure.
  • Examples that link physical and socio-economic components of risk exposure and vulnerability.

Abstracts on topics primarily on meteorological extremes modeling, mechanisms, and forecasting are encouraged for submission to the symposium on High-impact Weather and Climate Extremes (M12).



JM05 - Ocean-atmosphere Mechanisms of Variability, Change and Predictability (IAMAS, IAPSO)


Convener: Tim Woolings (UK, IAMAS)

Co-Conveners: Hisashi Nakamura (Japan, IAMAS), Iracema Cavalcanti (Brazil, IAMAS), Toshio Yamagata (Japan, IAPSO)



This symposium welcomes contributions of theoretical, modelling and observational work related to ocean-atmosphere variability and change. Interaction between the ocean and atmosphere plays an important role in many aspects of climate variability, predominantly from seasonal timescales upwards. The associated teleconnections cover the globe and can also interact with other systems such as the land and cryosphere. The long timescales inherent in such coupled variability proves an invaluable source of skill for near-term climate predictions in particular, but the longer term forced climate change signal is also significantly affected by ocean-atmosphere coupling.


Specific topics covered by the symposium include but are not limited to: Tropical coupled variability and teleconnections; mechanisms of mid-latitude air-sea interaction; the role of ocean frontal zones and eddies in the coupled system; representation of air-sea interaction and teleconnections in climate models; role of ocean variability in near-term climate predictability; and ocean-atmosphere coupling under anthropogenic climate change.

JM06 - Recent Advances in Regional Climate Modelling (IAMAS, IAHS, IACS)


Convener: Anne Frigon (Canada, IAMAS)

Co-Conveners: Andrew Orr (UK, IAMAS), Martin Leduc (Canada, IAMAS), René Laprise (Canada, IAMAS), François Brissette (Canada, IAHS), Ross Brown (Canada, IACS)



This symposium addresses regional climate modelling, looking into recent developments and analyses for both validation and climate-change purposes, based on single model to large ensembles of simulations. We are also interested in analyses that go beyond the typical surface meteorological variables, looking into cryospheric and hydrological fields. Contributions are welcome in the following areas, but not limited to:

  • Validation of models through comparison with observations, using various approaches to diagnose the behavior of the model at different spatial and time scales, as well as looking into feedback mechanisms.
  • Analysis of multi-model ensembles (such as CORDEX) for climate-change studies.
  • Analysis of single model large ensembles.
  • Added value of high-resolution simulations, reaching convection-permitting models.
  • Analyses of large-scale patterns and their links to local-scale impacts.

JM07 - Artificial Intelligence and Big data in Weather and Climate Science (IAMAS, IAHS)


Convener: Philippe Roy (Canada, IAMAS)

Co-Conveners: Alexis Hannart (Canada, IAMAS), David Hall (USA, IAMAS), Allen Huang (USA, IAMAS), Scott Hosking (UK, IAMAS), Ashish Sharma (Australia, IAHS)



Rapid advances in artificial intelligence, combined with the availability of enormous amount of data (termed Big Data) is opening new avenues for climate analysis and climate scenarios. The long awaited promises of AI is now common in many disciplines. Applying AI methods, combined with physical knowledge, can improve climate analysis and provide better climate simulations and climate products, notably for high-impact events, such as floods, wildfires and winds.

JM08 - Earth System Models: Assessing the Earth System’s State and Fate from Regional to Planetary Scales (IAMAS , IAPSO, IACS, IAHS)


Convener: Paul Kushner (Canada, IAMAS)

Co-Conveners: Nathan Gillet (Canada, IAMAS), Marika Holland (USA, IAPSO), Gerhard Krinner (France, IACS), Sophie Nowicki (USA, IACS), Manuela Girotto (USA, IAHS), Stephen Déry (Canada, IAHS)



Earth System Models provide our principal means to simulate Earth System processes and to predict the evolution of the planet. Each generation of Earth System Models, including components that simulate the atmosphere, oceans, land, vegetation, ice, snow, and the dynamical and biogeochemical processes that link these components, has provided new insights into the workings of the Earth System, predictions from seasonal to decadal scales, and projections of the future of the planet under greenhouse warming and other sources of radiative and compositional driving. These models have progressively simulated finer scales, and through regional refinement or downscaling can be used to investigate regional-scale climate processes and impacts. This symposium encourages contributions dealing with the many facets of Earth System Model development and application, including new modelling results from the Coupled Model Intercomparison Project Phase 6, development and assessment of models making use of recent Earth observations from ground-based and space-based measurements, prediction of climate on seasonal to centennial timescales, climate change detection and attribution, regional-scale climate modelling and process analysis, high resolution climate modelling, and subgrid scale parameterization development. As a joint symposium, submissions on the latest advances in Earth System Modeling across the atmospheric, biogeochemical, oceanic, cryospheric, and hydrological sciences are encouraged.

JM09 - Satellite Remote Sensing: Vital Information on the Health of our Planet (IAMAS, IACS, IAPSO, IAHS)


Convener: Kaley Walker (Canada, IAMAS)

Co-Conveners: Bojan Bojkov (Germany, IAMAS), Yangbo Chen (China, IAHS), Yasko Kasai (Japan, IAMAS), Paul Kushner (Canada, IACS), Stephen Howell (Canada, IACS), Stefano Vignudelli (Italy, IAPSO), Nicolas Grisouard (Canada, IAPSO), Yanping Li (Canada, IAHS), Hong Lin (Canada, IAMAS)



Space-based observations provide a unique global perspective on the Earth's atmosphere and surface, including the oceans, land, vegetation, ice, and snow.  Current and planned satellite missions from Canada, and international agencies in US, Europe, China and Japan have provided and will  provide a wealth of new information about the Earth system and that can be used to investigate a wide range of environmental and scientific questions.  This symposium encourages contributions dealing with the many facets of space-based remote sensing, including new measurement technologies and techniques, both passive and active; retrieval algorithms; validation of satellite products; assimilation of data into numerical models; scientific results and discoveries and operational utilization and development.



JM10 - Atmospheric Water Generation (IAMAS, IAHS)


Convener: Richard Boudreault (Canada, IAMAS)



Inequality in planet water distribution is enhanced by climate change. The atmosphere is likely to increase its content in the next few decades, furthering disparity in ground water access.  The atmosphere represent a few times the water in rivers and lakes.  This symposium will deal with the micro-physics and technologies developed to condensate and capture atmospheric water.  The symposium will present various atmospheric water generation processes, market analysis and methods of enhancing micro-physics condensation in lower atmosphere. Many approaches are emerging active and passive, guest speakers will be invited and an open symposium for public contribution will be offered.
